Common questions
AWS Inferentia 2 vs Tenstorrent Wormhole: which is faster for training?
AWS Inferentia 2 has 2.57x the dense FP16/BF16 throughput of the other (AWS Inferentia 2: 380 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.
AWS Inferentia 2 vs Tenstorrent Wormhole: which has more memory?
AWS Inferentia 2 carries more HBM (AWS Inferentia 2: 32 GB HBM3; Tenstorrent Wormhole: 12 GB GDDR6). Memory capacity sets the largest model that fits on one chip without partitioning; memory bandwidth sets inference throughput.
AWS Inferentia 2 vs Tenstorrent Wormhole: which is more power-efficient?
Dense FP16/BF16 TFLOPS per watt: AWS Inferentia 2 1.52 (380 ÷ 250 W); Tenstorrent Wormhole 0.93 (148 ÷ 160 W). AWS Inferentia 2 wins at the die level; system-level efficiency also depends on cooling and interconnect.
