Huawei Technologies

Manufacturer

Huawei is a leading Chinese technology giant specializing in telecommunications, smartphones, networking equipment, and AI solutions. The company is actively developing its own GPUs and AI accelerators in response to US sanctions limiting access to NVIDIA technologies. Main Directions Huawei focuses on the Ascend chip series, such as Ascend 910C and 910D, positioned as alternatives to NVIDIA H100 and Blackwell. These accelerators are manufactured using SMIC's 7-nm process and are used in supercomputers like CloudMatrix 384 with 384 chips, providing up to 300 petaflops in BF16—almost twice as much as NVIDIA GB200 NVL72. The systems stand out with large memory capacity (up to 49.2 TB HBM, 3.6 times more than NVIDIA analogs) and high bandwidth (1229 TB/s). GPU Developments In 2025, Huawei shifted from specialized ASICs to universal GPUs with CUDA compatibility via an intermediate layer that converts NVIDIA code into commands for its chips. This reduces dependence on embargoes and simplifies migration for developers; conversion efficiency exceeds 95%. Plans include producing 600,000 accelerators in 2026, including Ascend 910D (4 chips in one) and 950DT. Technologies and Optimization Huawei's software masks differences between its chips and NVIDIA GPUs, doubling the utilization rate from 35% to 70% in AI clusters. Ascend 910C achieves 320–800 TFLOPS in FP16 at 310 W, though it lags behind NVIDIA in energy efficiency due to the process technology. In mobile devices, GPU Turbo is used to accelerate graphics by 60%.
