Huawei Warns Nvidia and Others of Looming Chip Manufacturing Limits

Huawei's top semiconductor scientist, Liao Heng, has warned that Western chipmaking giants, including Nvidia, will soon face physical limits in their pursuit of more powerful processors. In a rare public appearance, Liao explained that the decades-long practice of continually shrinking and making integrated circuits more dense is reaching its end.

Liao pointed out that companies like Nvidia are building ever-larger chips with billions of transistors and increasing amounts of high-bandwidth memory (HBM) attached. However, he noted that there will be a limit to how much they can scale up before hitting a physical barrier.

The industry is still pushing the boundaries, but once it crosses this limit, Liao believes there will be an 'avalanche' effect. Huawei, on the other hand, has developed its own Tau Scaling Law, which proposes focusing on improving transmission speeds between parts in a computer system rather than shrinking chips.

Liao emphasized that China is hardening its resolve to wean itself off Western technology and become self-sufficient in semiconductor manufacturing. He praised Huawei's novel approach and highlighted the company's efforts to develop its own AI chips, which will better support efficiency-focused model architectures through a co-design mechanism.
