US moves to block Nvidia AI chips from reaching Chinese firms overseas - digitimes

The US Commerce Department is taking action to close a potential export-control loophole that may have enabled Chinese technology companies to obtain advanced AI chips, including Nvidia's Blackwell pr... Read original →

The U.S. move to block Chinese firms from accessing NVIDIA’s Blackwell chips via overseas subsidiaries marks a shift from product-based to end-user-centric export controls. Technically, this forces Chinese AI developers toward customized architectures on mature nodes (7nm+), degrading large-model training efficiency. TSMC and other foundries now face intensified scrutiny over end-use, risking geopolitical interference in 3nm/EUV capacity allocation. Compliance costs will surge, fragmenting global distribution into regional silos. In the short term, Huawei Ascend and Cambricon may gain domestic share, yet performance gaps persist. Over the next 12–24 months, China will accelerate investments in chiplet integration and in-memory computing as workarounds, while laying groundwork for a domestic EUV ecosystem. This won’t halt China’s semiconductor ascent—but it will substantially delay its high-end AI chip commercialization timeline.
