Before then, TSMC supplied chips for Huawei's Ascend series, sources told Reuters earlier this year. Its Ascend 910B, released in 2022, is viewed as the most advanced AI chip available from a Chinese company.
In August, the Research Institute for Democracy, Society and Emergency Technology (DSET) in Taiwan reported that Bitmain, which it described as a leading Chinese integrated circuit design enterprise and supplier of cryptocurrency mining machines, was "aiming to challenge the AI chip market dominance of Nvidia and AMD."
The DSET report described Sophgo as a Bitmain affiliate.
Sophgo was co-founded by Micree Zhan, who also co-founded Bitmain, according to a corporate registration database.
The company also communicated with the U.S. Federal Communications Commission in 2023 using a Bitmain email address and the name Xiamen Sophgo Technologies Ltd.
