Sources told Reuters that the chipmaker's regulatory disclosure to the Commerce Department followed a discovery by TechInsights Inc., a Canadian market research firm. The firm reportedly analyzed an Ascend 910B and found technology from TSMC. "TSMC is a law-abiding company and we are committed to complying with all applicable rules and regulations, including applicable export controls," the chipmaker said a statement. "In compliance with the regulatory requirements, TSMC has not supplied to Huawei since mid-September 2020." In August, the Wall Street Journal reported that Huawei was gearing up to launch a successor to the Ascend 910B. The upcoming chip will reportedly offer comparable speeds to the H100, a graphics card that Nvidia launched in 2022. The H100 is about three times faster than the A100, the Nvidia chip that the current-generation Ascend 910B is reportedly designed to match in performance. The Journal's sources said that Huawei was planning to launch the new AI chip this month.
