TechInsights discovered that Huawei’s AI accelerators still contain chips manufactured by Taiwan Semiconductor Manufacturing Company (TSMC), raising concerns amid US trade restrictions. The investigation found that one of Huawei’s AI accelerators features an Ascend 910B chip, reportedly made by TSMC, despite the company's claims of no dealings with Huawei since 2020. TSMC notified the US Commerce Department about a suspicious order related to the Huawei chip and contacted the customer involved.
