Beijing is pushing Chinese companies to develop AI using locally made chips instead of relying on US-made Nvidia products.
Several regulatory bodies, including the Ministry of Industry and Information Technology, have issued unofficial "window guidance" in recent months, according to Bloomberg sources. These non-binding directives aim to reduce Nvidia chip usage and promote domestic suppliers like Huawei and Cambricon.
The informal guidance is aimed at boosting the market share of Chinese AI chipmakers while preparing for possible further US restrictions. However, Beijing is keen to avoid hampering AI start-ups or escalating tensions with the US.
Some companies are ignoring the unofficial advice and continuing to buy Nvidia chips, stockpiling ahead of expected US sanctions later this year. To appease officials, they're also buying domestic Huawei chips in parallel.
Nvidia is already lurking with Blackwell
Huawei is currently showcasing its new Ascend 910C chip, an upgrade to the 910B model, which reportedly matches Nvidia's A100 in performance. Due to US restrictions, Nvidia can only sell an inferior H20 chip in China.
However, Huawei and other Chinese firms face an uphill battle. Nvidia recently unveiled its Blackwell architecture at GTC 2024, designed for large language models with trillions of parameters.
Compared to the H100, Blackwell claims four times higher training performance, up to 25 times better energy efficiency, and up to 30 times faster inference. In the MLPerf Inference v4.1 benchmark with Llama 2 70B, Blackwell shows up to four times more performance per GPU than the H100, partly due to new FP4 precision.
