Shipments of CPUs, GPUs, and chipsets have been falling due to the weakening demand for PCs, gaming devices, and cryptocurrency mining machines. This recent development has also constrained the growth of the market for ABF substrates. Currently, the demand situation for this material is exhibiting signs of uncertainty.

Regarding the distribution of the demand for ABF substrates, applications that are driving growth are cloud services, AI, and automotive electronics. CPUs, GPUs, FPGAs, and switch ICs are chips that are deployed in servers purposed for a wide range of applications related to cloud services and endpoint AI technologies. Meanwhile, other AI-related applications require high-end ASICs. At the same time, more and more high-end SoCs and MCUs are embedded in vehicles. All in all, these aforementioned applications will spur the demand for ABF substrates. Additionally, package size continues to increase for high-performance ICs. This trend, too, will sustain the demand for ABF substrates over the long haul. By contrast, the PC market has matured, so the related demand is shrinking. From a long-term perspective, the influence of the PC market on the demand for ABF substrates will gradually wane.

TrendForce forecasts that the scale of the global market for ABF substrates will expand from US$9.3 billion in 2022 to US$17.1 billion in 2026, thus showing a CAGR of 16.4%. Due to the influence of the US technology export restrictions against China, the demand for ICs purposed for HPC will be higher than expected for the period from 4Q22 to 3Q23. This, in turn, will also further raise the demand for ABF substrates.

Then, starting from 4Q23, exports of HPC chips to China will start to slow down. However, demand will continue to grow for ASICs, AI chips, SoCs, and MCUs at that time. The growth in these application segments will offset some of the negative effect of the US export restrictions on the market for ABF substrates. In terms of the supply-demand dynamics of ABF substrates, a balance will gradually be attained in 2024. However, demand will get stronger in 2025 and 2026, so supply could tighten during that two-year period.

Current U.S. sanctions on China have extended their reach to strike at HPC and sectors such as aerospace, automotive market, and military industry. TrendForce indicates, the market for high-end computing chips (including CPU, GPU, etc.) has borne the brunt of these restrictions at this stage, while those providing related storage such as DRAM and NAND Flash also face potential supply disruption. At present, this not only includes domestic companies in mainland China but also extends to related US-based suppliers. Among them, server companies that rely on high-intensity computing will face greater scrutiny.

Impact analysis on server terminal shipments

In terms of server terminal shipments, since relevant component suppliers have not yet been able to confirm whether services provided by the four major cloud service providers (CSPs) in China, Baidu, ByteDance, Alibaba, and Tencent, involve military use, before CSPs sign MOUs (memoranda of understanding), component manufacturers may temporarily delay shipments to the Chinese market. However, TrendForce believes, due to the fact that current CSP buyers’ component inventories remain sufficient, the short-term impact on global server market shipment performance is relatively low and long-term impact depends on the evolution of the US Department of Commerce’s rules.

Huawei and Sugon, two companies that have received attention at this stage due to the US ban, have previously withdrawn from the x86 server market and turned into cloud business providers and whole server delivery has been transferred to other domestic OEMs and outsourced computing power leasing, so as not to be affected by sanctions. However, due to the previous CPU ban, Sugon has turned to AMD to obtain authorization for localized chips, which may be significantly curtailed by this ban. In 2022, Sugon’s market share in the overall server market will be approximately 2.3% and 8.5% of the Chinese market.

TrendForce believes, it cannot be ruled out that relevant Chinese OEMs may have server products that may be rendered to government supercomputing centers in the future. Inspur, H3C, and Lenovo will face more exacting future scrutiny and, if consequences intensify, the mainland Chinese industrial chain may feel direct effects. Although commercial servers are not currently on the list of directly restricted items, if friction between the United States and China intensifies in the future, it cannot be ruled out that the U.S. Department of Commerce will add more potentially risky Chinese server OEMs and CSPs onto the UVL list. If certification cannot be realized within 60 days of being included in the UVL list, these entities will be included on the entity list. The worst case scenario will be a future trend of negative growth in Chinese server demand.

Since the restrictions enumerated in this ban are primarily concentrated in the HPC field, the greatest factor affecting Sugon is the company largely providing server OEM to government departments including in supercomputers, military aerospace, and government server farms. At present, there are 8 national-level supercomputing centers in mainland China and the supercomputer located in the center of Wuxi is the headquarters of China’s self-developed chips including the self-developed Sunway TaihuLight. As the U.S. Department of Commerce continues to strengthen its sanctions, China’s supercomputing technology and domestic research capabilities will be severely damaged in the future.

Impact analysis on GPU and CPU sectors

At present, companies utilizing high-end graphics cards are primarily concentrated in the HPC sector. In terms of CSPs, Alibaba and Baidu are the largest companies in mainland China. These two CSP companies account for up to 60% of the market share of GPU usage in China. Before the previous ban at the end of August, Chinese CSP operators had to submit purchase applications before procurement but they could not apply at all after the ban. However, based on the premise that buyer inventory levels on hand remain high and the supply of goods through distribution channels is sufficient, no effect on demand is forecast until 1H23. Nonetheless, it will be a challenge in the long-term. Since the ban expressly prohibits supercomputing center applications such as HPC, TrendForce assesses that GPU servers used by supercomputing centers will be directly affected, which accounts for up to 30% of China’s GPU market.

In terms of chip computing performance control, ECCNs 3A090 and 4A090 are newly added sanctioned items and chips with a total processing performance of more than 4,800 (inclusive) calculated by TOPS will be restricted. GPUs are usually used to directly assist in performing complex operations. Basically, NVIDIA’s A100 PCIe Gen4 and AMD’s MI250 OAM Module exceed the 4,800 limit. With new high computing performance products restricted in the future, development of server acceleration computing in China will take a hit.

However, the computing performance of most server CPU products is generally lower than the provisions of the ban. Only Chinese-made chips such as Tianjin Haiguang face direct restrictions and other CPUs such as Intel and AMD servers will not be subject to prohibition. At this stage, Intel and AMD will sign MOUs with relevant mainland Chinese manufacturers to ensure that related products cannot be used in military and supercomputing fields before shipment. In today’s server CPUs, the computing performance of the commonly used Intel Ice Lake CPU series does not reach the limit imposed by U.S. sanctions.

Impact analysis on the memory sector

At present, Samsung and SK hynix have also suspended their supply of product to Sugon. If Sugon can clarify procured memory is not used for supercomputing, domestic server products, etc., the parties will be able to reach a consensus for shipment. In the long run, Korean companies are evaluating whether they need a written commitment from each customer to disavow using purchasing memory products in supercomputers. Therefore, some memory shipments may be affected before documents are signed. The industry generally believes that market inventory remains relatively abundant and there will be no substantial damage to the market in the short term. As far as SSD is concerned, the greatest utilization remains in the category of AI/DL (Deep Learning), since most of the data trained from DL must be stored in faster and more convenient SSDs for use in inference scenarios. If the suspension of shipments caused by the current ban cannot be rectified by relevant buyer agreements, the development of Chinese server manufacturers in related AI/DL fields may be hamstrung and a calamitous decline in the market penetration rate of enterprise SSDs from international manufacturers cannot be ruled out.

Impact analysis on the networking sector

There are three reasons for a relatively minor impact assessment on the well-connected suppliers in the networking sector. First, there are numerous networking suppliers and many of them are in China. Since the demand for key components is relatively small, Chinese suppliers should be able to keep up. Second, the mainstream process in this field is a mature process and future expansion is less restricted. Third, from the perspective of supplier shipments, after foundry assembly, packaging, and testing, there are multiple distribution channels for the circulation of the final product and it will be difficult to determine whether terminals are military use. However, from the perspective of long-term impact, there is a high probability that Chinese manufacturers will give priority to China’s local supply chain in the future to ensure future supply. This move will undoubtedly deepen the resistance of other suppliers’ shipments to China, so it is necessary to open up multiple shipping channels to stabilize market share.
