AMD Instinct MI325X vs Google TPU v4
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
AMD Instinct MI325X vs Google TPU v4: which is faster for training?
AMD Instinct MI325X has 9.51x the dense FP16/BF16 throughput of the other (AMD Instinct MI325X: 2,614 TFLOPS; Google TPU v4: 275 TFLOPS). Real-world training speed also depends on memory bandwidth, interconnect, and software stack: see the spec diff for those inputs.
AMD Instinct MI325X vs Google TPU v4: which has more memory?
AMD Instinct MI325X carries more HBM (AMD Instinct MI325X: 256 GB HBM3e; Google TPU v4: 32 GB HBM2). Memory capacity sets the largest model that fits on one chip without partitioning; memory bandwidth sets inference throughput.
AMD Instinct MI325X vs Google TPU v4: which is more power-efficient?
Dense FP16/BF16 TFLOPS per watt: AMD Instinct MI325X 2.61 (2,614 ÷ 1000 W); Google TPU v4 1.43 (275 ÷ 192 W). AMD Instinct MI325X wins at the die level; system-level efficiency also depends on cooling and interconnect.
AMD Instinct MI325X vs Google TPU v4: which is more widely used?
AMD Instinct MI325X: 0 robots and 0 data centers publicly running it. Google TPU v4: 0 robots and 2 data centers. Empty here means no operator has said publicly, not zero adoption in the market.
