Common questions
AWS Trainium (Trn1) vs Tenstorrent Wormhole: which is faster for training?
AWS Trainium (Trn1) has 1.42x the dense FP16/BF16 throughput of the other (AWS Trainium (Trn1): 210 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 Trainium (Trn1) vs Tenstorrent Wormhole: which has more memory?
AWS Trainium (Trn1) carries more HBM (AWS Trainium (Trn1): 32 GB HBM2e; Tenstorrent Wormhole: 12 GB GDDR6). Memory capacity sets the largest model that fits on one chip without partitioning; memory bandwidth sets inference throughput.
AWS Trainium (Trn1) vs Tenstorrent Wormhole: which is more power-efficient?
Dense FP16/BF16 TFLOPS per watt: AWS Trainium (Trn1) 0.42 (210 ÷ 500 W); Tenstorrent Wormhole 0.93 (148 ÷ 160 W). Tenstorrent Wormhole wins at the die level; system-level efficiency also depends on cooling and interconnect.
