Common questions
Google TPU v7 (Ironwood) vs Huawei Ascend 910D: which is faster for training?
Google TPU v7 (Ironwood) has 3.85x the dense FP8 throughput of the other (Google TPU v7 (Ironwood): 9,228 TFLOPS; Huawei Ascend 910D: 2,400 TFLOPS). Real-world training speed also depends on memory bandwidth, interconnect, and software stack: see the spec diff for those inputs.
Google TPU v7 (Ironwood) vs Huawei Ascend 910D: which has more memory?
Huawei Ascend 910D carries more HBM (Google TPU v7 (Ironwood): 192 GB HBM3e; Huawei Ascend 910D: 192 GB HBM3). Memory capacity sets the largest model that fits on one chip without partitioning; memory bandwidth sets inference throughput.
Google TPU v7 (Ironwood) vs Huawei Ascend 910D: which is more power-efficient?
Dense FP8 TFLOPS per watt: Google TPU v7 (Ironwood) 13.18 (9,228 ÷ 700 W); Huawei Ascend 910D 3.00 (2,400 ÷ 800 W). Google TPU v7 (Ironwood) wins at the die level; system-level efficiency also depends on cooling and interconnect.
