At this year’s Qualcomm Snapdragon Summit, the company announced its latest PC processor, the Snapdragon X Elite. With impressive performance metrics, this development is poised to shake up the PC processor market as Arm architecture gains ground, posing a substantial challenge to the established x86 architecture.

At this year’s Qualcomm Snapdragon Summit, the company announced its latest PC processor, the Snapdragon X Elite. The launch of laptops featuring the Qualcomm Snapdragon X Elite is expected in mid-2024, marking an opportune moment for a “counteroffensive.”

TrendForce indicates that Arm architecture PC processors have secured around an 11% market share this year, primarily propped up by Apple’s laptop processors. Industry insiders reveal that, in light of the growth potential in the PC processor market, semiconductor giants are increasingly adopting ARM architecture to venture into the market.

2024 Sees Laptop Upgrade Surge, Desktop Market Shrinks                  

Statistics reveal that the surge in remote work during 2020 prompted a shift in consumer preferences from desktop computers to laptops. Moreover, the ongoing establishment of cloud platforms by businesses in 2021 and 2022 has generated positive momentum, signaling a shrinking desktop market and an expanding PC market.

AI-powered PCs and Windows 12 next year are expected to ride a fresh wave of upgrades in 2024. Therefore, when PCs featuring ARM architecture become widespread, Intel and AMD may not be predominantly affected in the laptop processor business based on the x86 architecture. Instead, the desktop processor segment could face the most significant impact.

Kedar Kondap, Qualcomm’s Senior Vice President and General Manager of the Compute and Games Division, foresees an upgrade wave fueled by AI PCs next year, with further growth anticipated in 2025. It is expected that consumers will lean towards AI PCs for their next computer purchases.

The initial wave of products equipped with Qualcomm’s AI PC processors has been unveiled, aligning with the upcoming wave of device upgrades in next year. While Intel is set to launch its first AI acceleration engine, the Intel Core Ultra, featuring integrated NPU in December, its Microsoft Windows 12 certification remains a point of observation.

In a broader perspective, Intel and AMD are positioned to follow up with the AI PC trend by 2025. This coincides with the ending service of Windows 10 and the gradual implementation of Wifi 7 and 6G technologies. By 2028, they are expected to play a pivotal role in driving AI PC growth.

On another note, a South Korean analyst anticipates that the growth momentum in AI PCs hinges on when Apple incorporates AI features into Mac computers.

ARM vs. x86, Microsoft’s Crucial Role                                    

This is because Microsoft is set to launch Windows 12 next year, featuring the built-in Copilot AI assistant. It will collaborate with operating systems and software such as Windows, Edge, Microsoft 365, Outlook, and the Bing search engine, ushering in an entirely new AI-driven user experience.

Several tech giants are fiercely competing in the AI PC market, with NVIDIA and AMD investing in the development of Arm architecture processors. It’s worth mentioning that in 2016, Microsoft agreed to let Qualcomm exclusively develop Windows-compatible chips, and this agreement is set to expire in 2024. Consequently, Qualcomm may gain a strategic advantage. In contrast, the collaboration between NVIDIA and MediaTek on Arm processors might only begin to bear fruit in 2025.

As for AMD’s foray into Arm architecture research and development, whether this indicates a less optimistic outlook for the x86 market is a matter for ongoing observation. Intel CEO Pat Gelsinger expressed that he isn’t concerned about Arm architecture processors vying in the PC market. From a different perspective, Intel may even consider assisting with manufacturing.

According to TrendForce research, corporate demand for digital transformation including artificial intelligence and high-performance computing has accelerated in recent years, which has led to increasing adoption of cloud computing. In order to improve service flexibility, the world’s major cloud service providers have gradually introduced ARM-based servers. The penetration rate of ARM architecture in data center servers is expected to reach 22% by 2025.

In the past few years, ARM architecture processors have matured in the fields of mobile terminals and Internet of Things but progress in the server field has been relatively slow. However, companies have diversified cloud workloads in recent years and the market has begun to pay attention to the benefits ARM architecture processing can provide to data centers. TrendForce believes that ARM-based processors have three major advantages. First, they can support diverse and rapidly changing workloads and are more scalability and cost-effective. Second, ARM-based processors provide higher customization for different niche markets with a more flexible ecosystem. Third, physical footprint is relatively small which meets the needs of today’s micro data centers.

Influenced by geopolitics and the strengthening of data sovereignty in various countries, major cloud service providers and telecom operators are actively developing micro data centers which will further drive the penetration of ARM-based processors. At the same time, from the perspective of cloud service providers currently adopting ARM-based processors, Graviton, led by AWS, has the largest market scale and began encroaching gradually into the market in 2021. TrendForce also observed that AWS’s deployment of ARM-based processors in 2021 reached 15% of overall server deployment and will exceed 20% in 2022. This forces other major cloud service providers to keep up by initiating their own projects at various foundries. If testing is successful, these projects are expected to start mass introduction in 2025.

In addition, according to the Neoverse Platform plan previously released by ARM, its Platform Roadmap will also be one of the key drivers of penetration. This product line is set up to target ultra-large-scale data centers and edge computing infrastructure. However, it is worth mentioning, since x86 is still mainstream in the market and ARM-based server CPU suppliers only maintain small-batch production orders at this stage and primarily focus on ultra-large-scale data centers, introduction of ARM-based servers into enterprise data centers will be slow going. Thus, TrendForce believes that it will still be difficult for ARM-based servers to compete with x86-based servers before 2025.

While the server industry transitions to the latest generation of processors based on the x86 platform, the Intel Ice Lake and AMD Milan CPUs entered mass production earlier this year and were shipped to certain customers, such as North American CSPs and telecommunication companies, at a low volume in 1Q21, according to TrendForce’s latest investigations.

These processors are expected to begin seeing widespread adoption in the server market in 3Q21. TrendForce believes that Ice Lake represents a step-up in computing performance from the previous generation due to its higher scalability and support for more memory channels. On the other hand, the new normal that emerged in the post-pandemic era is expected to drive clients in the server sector to partially migrate to the Ice Lake platform, whose share in the server market is expected to surpass 30% in 4Q21.

Volume ramp of CPUs based on the Eagle Stream platform will likely take place in 2Q22, while AMD is expected to reach a 15% share in the server market next year

Regarding the mass production schedule of Intel CPUs based on the next-gen Eagle Stream platform, volume ramp is expected to occur in 2Q22. These processors, which feature embedded HBM, comprise a much more diverse product lineup compared to the previous generation. Although Intel’s 2Q22 target represents a slight delay from the market’s previous expectation of a 4Q21 ramp-up, Eagle Stream CPUs will enter the final product qualification stage at the end of 4Q21, after which Intel will begin provisioning certain leading customers with a small batch of these CPUs in 1Q22, according to TrendForce’s survey of server ODMs. As such, the mass production schedule of Sapphire Rapids will likely resemble the release of Ice Lake server processors earlier this year.

Genoa CPUs, AMD’s competitive equivalent of the Intel Eagle Stream, are expected to enter mass production on a similar schedule, since AMD’s wafer starts at the 5nm node have been relatively low-volume. AMD’s server processors manufactured at the 14nm node and below have the competitive advantage in terms of price-to-performance, core count, and interface support.

Furthermore, after progressing to the 7nm node, these processors have been seeing gradually increased adoption by various public cloud service providers, including Google Cloud Platform, Microsoft Azure, and Tencent, throughout 2021. AMD CPUs have currently surpassed a 10% penetration rate in these three CSPs’ servers. Going forward, AMD will begin inputting wafers at the 5nm node at the end of 2021 in order to further optimize its processors’ cost, power consumption, and performance. TrendForce therefore expects AMD CPUs to reach a 15% share in the global server market in 2022.

While the ARM architecture is starting to gain popularity, ARM chips are mostly built-to-order due to the relatively small scale of client demand

Processors based on the ARM architecture began seeing increased market penetration this year, with AWS’ self-designed Graviton chips enjoying the greatest market share. In addition, Ampere and Marvell have also been releasing more agile and flexible ARM-based server processors, validation for which by CSPs is expected to kick off in 4Q21. The server market, however, is still dominated by x86 processors, which currently account for 97% of total server processor shipments.

In particular, AMD has transitioned most of its server offerings to processors manufactured at the 7nm and 7nm+ nodes by increasing wafer inputs at these nodes and replacing its old 14nm product lineups. This transition has paid off, as some of AMD’s clients have gradually become receptive to these new products. On the other hand, ARM- and RISC-based processors are currently built to order, mostly for the data center market. TrendForce therefore believes that ARM CPUs will not be competitive with x86 CPUs in the server market before 2023.

Support will extend to include PCIe G5 and DDR5 RDIMM, while CXL will improve memory performance

It should be noted that Intel as the dominant leader in the market for x86 server CPUs has decided to have Eagle Stream support CXL (Compute Express Link). This interface further optimizes the memory coherence between the CPU and the memory components to which the CPU is connected. The processor platform thus has the ultimate function of establishing a memory pool for all computing units within the server through memory virtualization, even though this function is not notably emphasized in the initial establishment of the product specifications, which originally sought to enable high-bandwidth and low-latency data transfer for the CPU.

The memory pool, in turn, enhances the interconnections (or the data transfer efficiency) among the CPU, memory, GPU, ASIC, FPGA, etc. The new CXL interface will be able to offer significant improvements in terms of dealing with heavier workload in the future and conducting heterogeneous computing. Moreover, CXL will be able to overcome the limits imposed on the current hardware architecture with respect to data transfer and thereby enable more effective integrated computing capability.

The build-out of data centers continues to grow because of the emergence of applications related to AI and Big Data. Furthermore, the demand for larger cloud storage capacity has massively expanded as a result of enterprises’ increasingly rapid digital transformation efforts in the post-pandemic world. At the same time, with the increase in CPU core count, how to raise computing performance via memory optimization has now become an important issue. Eagle Stream can resolve this bottleneck by extending support to PCIe G5 for the SSD interface technology.

Compared with its predecessor, PCIe G5 offers twice the data transfer rate. Therefore, hyperscalers are eager to adopt SSDs based on this standard. As for DRAM, both Eagle Stream and Genoa extend support to the next-generation DDR5 server DRAM, which delivers a faster data transfer rate, making these new server CPUs superior to Ice Lake in all respects. NAND Flash and DRAM suppliers have made plans to commence mass production of PCIe G5 SSDs and DDR5 RDIMMs at the end of 2Q22 in anticipation of demand generated by the release of the Eagle Stream and Genoa platforms for these next-gen products.
