Chip comparison
Google TPU v4 vs Huawei Ascend 910C
Side-by-side specs
Straight from each vendor's datasheet. Winner in bold: higher throughput, memory, or transistor count; lower power draw or price. Sparse (2:4) throughput roughly doubles the FP8/INT8 numbers shown.

Common questions
Google TPU v4 vs Huawei Ascend 910C: which is faster for training?
Huawei Ascend 910C has 2.91x the dense FP16/BF16 throughput of the other (Google TPU v4: 275 TFLOPS; Huawei Ascend 910C: 800 TFLOPS). Real-world training speed also depends on memory bandwidth, interconnect, and software stack: see the spec diff for those inputs.
Google TPU v4 vs Huawei Ascend 910C: which has more memory?
Huawei Ascend 910C carries more HBM (Google TPU v4: 32 GB HBM2; Huawei Ascend 910C: 128 GB HBM2e). Memory capacity sets the largest model that fits on one chip without partitioning; memory bandwidth sets inference throughput.
Google TPU v4 vs Huawei Ascend 910C: which is more power-efficient?
Dense FP16/BF16 TFLOPS per watt: Google TPU v4 1.43 (275 ÷ 192 W); Huawei Ascend 910C 1.60 (800 ÷ 500 W). Huawei Ascend 910C wins at the die level; system-level efficiency also depends on cooling and interconnect.
Google TPU v4 vs Huawei Ascend 910C: which is more widely used?
Google TPU v4: 0 robots and 2 data centers publicly running it. Huawei Ascend 910C: 0 robots and 0 data centers. Empty here means no operator has said publicly, not zero adoption in the market.
