Huawei Comeback Tests Limits of US Chip Export Controls
BLUFWhether Huawei can translate its captive Chinese market position into a next-generation accelerator by December 2026 remains genuinely uncertain, with SMIC fabrication constraints outpacing any verified design breakthroughs.
Nvidia CEO Jensen Huang told CNBC in May that Nvidia has "largely conceded" China's AI chip market to Huawei after US export restrictions in April barred advanced chip sales without a license 1. CSET's June 17 technical analysis puts the Ascend 910B's real hardware gain over the first-generation 910 at 60 FP16 TFLOPS, not the advertised 80, with the gap stemming from a change in how Huawei counts peak operations 2. The 910B also fields fewer active AI cores (20-25 vs. 30-32), a reduction CSET attributes to yield or capacity constraints on SMIC's 7nm fabrication process 2. Nikkei Asia reported June 17 that Huawei chip chief He Tingbo has publicly claimed the company developed a new design approach that could eliminate dependence on EUV lithography tools 3.
AnalysisCSET finds the Ascend 910B delivers 60 FP16 TFLOPS above its predecessor, not the claimed 80, with a reduced active-core count (20-25 versus 30-32) pointing to SMIC 7nm yield or capacity constraints that any successor design must navigate. He Tingbo's EUV-bypass claim is unverified and could reflect genuine progress, competitive posturing, or domestic-market signaling. Whether Huawei ships a next-generation accelerator by December 31, 2026 is
genuinely uncertain. Low confidence reflects the absence of production-readiness indicators beyond Huawei's own statements and opacity around SMIC yield rates. The core-count reduction may instead indicate managed yield optimization, leaving SMIC's 7nm capacity better positioned than the constrained-supply reading requires. If a competitive successor ships by year's end, BIS faces a material reassessment of FDPR assumptions. Absent that, the April framework retains near-term adequacy.
