The Huawei-DeepSeek Symbiosis: Ascend 950PR Benchmarks and DeepSeek's Ascend Kernel Support
SemiAnalysis examines the Huawei-DeepSeek partnership, benchmarking an Ascend 950PR (28 cube cores, 128 GiB HBM) and reviewing DeepSeek's September 30 release of Ascend support for TileLang, DeepGEMM, DeepEP, TileKernels, FlashMLA and DeepSelect. The 950PR reaches 1.6384 TB/s peak HBM bandwidth and beats H100 bandwidth utilization at small message sizes, while its median achieved/attainable compute fraction is 41.5% versus H100's 46.8%; only TileLang is usable so far because the required CANN 9.2.0 was unreleased at writing. The authors argue the software stack is near the frontier even as Huawei hardware trails, and note that most optimizations target supernodes, with vLLM-Ascend still failing out of the box on x86 hosts.
