Huawei's Ascend 910C AI chip was positioned as one of the better Chinese-developed alternatives to NVIDIA's H100 accelerator—reports from last autumn suggested that samples were being sent to highly important customers. The likes of Alibaba, Baidu, and Tencent have long relied on Team Green enterprise hardware for all manner of AI crunching, but trade sanctions have severely limited the supply and potency of Western-developed AI chips. NVIDIA's region-specific B20 "Blackwell" accelerator is due for release this year, but industry watchdogs reckon that the Ascend 910C AI GPU is a strong rival. The latest online rumblings have pointed to another major Huawei customer—DeepSeek—having Ascend silicon in their back pockets.

DeepSeek's recent unveiling of its R1 open-source large language model has disrupted international AI markets. A lot of press attention has focused on DeepSeek's CEO stating that his team can access up to 50,000 NVIDIA H100 GPUs, but many have not looked into the company's (alleged) pool of natively-made chips. Yesterday, Alexander Doria—an LLM enthusiast—shared an interesting insight: "I feel this should be a much bigger story—DeepSeek has trained on NVIDIA H800, but is running inference on the new home Chinese chips made by Huawei, the 910C." Experts believe that there will be a plentiful supply of Ascend 910C GPUs—estimates from last September posit that 70,000 chips (worth around $2 billion) were in the mass production pipeline. Additionally, industry whispers suggest that Huawei is already working on a—presumably, even more powerful—successor.

According to a recent Reuters report, TSMC has decided to cut off Chinese firm Sophgo following the discovery of TSMC-manufactured components in Huawei's advanced AI processor. The suspension came after technology research firm TechInsights identified a TSMC-manufactured chip within Huawei's Ascend 910B processor during a detailed analysis. This discovery raised significant concerns, as Huawei has been restricted from accessing such technology under US export controls since 2020. TSMC promptly notified US authorities upon learning of the situation and launched an internal investigation. While being sanctioned by the US, Huawei needed to use a proxy firm to get access to high-end silicon manufacturing to produce its Ascend accelerators.

Sophgo, which has ties to cryptocurrency mining equipment manufacturer Bitmain, strongly denies any business relationship with Huawei. The company states it has provided TSMC with a detailed investigation report asserting its compliance with all applicable laws, saying: "SOPHGO has never been engaged in any direct or indirect business relationship with Huawei. SOPHGO has been conducting business in strict compliance with applicable laws and regulations, including but not limited to all the applicable US national export control laws and regulations, and has never been in violation of any of such laws and regulations. SOPHGO has provided detailed investigation report to TSMC to prove that SOPHGO is not related to the Huawei investigation."
