Common questions
AMD Instinct MI325X vs Tenstorrent Wormhole: which is faster for training?
AMD Instinct MI325X has 17.66x the dense FP16/BF16 throughput of the other (AMD Instinct MI325X: 2,614 TFLOPS; Tenstorrent Wormhole: 148 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 Tenstorrent Wormhole: which has more memory?
AMD Instinct MI325X carries more HBM (AMD Instinct MI325X: 256 GB HBM3e; Tenstorrent Wormhole: 12 GB GDDR6). Memory capacity sets the largest model that fits on one chip without partitioning; memory bandwidth sets inference throughput.
AMD Instinct MI325X vs Tenstorrent Wormhole: which is more power-efficient?
Dense FP16/BF16 TFLOPS per watt: AMD Instinct MI325X 2.61 (2,614 ÷ 1000 W); Tenstorrent Wormhole 0.93 (148 ÷ 160 W). AMD Instinct MI325X wins at the die level; system-level efficiency also depends on cooling and interconnect.
