flag Huawei's new AI chip uses pre-sanction components from Taiwan and South Korea, despite U.S. restrictions.

flag Huawei’s latest Ascend 910C AI chips, promoted as a milestone in China’s tech self-reliance, rely on critical components from Taiwan Semiconductor, Samsung, and SK Hynix, according to a TechInsights teardown. flag Though U.S. sanctions have blocked Huawei’s access to advanced chips since 2020, the company used stockpiled TSMC processor dies and older HBM2E memory from Samsung and SK Hynix, likely acquired via intermediary Sophgo. flag TSMC, Samsung, and SK Hynix confirm they ceased sales to Huawei after 2020, but components in the 910C chips suggest pre-sanction inventory remains in use. flag Huawei is advancing AI ambitions with a new interconnect system claiming high-speed data transfer, but analysts note its chips still lag behind Nvidia in performance and use older 7-nanometer technology, highlighting ongoing supply chain vulnerabilities.
