So about 5 years behind the cutting edge, SMIC showed their advanced lithography tools today(still no ASML) but come 2030 at this rate? Hard to say they won’t catch up.

While their lithography may lag, their system-level engineering is leveraging unique strengths. China's lack of power constraints allows them to build massive, optically-networked systems like the CloudMatrix 384. There is a SemiAnalysis that compares it to Nvidia’s GB200 NVL72. It looks like they overcome weaker individual chips to outperform Nvidia’s GB200 NVL72 with 2x the compute, 3.6x the aggregate memory, and 2.1x the memory bandwidth. with scale-out networking and software optimization, not just silicon.

The A100 gpu is almost 5 years old at this point, and still useful for a lot of things.
