Huawei Ascend (910B/910C)
China's flagship AI accelerator and the core of its Nvidia-alternative stack
Huawei's Ascend 910B and 910C are China's leading AI training/inference accelerators, fabricated by SMIC on 7nm-class process and increasingly using domestic HBM. The 910C pairs two 910B dies for near-H100-class performance and is the compute backbone for the CloudMatrix 384 supernode. Ascend is the linchpin of China's push to replace Nvidia amid export controls.
