Most of these domestic GPU upstarts founded by senior Chinese experts from international giants such as NVIDIA or AMD only have ambitions and development plans, and have no specific products and application solutions. With such a large amount of VC investment in a short period of time, is this another round of “bubble” of domestic chips?

To accurately answer and predict the prospects of this round of domestic GPU financing and entrepreneurship, we must first look at the development history of GPUs, the current status of the global and Chinese markets, and the potential for future application development.

Graphics Processing Unit (GPU) Development Process

Friends who are more familiar with GPUs can skip this part and go directly to the “Global GPU market enters an oligopoly pattern” section.

Graphics Processing Unit (GPU), also known as Display core, graphics card, visual processor, display chip or graphics chip, is a kind of graphics processor specially designed for PCs, workstations, game consoles and some mobile devices (such as tablet computers, smartphones, etc. ) on the microprocessor that runs the drawing operations.

  Domestic GPUs are booming, do Nvidia and AMD feel threatened?

The composition of the Graphics Processing Unit (GPU). (Source: Wikipedia)

Graphics processor is a concept first proposed by NVIDIA when it released the NVIDIA GeForce 256 graphics processing chip in August 1999. Until now, the graphics chip in a computer that handles graphics output was rarely seen as a separate computing unit. The competitor ATI (later acquired by AMD) also proposed the concept of Visual Processing Unit (VPU). The graphics processor can reduce the dependence of the graphics card on the CPU, and share some of the tasks originally performed by the CPU, especially when performing 3D graphics operations, the effect is more obvious. The core technologies used by the GPU include hardware coordinate transformation and light source, three-dimensional environment material map and vertex blending, texture compression and bump mapping, dual texture four-pixel 256-bit rendering engine, etc.

The GPU can be combined with a dedicated circuit board to form a graphics card, or directly embedded on the motherboard as a separate chip, or built into the northbridge chip of the motherboard, and now it is also built into the CPU to form an SoC. In 2007, more than 90% of new desktop and notebook computers had embedded graphics chips, but they tended to be lower in performance than discrete graphics cards. However, after 2009, AMD and Intel have each vigorously developed high-performance integrated graphics processing cores built into the CPU. Its performance has surpassed those of low-end discrete graphics cards in 2012, which has caused many low-end discrete graphics cards to gradually lose market demand. . In the field of handheld and mobile devices, with the increasing demand for graphics processing capabilities, Qualcomm, Imagination, ARM, etc. have begun to “show their talents” in the field of GPUs, but most of them are implanted in the form of GPU kernels. application processor MPU.

Traditional CPUs such as Intel i5 or i7 processors have fewer cores and are designed for general-purpose computing. In contrast, a GPU is a special type of processor with hundreds or thousands of cores optimized to perform massive computations in parallel. While GPUs are best known for 3D rendering in games, they are especially useful for data analysis, deep learning, and machine learning algorithms. GPUs allow certain computations to be processed 10 to 100 times faster than conventional CPUs.

 AI acceleration lets GPUs and Nvidia take off

An AI accelerator is a specialized hardware accelerator or computer system designed to accelerate artificial intelligence applications, especially artificial neural networks, machine vision, and machine learning. Typical applications of AI accelerators include algorithms for robotics, IoT, and other data-intensive or sensor-driven tasks. They are typically designed from many processor cores and typically focus on low-precision arithmetic operations, employing new dataflow architectures or in-memory computing architectures.

GPUs are specialized hardware for processing images and computing local image properties, while the mathematical foundations of neural networks and image processing are similar, and both require processing huge matrix-parallel tasks. Since AI became popular in 2012, GPUs have been increasingly used for machine learning tasks. Especially since 2016, GPUs have become more and more popular in processing AI tasks and are moving in the direction of deep learning. Whether it is AI training in the data center or edge AI inference for autonomous driving, GPUs can handle it calmly. With the popularity of GPUs in AI, Nvidia, which focuses on GPUs, has naturally become the darling of the AI ​​era. It has changed its “underdog” image that has lived in the gap between Intel and AMD for many years, and has become a Wall Street upstart with a market value that exceeds Intel’s.

Deep learning frameworks and AI algorithms are still evolving, making it incredibly difficult to design custom hardware. Reconfigurable devices like field programmable gate arrays (FPGAs) can evolve with AI frameworks and software more flexibly than GPUs. Microsoft took the lead in using FPGA chips for AI inference acceleration, and the application prospects of FPGAs in AI acceleration also prompted Intel to acquire Altera, with the aim of integrating FPGAs into server CPUs so that CPUs can perform AI acceleration while performing general computing tasks.

While GPUs and FPGAs perform better than CPUs for AI-related tasks, custom-designed ASICs based on Domain-Specific Architecture (DSA) concepts can increase efficiency by up to 10x. This AI accelerator uses methods such as optimized memory usage and low-precision arithmetic to speed up computation and increase computational throughput. Internet giants such as Facebook, Amazon, and Google are all designing their own AI ASICs, like Google’s TPUs.

The global GPU market has entered an oligopoly pattern

According to the forecast of authoritative research institutions, the global GPU market will reach US$25.41 billion in 2020, and it is expected to reach US$185.31 billion in 2027, with a compound annual growth rate of 32.82%. By industry application of GPU, the market can be segmented into electronics, IT & telecom, defense & intelligence, media & entertainment, automotive, and others. The automotive segment is expected to witness the highest CAGR due to the widespread use of GPUs in design and engineering applications.

In the global AI chip market, GPU accounts for about 1/3. The high-performance computing (HPC) space has historically been an important market for GPUs, with data predicting that by 2023, 10% of servers will be equipped with GPUs to accelerate AI workloads, up from less than 2% in 2018. With the accelerated convergence of HPC and AI, GPUs are redefining the data center and high-performance computing markets.

The global GPU has entered an oligopoly pattern. In the traditional GPU market, the revenue of the top three Nvidia, AMD, and Intel can almost represent the revenue of the entire GPU industry. In terms of mobile phone and tablet GPUs, the GPU designs of MediaTek, HiSilicon Kirin and Samsung Exynos are mainly based on the public version of ARM Mali GPU or Imagination PowerVR microarchitecture, while Qualcomm Snapdragon Adreno and Apple A series use self-developed GPU microarchitecture.

Nvidia is a recognized global leader in GPU computing, and its main GPU production line “GeForce” is in direct competition with AMD’s “Radeon”. NVIDIA’s four business growth drivers are gaming, data center, professional vision and autonomous driving. Representative GPU solutions include GeForce, DGX, EGX, HGX, Quadro, and AGX. The company’s fiscal 2021 revenue was $16.7 billion, with gaming, data center, professional vision, and autonomous driving businesses contributing 47%, 40%, 6%, and 3%, respectively, in fiscal 2020. After reaching 50% gross margin in 2014, Nvidia’s gross margin in fiscal 2021 exceeded 60%.

In September 2020, NVIDIA announced the acquisition of ARM for $40 billion. If this merger is successful, the combination of NVIDIA’s leading AI computing platform and ARM’s huge processor ecosystem will create a world-class computing company in the AI ​​era. The combined Nvidia will advance computing from the cloud, smartphones, PCs, autonomous driving and robotics to the edge IoT, expanding AI computing to global markets. At the same time, the developers of the NVIDIA computing platform will expand from 2 million to more than 15 million, thus forming the world’s largest computing platform and ecological community.

 Development status and market potential of domestic GPUs

After years of exploration and development, domestic CPUs have formed a certain climate, and the industry and ecology have gradually improved. Domestic CPUs represented by Godson, Zhaoxin and Feiteng began to develop and expand their ecosystems around their respective core products, and gradually developed and expanded with the help of the country’s Xinchuang and the independent development of the semiconductor industry. However, the development of domestic GPUs lags far behind domestic CPUs. It was not until 2014 that Jingjia Micro successfully developed the first high-performance, low-power GPU chip in China, the JM5400.

The reason for this is that the GPU’s own dependence on the CPU’s properties is the main factor. The GPU structure has no controller and must be controlled by the CPU to work, otherwise the GPU cannot work alone. Therefore, it is in line with the development logic of the chip industry that the domestic CPU is one step ahead of the GPU. Furthermore, the development of GPU technology is very difficult. The domestic talent gap is also one of the reasons for the slow development of domestic GPUs.

However, the scale and potential of China’s GPU market is very large, and the huge manufacturing capacity of the whole machine means a huge amount of GPU purchases. Although there have been bottlenecks in the production growth of complete computers and smartphones in recent years, due to the large volume of these two types of products, the large demand for GPUs and the very high value of individual products, the market size is still very considerable. At the same time, with the rapid growth of the whole machine shipments, the demand for server GPUs is also growing rapidly. According to statistics, domestic server shipments reached 3.304 million units in 2018, a year-on-year increase of 26%, of which the growth rate of shipments in the Internet, telecommunications, finance and service industries all exceeded 20%. In addition, there is also a huge demand for GPUs in emerging computing fields such as the Internet of Things, Internet of Vehicles, and artificial intelligence.

Compilation of major domestic GPU manufacturers

 In addition to the several domestic GPU start-ups mentioned at the beginning of this article with AI as their selling point, there are also some domestic GPU manufacturers who have been cultivating in specific fields for many years, and are now seizing the opportunities of the Xinchuang market and “domestic substitution” to expand the application market and accelerate the The development of the domestic GPU industry.

 Jing Jiawei

Changsha Jingjiawei was established in April 2006. It is currently the only listed company focusing on the design of domestic GPU chips. Its main products include JM5400, JM7200 and JM7201 graphics processors. The application markets for notebook computers, all-in-one computers, mobile Workstations, blade motherboards and other desktop office and industrial control fields.

In April 2014, Jingjia Micro successfully developed the first domestic high-reliability, low-power GPU chip-JM5400, which has completely independent intellectual property rights, breaking the long-term monopoly of foreign products in the Chinese GPU market. The first-generation GPU JM5400 is mainly used in the military market, replacing the original ATI M9, M54, M72 and other American GPU chips.

Jingjiawei’s second-generation GPU JM7200 series was successfully taped out in August 2018 and received its first order in March 2019. Compared with the previous generation product, the theoretical performance of JM7200 has been doubled, and the process has also been improved to 28nm. However, the JM7200 still lags far behind the Nvidia GT640 released in 2012 with the full version of the GK107 core in terms of memory bandwidth, pixel fill rate, and floating-point performance.

In 2019, based on the JM7200, the company launched the commercial version JM7201 to meet the high-performance display requirements of desktop systems, and fully support domestic CPUs and domestic operating systems, thus promoting the further improvement of the ecological construction of the domestic computer industry. JM7201 optimizes desktop applications in the civilian market, and introduces standard MXM and standard PCIE graphics cards, which reduce power consumption and size while ensuring performance.

Jingjia Micro GPU has completed the adaptation work with major domestic CPU and operating system manufacturers such as Loongson, Feiteng, Kylin Software, Tongxin Software, Dao, Tianmai; Manufacturers establish cooperative relations and conduct product testing; conduct mutual certification with many software and hardware manufacturers such as Kirin, Great Wall, Cangqiong, Baode, Chaotu, Kunlun, Zhongke Fangde, Zhongke Controllable, Ningmei, etc. to jointly build localization Computer application ecology.

In December 2018, Jingjia Micro raised 1.088 billion yuan through a fixed increase for high-performance general-purpose graphics processors and general-purpose chips for consumer electronics. R&D and industrialization projects. Among them, the high-performance general-purpose graphics processor project includes two GPU chips, JM9231 and JM9271, which are aimed at medium and high-end series products in different application fields. According to the company’s 2020 interim report, the research and development of the next-generation graphics processor is in the back-end design stage. Jingjia Micro JM9 series is the first GPU with unified rendering structure after JM5400 and JM7200 local rendering computing cores, and the number of programmable computing modules has been increased. The performance of JM9231 and JM9271 is comparable to the GTX1050 and GTX1080 launched by NVIDIA in 2016, respectively.

The launch of the JM9 series will shorten the company’s GPU level and international leader to 5 years, greatly enhancing the company’s competitiveness in the GPU field.

 Login Technology

The first-generation product Goldwasser that Denglin Technology spent three years developing has been mass-produced in the third quarter of 2020. The product is currently cooperating with leading companies in the Internet and security fields for integration and business testing. The company adopts the independently innovative Minsky architecture (software-defined heterogeneous artificial intelligence computing platform), and fully supports various popular artificial intelligence network frameworks and underlying operators on the premise of providing compatible CUDA/OpenCL hardware acceleration capabilities. Compared with NVIDIA’s current mainstream cloud inference products (T4), Denglin Technology’s products have a smaller chip area on the same process. Under the same power consumption, depending on the AI ​​network, the computing efficiency can be improved by 3-10. At the same time, it also reduces the dependence of chip performance on external memory throughput.

 Are Nvidia and AMD under threat?

Driven by AI-accelerated computing, independent innovation of domestic semiconductors, and venture capital, the domestic GPU, which was originally calm, suddenly took off, setting off a storm in the already restless Chinese semiconductor industry. This is definitely a good thing for the development of the semiconductor industry and the domestic GPU industry, but the author thinks that this storm chased and set off by capital is a bit too hot. Even with senior GPU R&D experts and strong capital support, it is unrealistic to create an industry from scratch to compete with global GPU giants. Are Nvidia and AMD feeling threatened? In my opinion, apart from the loss of some technical management talents and the poaching of R&D personnel, domestic GPUs will not be able to shake their status in the short term.

The growth in demand for GPUs in specific fields such as national Xinchuang market demand and industrial control will bring opportunities for domestic GPU manufacturers such as Jingjiawei to grow and expand the market. As for these GPU upstarts with AI as their main application market, in addition to coming up with truly comparable GPU chips, they also need to work hard on ecological construction and AI scene implementation to prove that they are indeed getting so much money. Value for money” can eliminate the suspicion of “bubble”.
