Common questions
AMD Instinct MI300X vs Google TPU v7 (Ironwood): which is faster for training?
Google TPU v7 (Ironwood) has 3.53x the dense FP8 throughput of the other (AMD Instinct MI300X: 2,614 TFLOPS; Google TPU v7 (Ironwood): 9,228 TFLOPS). Real-world training speed also depends on memory bandwidth, interconnect, and software stack: see the spec diff for those inputs.
AMD Instinct MI300X vs Google TPU v7 (Ironwood): which has more memory?
Google TPU v7 (Ironwood) carries more HBM (AMD Instinct MI300X: 192 GB HBM3; Google TPU v7 (Ironwood): 192 GB HBM3e). Memory capacity sets the largest model that fits on one chip without partitioning; memory bandwidth sets inference throughput.
AMD Instinct MI300X vs Google TPU v7 (Ironwood): which is more power-efficient?
Dense FP8 TFLOPS per watt: AMD Instinct MI300X 3.49 (2,614 ÷ 750 W); Google TPU v7 (Ironwood) 13.18 (9,228 ÷ 700 W). Google TPU v7 (Ironwood) wins at the die level; system-level efficiency also depends on cooling and interconnect.
