Common questions
AWS Trainium 2 vs Tenstorrent Blackhole: which is faster for training?
AWS Trainium 2 has 1.74x the dense FP16/BF16 throughput of the other (AWS Trainium 2: 1,300 TFLOPS; Tenstorrent Blackhole: 745 TFLOPS). Real-world training speed also depends on memory bandwidth, interconnect, and software stack: see the spec diff for those inputs.
AWS Trainium 2 vs Tenstorrent Blackhole: which has more memory?
AWS Trainium 2 carries more HBM (AWS Trainium 2: 96 GB HBM3; Tenstorrent Blackhole: 32 GB GDDR6). Memory capacity sets the largest model that fits on one chip without partitioning; memory bandwidth sets inference throughput.
AWS Trainium 2 vs Tenstorrent Blackhole: which is more power-efficient?
Dense FP16/BF16 TFLOPS per watt: AWS Trainium 2 2.60 (1,300 ÷ 500 W); Tenstorrent Blackhole 2.48 (745 ÷ 300 W). AWS Trainium 2 wins at the die level; system-level efficiency also depends on cooling and interconnect.
AWS Trainium 2 vs Tenstorrent Blackhole: which is more widely used?
AWS Trainium 2: 0 robots and 3 data centers publicly running it. Tenstorrent Blackhole: 0 robots and 0 data centers. Empty here means no operator has said publicly, not zero adoption in the market.
