TSMC Advances Smartphone SoCs to Near 5GHz Frequencies with Cutting-Edge Lithography; Huawei Faces Major Setbacks

Tech giants like Apple, Qualcomm, and MediaTek have significantly benefited from deepening their collaborations with TSMC, the Taiwanese semiconductor leader. This partnership has fostered the development of state-of-the-art smartphone chipsets, achieving unprecedented performance benchmarks that would be challenging without TSMC’s cutting-edge manufacturing processes. By late 2023, we anticipate the inaugural clock speeds of smartphone system-on-chips (SoCs) reaching an impressive 5.00GHz. Unfortunately, Huawei is falling behind in this technological race due to its lack of access to TSMC’s renowned foundry services.

Huawei’s Delayed Adoption of EUV Lithography and Its Impact on Kirin Chipsets

A recent analysis by Kurnal highlights the impressive progress made by Apple, Qualcomm, and MediaTek towards achieving higher clock speeds. For instance, Qualcomm’s Snapdragon 8 Elite Gen 5 already has a default clock speed of 4.61GHz, with anticipation building around the Snapdragon 8 Elite Gen 6 Pro potentially hitting the 5.00GHz mark. Meanwhile, MediaTek’s Dimensity 9600 Pro is positioned to reach similar levels, and Apple’s upcoming A19 Pro performance cores are set to achieve speeds of 4.26GHz. This upward trend significantly enhances performance across both single-threaded and multi-threaded operations, leaving Huawei at a disadvantage.

It is important to note that while Huawei’s Kirin SoC lineup has struggled to match the performance of its competitors, this gap arises primarily due to U. S.trade restrictions that have prohibited any transactions with TSMC since 2019. Despite these setbacks, it could be argued that Huawei should have anticipated the implications of these sanctions on its access to advanced manufacturing technologies. The company would have benefited from adopting a strategy toward self-reliance much sooner, especially in light of China’s evolving capabilities in semiconductor production.

TSMC has allowed smartphone chipset manufacturers to nearly touch the 5.00GHz barrier

Unfortunately for Huawei, its partnership with SMIC has restricted its progress to the 7nm process, as SMIC lacks access to advanced extreme ultraviolet (EUV) lithography equipment, relying instead on older deep ultraviolet (DUV) manufacturing techniques. Although there have been reports of China developing its EUV machinery, the timeline for mass production remains uncertain.

Huawei’s latest SoC, the Kirin 9030, highlights this stagnation, failing to surpass the 3.00GHz clock speed barrier. This serves as a stark reminder of how pivotal a robust foundry partner is to technological advancement in the semiconductor industry. Notably, while Apple, Qualcomm, and MediaTek are racing towards the 5.00GHz goal, they must also contend with the inherent challenges of thermodynamics. Increased clock speeds lead to heightened temperatures and thermal throttling, necessitating innovative cooling solutions.

To address these thermal challenges, companies are implementing advanced cooling technologies, including enhanced vapor chambers, compact active cooling fans, and Heat Pass Block systems. These innovations are crucial for sustaining performance during prolonged use without overheating.
