1905 movie network news The music martial arts film "Noisy Jianghu" jointly produced by Penguin Film and Budou Film has recently started in Xiangshan. Director O ‘Tan Kai made a joint appearance with starring Shi Yunpeng, Ma Qianqian, Ji Muchuan and Julian.

Breaking traditional barriers and enriching innovative elements have attracted attention.

　　"Noisy Jianghu" is an original music martial arts film produced by famous director Cheng Qiang and directed by young director Ou Tan Kai. It tells a series of stories about the rise of Baile in the Northern Song Dynasty, in which Dashengfu, represented by the imperial court, and Da Yuefang, led by Guqin School, Guigu School, Dazhong School, Pipa School and Tiedi School, were ready to move, and they fought for the Classic of Boya in order to become the best in the world. The male and female protagonists also grew up through many experiences and felt the true meaning of love and justice.

　　As a martial arts film with the theme of music, this film combines the most popular film and television elements, which is a rare innovative theme at present, whether it is the cinema market or the scope of online movies. In recent years, young director O ‘Tan Kai has made many excellent works, and his film "Youth Feed the Dog" has won 7 nominations and 4 awards at home and abroad. This time, director Cheng Qiang and director Ou Tan Kai can be described as a strong alliance, which will be strictly controlled to ensure the quality and production of the film.

Strong production team, painstaking polishing, careful preparation and excellent creation

　　The screenplay of this film was carefully crafted by director Ou Tan Kai and screenwriter Li Ranning, and was repeatedly scrutinized and revised, striving to be more excellent on the basis of originality. Not only that, but also invited many well-known domestic film and television drama masters to create together, and went to Yinchuan, Ningxia, Alashan League, Chifeng, Xiangshan Film and Television City and other places to collect scenery in order to achieve the highest presentation of the story effect.

　　Before the start-up, the crew arranged intense and intensive training plans for the actors, from various professional musical instruments learning to one-stroke-one-style martial arts action guidance, in order to make the performance more real and show the role vividly.

Yan value acting has a strong lineup, and the bones are expected to join.

The movie "Noisy Rivers and Lakes" not only enables a large number of outstanding young actors with online acting skills and off the charts’s value, but also has many screen "old drama bones" to escort them.

The leading actor, Wen Muge, is played by Shi Yunpeng. Born as a child star, he has appeared in many famous works, such as Ode to Joy, Mu Yun Ji at Sea, The Longest Day In Chang’an and so on, which are well known to the audience. Ma Qianqian, a new flower, not only left a deep impression in The New Six Fingers Qin Magic, but also played the role of Jiang Miaoxian in this film.

In addition, the film also features Zhu Tiehe, the actor of Ouyang Feng in the 94th edition of Legend of the Condor Heroes, Zhu Hui, an actor who has participated in Thirty-three Days of Lovelorn, The Ordinary World, The Story of the Clouds on the Sea and The Longest Day In Chang’an, and Miao Fu, a famous cross talk actor, etc., which adds more highlights and highlights to the film and arouses the infinite expectations of netizens.

In today’s auto market, there are too many brands to count, just like mobile phones, so many choices are eye-catching. This brand used to be quite low-key, but recently a new car came out, which made it hot again. This car is most interested in its appearance, but if the price is right, it is estimated that many people will be tempted.

At the auto show, our price was announced, which was 1.4-1.86 million. At that time, my heart thumped. This time, I really dared to ask for the price, which was directly on a par with those international brands. The entry fee is 1.46 million yuan, but the actual purchase can be 200 thousand yuan cheaper. Compared with this, the price of Hongqi Guoya does not take advantage.

But I always feel a little sorry in my heart. Hongqi Guoya is so concerned, certainly not just because it looks good. Who still stares at things they can’t afford every day now? The market was so interested in Guoya that Hongqi had a chance to make a fortune. If the price of Guoya can be set at around 800,000 yuan, maybe it will become an explosive car like Ideal L9 and Wenjie M9. These cars are based on their strength, which has compared foreign luxury cars with the same price, and has also brought a new trend. What everyone values now is comfort and intelligence.

If Guoya can set it at 800 thousand, it will definitely attract a large wave of car owners who originally wanted to buy S-class and 7-series. Now the performance of S-class and 7-series is a bit weak, and the appearance and quality are not as good as before, so it is no longer everyone’s first choice. Guoya had the opportunity to become a new popular choice and a new love for everyone. Unfortunately, as soon as this price comes out, it is estimated that many people will have to hesitate.

Just like that, although the price is similar to X3, Q5 and GLC, it feels like flagship models such as X7 and GLE, which is why they can catch fire. Everyone wants the feeling of being tall, but the wallet is limited, so if the domestic car can be grounded in price and unambiguous in configuration, it will definitely attract a large number of fans.

When it comes to S-class cars, although they are all luxuriously decorated and have long bodies, their position in the market is far from perfect. If Guoya can give an experience at the price of S-class, it will not only be popular, but also make the red flag brand re-popular, just like Ideal, Ask the World and Xiaomi, becoming the new favorite in the market.

But now the starting price of Guoya is 1.4 million, and this price always feels a bit outrageous. Compared with the S-class in Maibakh, this price seems a little high. Brand aside, domestic cars are more expensive than imported cars, which makes people a little confused. Although there are not many innovations in recent years, after all, it has a hundred years of history and technology. How dare Hongqi set the price so high?

Let’s talk about the cost and profit. It is unknown how much Guoya can earn when it starts selling at 1.4 million yuan, but for most domestic brands, it is no problem not to lose money by inserting 800,000 3.0T large cars. Even if you lose money at the beginning, if you can kill the S-class /7 series, it will be cost-effective, because it will make Hongqi and Guoya famous in history, and you can also earn a lot of money through subsequent models.

In the final analysis, if the red flag is still entangled in the question of "why can’t domestic cars be more expensive than foreign brands", then Guoya may have to stand on the top of the "most expensive domestic cars" and watch the opportunity slip away. But if we can have the courage of the new forces, Hongqi may be able to grab market share from S-class and 7-series.

Unfortunately, Hongqi chose to be conservative. So, what do you think of Guoya’s car? No matter how beautiful the design is, the price is higher than that of Maibakh. Will it be buried like this? If it sells for about 800,000 yuan as I said, do you think those rich people will give up S-class and 7-series and choose Red Flag instead?

Recently, when law enforcement officers carried out a normal cruise in the Yangtze River Zhenjiang finless porpoise nature reserve, they found many finless porpoises playing in the river.

The Yangtze finless porpoise is a national first-class protected animal and an extremely endangered species in the world. After the extinction of the baiji, it became the last cetacean in the Yangtze River, with only about 1,000 surviving. As the only remaining mammal in the Yangtze River, her living condition is an important symbol of the health and stability of the Yangtze River life system. Zhenjiang section of the Yangtze River has been an excellent habitat for Yangtze finless porpoises since ancient times. At present, there are about 35 finless porpoises living all year round. With the implementation of the strategy of "jointly protecting and not developing" in the Yangtze River Economic Belt, the ecological environment of the Yangtze River has been continuously improved, and "mother and child dolphins" and finless porpoises have appeared in Zhenjiang Yangtze River Dolphin Nature Reserve, Wufeng Mountain waters in Zhenjiang section of the Yangtze River and Sanjiang Camp waters.

In recent years, Zhenjiang Maritime Safety Administration has thoroughly implemented the deployment requirements of Jiangsu Maritime Safety Administration and Zhenjiang Municipal Party Committee and Municipal Government, placed the protection of the ecological environment of the Yangtze River in an overwhelming position, and carried out a series of vivid practices of ecological protection of the Yangtze River. First, adhere to joint efforts and improve the ecological protection mechanism. In 2021, Zhenjiang was promoted to establish the Yangtze finless porpoise protection alliance, and 10 units in Zhenjiang jointly promoted the Yangtze finless porpoise protection work. In 2022, Zhenjiang will be promoted to issue long-term management measures for the prevention and control of ship pollution in ports, and a pollution control pattern for ships and ports with reasonable layout, smooth connection, efficient operation and strong supervision will be clearly established. Actively promote the implementation of the first local regulations on the coordinated protection of single-species watershed areas in the country in the town, and continuously improve the protection mechanism of unified leadership by the government, division of labor by departments, social participation and regional coordinated promotion. The second is to adhere to strict management and improve the effectiveness of on-site supervision. Innovative implementation will include the implementation of the "one hundred and two free services" requirements for ships and docks in the daily supervision and inspection work of the rapid response disposal center, strengthen the "124" special office to conduct unannounced visits, literacy and counterfeiting, and severely crack down on illegal activities such as direct discharge of domestic sewage and false reporting of hazardous chemicals. We will comprehensively deepen the working mechanism of "daily report" on hazard prevention work and "monthly notification" on pollution prevention data, and compact the main responsibilities of the terminal and maritime departments. Deepen the use of the credit supervision mechanism in the field of ship pollution prevention and control, solidify the "interview+rectification" model, further find out the base, control risks, and make up for shortcomings. The third is to adhere to green first and promote long-term treatment. Optimize and upgrade Liuwei Water Comprehensive Service Area,Actively build a online celebrity community on Liuwei River, efficiently test-run Gao Qiao Water Green Service Area, promote the formation of a cluster layout of service areas in Zhenjiang section of the Yangtze River, effectively change the supervision concept of ship pollution prevention and control, and take a good "new idea" of pollution prevention and control.

　　On June 3, 2020, local time, an American high school student threw a hat to celebrate graduation. (data map)

　　Overseas Network October 14th　According to a report by CNN on the 13th, the average score of American high school graduates in the College Entrance Examination (ACT) dropped to the lowest level in 30 years, and more than 40% of the candidates failed all the examination subjects.

　　The comprehensive average ACT score of the class of 2022 is 19.8 (with a total score of 36), which is lower than 20 for the first time since 1991. More importantly, more and more senior high school students have failed to reach any subject passing line set by ACT, indicating that their preparation for university courses has declined. According to the ACT report, among the 2022 graduates who took the ACT exam, 42% did not reach the passing line in any subject of English, reading, science and mathematics. In contrast, in 2021, 38% of candidates failed to reach the passing line of all subjects.

　　CNN9 reported in September that the math and reading scores of 9-year-old children in the United States also plummeted from 2020 to 2022, falling to a level not seen in decades. Peggy Carr, Commissioner of the National Center for Education Statistics, said that it was not just the epidemic that interrupted students’ learning. Shooting on campus, violence, interruption of classes, shortage of teaching staff and absenteeism, cyber bullying, and students seeking mental health services are also increasing. These information may explain the serious decline of American students’ grades.

Special feature of 1905 film network While many people are still trying to find a solution for the gentle and considerate Guan Tao, Qiao Shaoting, who is both righteous and evil in Out of Court, has "seamlessly joined" into the audience’s field of vision.

All lawyers, all of them. The coincidence of the same person setting up a "bully screen" has once again become an opportunity for him to prove himself.

From the role of "Aunt Xu" in "An Jia" to the continuous performance of realistic works such as "There are so many beauties in the country" and "Ebola Frontline", Luo Jin, who bluntly said that he didn’t like being labeled, finally opened up the pattern and ushered in more possibilities as an actor besides the "costume goddess".

Guan Tao-Qiao Shaoting　How was the "Lawyer Edition" Luo Jin tempered?

The Story of Xingfu’s "Out of Court" was broadcast, which made Luo Jin unexpectedly unlock the achievement of "professional lawyer".

On the one hand, Guan Tao, a gentle and warm man who is inspirational and entrepreneurial, and on the other hand, Qiao Shaoting, who was "crazy" when handling a case and could even be sent to a detention center, such a contrast is concentrated on the same person, but it is not inconsistent.

Guan Tao, who seems to be elegant, is not perfect. Qiao Shaoting’s "bad" will not change his sincere background. Luo Jin likes the complexity of the two characters in human nature.

But the process of becoming a lawyer is difficult for actors to refresh their cognition. For a long time in preparation for the role, he repeatedly read various versions of Criminal Law, and kept chanting various professional words in his mouth, hoping to be close to the lawyer’s proficiency in using various laws.

In addition to mastering book knowledge, the process of going to the law firm for field experience is of course essential. By observing the real life state of lawyers, Luo Jin also felt that the real "out of court" was not as chic as shown in the drama.

"Those moments of truth in court are actually just results. The process (behind), including evidence collection and consideration of the entry point of the case, is very, very heavy. "

Every time he meets a new person, Luo Jin feels that the most important thing is how to "put himself in" properly.

"In recent years, I have made many modern dramas, most of which are ordinary people in our lives, so I will provide my understanding of life and people according to the script."

For example, before filming "An Jia", he also went to the housing agency to start his business. "Aunt Xu’s daily chicken flies a dog to jump, but Luo Jin’s real experience is far more complicated and exaggerated.

"Actors must believe in themselves," he said. Only when actors put themselves in their shoes and have seen the "dog blood" and "drama" in life can they convince the audience of your expression with their performances.

Can you still "fight" after 20 years of employment?Performance is "a walk in the role"

"20 years in business … … Oh, I have been in business for so long. " Cue was suddenly caught in the interview, and Luo Jin himself was very emotional.On this timeline, "Actor Luo Jin" has left many memorable "nodes", although he thinks he is not productive.

In addition to the "transformation" modern drama mentioned in the above article, Splendid Weiyang and Return to Come, which were completed with his wife, and the title of "costume goddess" for him, are obviously worthy of being on the list.

Talking about past works, Luo Jin did not hide his cherish and love for them: "What I particularly like in the works … … It’s much better to count them one by one (laughs). "

Of course, roles and works have to face all kinds of judgments from the outside world, but from a subjective perspective, it is not only an imprint left on the professional level, but also a parallel life that belongs to the actors alone.

At present, Luo Jin has entered the group "Wilderness" and started his new "role life". No matter how long you have been in the industry and received different roles in ancient costumes or modern times, for actors, the job is nothing more than playing good characters and telling good stories.

The only thing that has changed may be the deepening understanding of human nature and life with age and experience. "I am glad to have met many different roles in filming these years."

Luo Jin said that the choice of scripts often represents the most urgent feelings and expressions at different stages. "As I often say, every role I have played, no matter whether the public’s evaluation of me is good or bad, I really went to his life with my heart."

Of course, Luo Jin, who has repeatedly said bluntly that he doesn’t like being labeled as "genre", will not deliberately avoid or choose a certain kind of script and role. In his view, compared with the deliberate pursuit of becoming a "middle-aged traffic that can be played", today’s self is more willing to be happy with the completion and two-way role.

"No matter whether the external evaluation is good or bad, the life of these characters has brought me a very big change, open-minded, relieved … …” When talking about the future, Luo Jin lamented: "It is good for me to play simple characters around me."

1905 movie network news Produced by Warner Bros., the phenomenal hilarious animation created by the gold medal team today exposed the feature footage of "sugar-coated cannonball". The Lego warrior was kidnapped, and the alien general Mei Hengqiang kidnapped everyone and flew them to the Lego universe. The Infinite Reflection Palace made its first gorgeous appearance, and the universe-level customized SPA charmed everyone. The secret of Lucy Woman surfaced, and the splendid wonders of Sista galaxy were about to be exposed. Come to the cinema to decipher the universe with Lego villains!

　

Vampire DJ leads Lego universe trend, and the alien SPA is full of luxury.

In the feature clip of "sugar-coated cannonball" exposed by The Lego Movie 2: The Second Part today, alien general Meheng drives a spaceship and takes the residents she took from the city of doom, such as Lucy, Beard Steel, Batman, Unicorn Cat and Benny, to the mysterious and vast universe. At the first stop of this alien trip, Lucy and others came to the spa and the "Re-education Celebrity Center" run by vampire balthasar and his charming staff — — Infinite reflection palace. Here, the heroes from the city of Doomsday enjoy the high-end SPA in the universe. According to the different needs of everyone, the vampire boss who works as a part-time DJ specially tailored different nursing schemes for them: the beard steel was washed with barnacles, Batman focused on the chest muscles and back muscles, and even Lucy Xia almost exposed her "secret" hidden for many years here. However, everything that seems to be enjoyed is just a "sugar-coated cannonball" brought by General Meiheng, and the "good play" waiting for everyone has not yet begun.

　

Super special effects to create Lego space wonders, small building blocks contain infinite possibilities.

As an important scene in The Lego Movie 2: The Second Part, Sista Galaxy not only drives the plot development of the whole movie, but also represents the first appearance of Lego Universe. Therefore, the design of Sista Galaxy also makes the production team take great pains. Gorgeous modeling, colorful color matching, relaxed and pleasant atmosphere, and various forms of alien creatures have formed a strong contrast with the desolation and ruin of the city of doom.

In order to create a space wonder of the Sista galaxy, the production team not only separately rendered, colored and polished each digital Lego block, but also specially added two powerful female characters — — Do as you please, queen and general mahon. In this regard, the production team said: "Lego is not only a boy’s toy, but also girls can find their energy in the Lego world. Creativity is the true meaning of Lego, which is why the whole world will be attracted to Lego."

On October 17th, the Bureau of Industry and Security (BIS) of the US Department of Commerce updated the "Export Control Rules for Advanced Computing Chips and Semiconductor Manufacturing Equipment", which revised and strengthened the rules of October 7th, 2022. The rule is still in the publicity period and will take effect in 30 days.

The new regulations will restrict NVIDIA’s sales of chips to China market, saying that stricter control will be imposed on NVIDIA A800 and H800 chips, which will be reviewed within 25 days to determine whether a license is needed to sell such chips to China. At the same time, there are 13 China GPU enterprises listed in the entity list, including Moore Thread, Wall Technology and so on.

In this regard, NVIDIA responded that it will not have an immediate and substantial impact on its income, but it may cause damage to its long-term development.Previously, NVIDIA disclosed in the second quarter earnings conference call that China’s sales accounted for 20-25% of the data center.

For wall technology and Moore thread, being included in the entity list means that if you can’t get permission, you can’t not only import American technology or products, but also use a fab based on American technology or equipment to OEM chips for them.

Upgrade chip export control measures

According to the regulations of 2022, the United States prohibits the export of chips exceeding two standards: one is the power standard, and the other is the "interconnection bandwidth", that is, the communication speed standard between chips. According to the new regulations, the communication speed will be replaced by "performance density", that is, the number of floating-point operations per square millimeter, which prevents enterprises from finding alternatives.
For example, in order not to violate the export restrictions of the United States, NVIDIA has launched a special edition chip for the China market-A800/H800 which limits the communication speed (the processing speed is about 70% of A100/H100). Although it retains strong computing power, the time for training AI big models will increase. Even so, A800/H800 is still considered as the best data center chip for AI training/reasoning in China market. There is also Gaudi2, a special AI processor launched by Intel for the China market.
The revised export control measures will prohibit American enterprises from selling data center chips running at 300TFLOPS or above to China. If the performance density of the chip reaches or exceeds 370GFLOPS per square millimeter, the chip with the speed of 150-300TFLOPS will be banned from sale. Chips running at the above speed but with low performance density belong to the "grey zone", which means that enterprises must inform the US government about their sales to China.
Some analysts said that the new measures may also include NVIDIA’s flagship game graphics card.RTX4090. The latest news shows that the US Department of Commerce has clarified the export control policy, which is aimed at4090The ban on graphics cards allows consumer applications to be exempted from export. this means4090Graphics cards can still be retailed in the consumer market in China (including Hongkong and Macau), but they are not allowed to be used for commercial and production purposes.

In order to prevent enterprises from bypassing chip restrictions through Chiplet’s chip stacking technology, the new measures also extend the new regulations to more than 40 countries to export advanced licensing requirements, so as to prevent AI chips such as A100 and H100 series from being exported to China from other overseas regions; In addition, licensing requirements for chip manufacturing equipment have been put forward for 21 countries outside China, and the list of equipment prohibited from entering these countries has been expanded to limit the manufacturing capacity of advanced chips below 14nm in China.
The new export control regulations have also added a list of items in many sub-fields, including ASIC (Application Specific Integrated Circuit), FPGA (Field Programmable Gate Array), SRAM storage and calculation integrated chip, Chiplet, multiple exposure technology, NPU (Neural Network Processor), etc., which are all within the control scope of the United States.
If only the peak performance is limited, chip companies can also launch small-volume products with low performance and power consumption for the China market, and then form a cluster through high-speed connection, and finally achieve the expected cluster performance. However, the terms of chip performance density have blocked this road. This new regulation will fill the "loophole" of the previous chip restrictions, include some AI chips that originally met the previous technical parameters, and prevent China enterprises from purchasing American AI chips through overseas subsidiaries.
When controlling the export of chip companies, the performance of American companies will also be affected. The China market has long been the largest market for American chip companies outside the United States. In 2022, the revenues of NVIDIA, Intel and AMD in Chinese mainland (including Hong Kong, China) accounted for 21.4%, 27.2% and 22.1% respectively.

It is worth noting that enterprises in Taiwan, China, such as ASUS, Gigabyte and MSI, still have a large number of end customers in Chinese mainland. According to the statistics of Chinese mainland and Taiwan, China, the revenue of NVIDIA, Intel and AMD in China market accounted for 47.3%, 40.3% and 32.1% respectively.

The demand for computing power in AI era has increased exponentially.

Since the end of November 2022,ChatGPT, an artificial intelligence conversation and chat robot released by American startup OpenAI, quickly became popular., only useThe number of registered users exceeds one million in five days.,And broke through 100 million in two months.,Become the fastest growing consumer application in history..
The AI big model represented by ChatGPT has opened a new wave of science and technology of productivity innovation.Man and machine are no longer limited to simple imperative interaction.,Machines can understand complex intentions, whichSubvert many formats in the past Internet development., alsoHave a profound impact on the real economy and industrial development..therefore,GPT was founded by Microsoft founder bill·Gates rated it as the most important technological progress since the graphical interface.,It was called the iPhone moment in the field of artificial intelligence by NVIDIA founder Huang Renxun..
When everyone is immersed in the amazing "vitality" of the super-large language model, AI, a concept that has existed for decades, has become the core variable of the development of human society in the next few decades. Behind AI is the organic combination of computing power, data and algorithm.
In essence, the explosion of ChatGPT is an explosive embodiment after the comprehensive ability of software (data, algorithm) and hardware (computing power) in the field of AI has been greatly improved. With the wide application of cloud computing, especially deep learning has become the mainstream way of AI research and application, AI’s requirements for computing power have been increasing rapidly.
When we talk about the performance of AI chips, the first indicator that comes to mind is computing power. Computational powerIt is the infrastructure of algorithms and data, supporting algorithms and data.Refers to the amount of computing tasks that a computer system can complete.,Usually used to describe the ability to process data, using FLOPS.(Floating Point Operations Per Second)Represents the number of floating-point operations or instructions that can be completed per second. In the early decades of AI development, the required computing power increased according to Moore’s Law-it doubled in about 20 months.

In 1950s, Claude Shannon, an American mathematician, trained a robot mouse named Theseus to navigate in the maze and remember the path. Theseus was built on the basis of 40FLOPS；. In 2012, AlexNet (an image recognition AI) marked the beginning of the era of deep learning, and the time for doubling computing power was greatly shortened to six months; In 2015, the emergence of AlphaGo brought the era of large-scale AI model, and its computing needs were greater than all previous AI systems.
Compared with the traditional AI algorithm,The large-scale model has been greatly improved in parameter scale.,The parameters generally reach hundreds of billions or even trillions..For example, the GPT series of OpenAI.,The original GPT-1 has 117 million parameters.,The number of parameters to GPT-3 has reached 175 billion,And the corresponding ability has been greatly improved..
The huge demand of AI algorithm model for computing power has promoted the development of chip industry today. According to OpenAI, since 2012, the amount of computation used in global AI training has increased exponentially, doubling every 3.43 months on average. At present, the amount of computation has expanded by 300,000 times, far exceeding the growth rate of computing power.
Generally speaking, AI chips are called AI accelerators or computing cards, that is, cores specially designed to accelerate AI algorithms (other non-computing tasks are still handled by CPU); In a broad sense, chips for AI computing applications can all be called AI chips.This brings the hardware giants in the field of computing power into people’s sight again.The computing power value contained in the underlying hardware such as CPU, GPU, FPGA and ASIC will be reshaped.

At present, GPU is the main choice of AI computing power becauseGPU was originally designed for graphics rendering.,The calculation involved in graphic rendering is highly parallel,This parallelization makes GPU very suitable for large-scale data parallel computing such as machine learning and deep learning.. GPUParallel computing ability can greatly improve computing efficiency and shorten the training and reasoning time of AI algorithm, which has become the core of computing power in the AI era.
andSpecifically, the rendering process is the calculation of the position and color of geometric points, both of which are mathematically multiplied by four-dimensional vectors and transformation matrices, soMore than 80% of the GPU is a computing unit.With computing units such as tensor kernel and matrix multiplication,In comparison, only 20% of CPU is an arithmetic unit.So GPUCommon machine learning and deep learning operations can be performed faster.：Such as convolution and matrix multiplication.Compared with general computing units, these computing units,It has higher efficiency and faster speed.
When performing calculations such as deep learning, alsoA lot of memory and high-speed memory bandwidth are needed to store and process massive data..Compared with other hardware, GPU(Such as CPU),It has higher memory bandwidth and larger memory capacity.,Data can be stored and processed more effectively.,So as to improve the calculation speed..
at present,With NVIDIA A100, for example.、Release of H100 and other models.,Compared with other hardware, GPU has great advantages in computing power.The work of GPU has gradually changed from graphic processing at the beginning to computing.In the training stage of deep learning, its performance is unparalleled.Become the most suitable hardware to support AI training and learning.It is applied to data center acceleration and some intelligent terminal fields.
According to JPR statistics, in the first quarter of 2023, the market share of GPU in NVIDIA reached 84%, and it was the leader of GPU market.heroWeida first proposed the concept of GPU in 1999, launched CUDA computing platform in 2006, and released the supercomputer DGXGH200 in May 2023. Its computing power scale reached 1Eflops, which supported the training of trillion-parameter AI large models and provided linear scalability for giant artificial intelligence models. NVIDIA has become a key supplier of AI computing power based on its ecosystem construction such as GPU and CUDA.

• As for CPU, because GPU can’t work alone, it must be controlled by CPU to work. CPU can also be used as an AI chip alone, processing complex logical operations and different data types. Although it is compatible, it is wasteful. When a large number of data with unified processing types are needed, GPU can be called for parallel calculation.
• However, FPGA has the characteristics of low energy consumption, high performance and programmability. Compared with CPU and GPU, it has obvious performance or energy consumption advantages, but it requires high users.Through FPGA, the cost of R&D and debugging can be effectively reduced, the market responsiveness can be improved, and differentiated products can be introduced. Technology giants have laid out platforms of cloud computing and FPGA. With the gradual enrichment of the developer ecology of FPGA and the increase of applicable programming languages, the application of FPGA will be more extensive.
• ASIC can optimize the hardware level more pertinently, so as to obtain better performance and power consumption ratio. However, the design and manufacture of ASIC chips need a lot of money, a long research and development cycle and engineering cycle, and the deep learning algorithm is still developing rapidly. If the deep learning algorithm changes greatly, FPGA can quickly change its architecture to adapt to the latest changes, and once ASIC chips are customized, it is difficult to modify them.

• AI chips can also use NPU, which has sprung up in recent years. Under the same chip area, NPU can achieve dozens of times the AI performance of GPU. Nvidia has also stuffed many Tensor Core in recent generations of GPUs, but if NPU is used, it can not completely rely on the CUDA ecology in NVIDIA, so many companies from Intel, AMD and even China have taken a share.

  In terms of performance, Huawei’s NPU is not inferior to NVIDIA’s products in AI performance, and what it lacks at present is "ecology". Only when there are enough developers involved can the ecology be established, but the transformation is "painful", which means a lot of code refactoring.

Generally speaking, GPU is currently the most mature and widely used general-purpose chip for AI computing in the market, and will continue its leading position in the short term. In the period when the algorithm technology and application level are still shallow, its powerful computing power, low research and development cost and universality will continue to occupy the main market share of AI chips.

From the "all-round no-dead-angle" upgrade ban in the United States, we can see that behind the contemporary chip war is a broader and more far-reaching strategic AI war, and the competition for computing power will become more and more fierce, which will determine the map of scientific and technological strength in the next few decades. A seemingly impenetrable network seems to not only kill the domestic high-end computing chip industry, but also block China’s advanced road to AI revolution.

In the short term, domestic AI chips can’t adopt foreign advanced EDA and IP at the design level, nor can they be manufactured by advanced processes, so they are faced with the challenges of increasing product power consumption and reducing energy efficiency ratio, and their competitiveness has declined, but this decline is only temporary. In the long run, the only way for domestic AI chip companies to be free is to face up to difficulties, unite as one, warm up with the supply chain and build a sound and complete supply chain that is not restricted by the United States.

Experts suggest that, on the one hand, efforts should be made in the fields of EDA tools and IP to make up for each other’s shortcomings, enhance their strength and accelerate the pace of localization; On the other hand, efforts should be made to build an unrestricted advanced technology OEM line, to tackle the key problems in the manufacturing process of the flow sheet and to build a sound and complete industrial chain.At the same time, break through the barriers between industry application, chip research and development, system development and university research, form cross-enterprise, cross-field and cross-industry cooperation, and then promote the all-dimensional development of the chip industry.

In recent years, China’s semiconductor industry has been crawling forward with gunfire, and today’s "gunfire" has been upgraded to the level of "atomic bomb". Fortunately, in the context of escalating sanctions and shortage of computing power, domestic AI companies and GPU companies are struggling to move forward. Huawei, Ali, Baidu and Tencent have all been developing their own AI chips. AI chip companies include listed CAMBRIAN, Jingjiawei and Haiguang information, as well as core technology, Suiyuan, Hanbo, Muxi, Biyu, Moore Thread, Tianzhixian and other enterprises, which have achieved fruitful results in architecture innovation, design, OEM and application. The data shows that the development of local AI chip manufacturers in China is in a stage of rapid growth. In the first half of 2023, the market size of China’s accelerated chips exceeded 500,000. From a technical point of view, GPU cards occupy 90% market share; From the brand point of view, local AI chip brands in China shipped more than 50,000 pieces, accounting for about 10% of the total market.

After the frequent introduction of bans, some American enterprises are worried about "stimulating the development of an ecosystem dominated by China". Unfortunately, these "worries" will come true in the near future.However, the reaction will be as strong as the intensive sanctions, and the industrial chain of China AI chips will break through in an all-round way and the supply chain will be self-controllable.
