Common questions
AWS Trainium (Trn1) vs Tenstorrent Blackhole: which is faster for training?
Tenstorrent Blackhole has 3.55x the dense FP16/BF16 throughput of the other (AWS Trainium (Trn1): 210 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 (Trn1) vs Tenstorrent Blackhole: which has more memory?
Tenstorrent Blackhole carries more HBM (AWS Trainium (Trn1): 32 GB HBM2e; 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 (Trn1) vs Tenstorrent Blackhole: which is more power-efficient?
Dense FP16/BF16 TFLOPS per watt: AWS Trainium (Trn1) 0.42 (210 ÷ 500 W); Tenstorrent Blackhole 2.48 (745 ÷ 300 W). Tenstorrent Blackhole wins at the die level; system-level efficiency also depends on cooling and interconnect.
