Intel’s upcoming Lunar Lake platform has entrusted TSMC with the 3nm process of its CPU. This marks TSMC’s debut as the exclusive producer for Intel’s mainstream laptop CPU, including the previously negotiated Lunar Lake GPU and high-speed I/O (PCH) chip collaborations. This move positions TSMC to handle all major chip orders for Intel’s crucial platform next year, reported by UDN News.

Regarding this news, TSMC refrained from commenting on single customer business or market speculations on November 21st. Intel has not issued any statements either.

Recent leaks of Lunar Lake platform internal design details from Intel have generated discussions on various foreign tech websites and among tech experts on X (formerly known as Twitter). According to the leaked information, TSMC will be responsible for producing three key chips for Intel’s Lunar Lake—CPU, GPU, and NPU—all manufactured using the 3nm process. Orders for high-speed I/O chips are expected to leverage TSMC’s 5nm production, with mass production set to kick off in the first half of next year, aligning with the anticipated resurgence of the PC market in the latter half of the year.

While TSMC previously manufactured CPUs for Intel’s Atom platform over a decade ago, it’s crucial to note that the Atom platform was categorized as a series of ultra-low-voltage processors, not Intel’s mainstream laptop platform. In recent years, Intel has gradually outsourced internal chips, beyond CPUs, for mainstream platforms to TSMC, including the GPU and high-speed I/O chips in the earlier Meteor Lake platform—all manufactured using TSMC’s 5nm node.

Breaking from its tradition of in-house production of mainstream platform CPUs, Intel’s decision to outsource to TSMC hints at potential future collaborations. This move opens doors to new opportunities for TSMC to handle the production of Intel’s mainstream laptop platforms.

It’s worth noting that the Intel Lunar Lake platform is scheduled for mass production at TSMC in the first half of next year, with a launch planned for the latter half of the year, targeting mainstream laptop platforms. Unlike the previous two generations of Intel laptop platforms, Lunar Lake integrates CPU, GPU, and NPU into a system-on-chip (SoC). This SoC is then combined with a high-speed I/O chip, utilizing Intel’s Foveros advanced packaging. Finally, the DRAM LPDDR5x is integrated with the two advanced packaged chips on the same IC substrate.

According to the latest report from TrendForce, the primary factors influencing the global market share of notebook CPUs in 2024 can be categorized into “Architectural Design” and “Economic Factors.”

“Architectural Design” as a long-term factor affecting market share:

(1) Both AMD (AMD 3D V-Cache) and Intel (Intel Foveros Direct) may potentially integrate 3D packaging technology into notebook computers in the future.

(2) Apple’s M-series processors, using the Arm core architecture, as well as Intel processors, have adopted a big/little core hybrid design. AMD might also introduce this in the Ryzen 8000 series.

(3) Despite further advancements in processor technology by 2024, the notebook computer market remains highly sensitive to the cost for IT equipment.

“Economic Factors” as more immediate influencers of market share:

(1) Until 2024, a return to lower interest rates in the global economic environment could favor corporate expansion of capital expenditure. This could result in increased procurement of business-oriented notebook models, potentially allowing Intel to further expand its CPU market share beyond 70% in the business sector.

(2) Concerns about economic prospects among global citizens until 2024 could have significant negative implications for the consumer notebook computer market. With the restart of physical economic activities, the demand for consumer-oriented notebook models has declined from the high levels seen during the pandemic. Consequently, the consumer market demand outlook for 2024 remains uncertain. For AMD, which relies more on consumer market demand, changes in market share may be harder to predict compared to Intel.

In the post-pandemic era, AMD, Arm/Apple, and Intel are pursuing distinct technological competition strategies to capture market share in the personal computing market.

AMD:

(1) The Socket AM5 platform is poised to aid AMD CPUs in achieving substantial performance and efficiency gains.

(2) The AMD Ryzen 7040 incorporates an artificial intelligence engine to emphasize AI computing performance’s importance in the thin and light notebook market.

Arm/Apple:

(1) The M2 Ultra processor heralds Apple’s complete transition of personal computing products to the Arm core. Apple Mac computer products will no longer be sold with Intel processor.

(2) The Apple M-series processors, built on the Arm core architecture, facilitate a “fanless design” to maintain MacBook’s slim profile. This feature highlights its irreplaceable positioning in the portable notebook computer market, emphasizing portability.

Intel:

(1) With the waning trend of the “hybrid work mode,” Intel is optimistic about diversified development in the post-pandemic era for desktop computer products. This includes microcomputers, micro workstations, and general workstations. Due to the characteristic of continuous operation for 24 hours, desktop computers still possess unique attributes that cannot be replaced by notebook computers.

NVIDIA’s robust financial report reveals the true impact of AI on the technology industry, particularly in the AI server supply chain. …

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.
