Common questions
Tenstorrent Blackhole vs Tenstorrent Wormhole: which is faster for training?
Tenstorrent Blackhole has 5.03x the dense FP16/BF16 throughput of the other (Tenstorrent Blackhole: 745 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.
Tenstorrent Blackhole vs Tenstorrent Wormhole: which has more memory?
Tenstorrent Blackhole carries more HBM (Tenstorrent Blackhole: 32 GB GDDR6; Tenstorrent Wormhole: 12 GB GDDR6). Memory capacity sets the largest model that fits on one chip without partitioning; memory bandwidth sets inference throughput.
Tenstorrent Blackhole vs Tenstorrent Wormhole: which is more power-efficient?
Dense FP16/BF16 TFLOPS per watt: Tenstorrent Blackhole 2.48 (745 ÷ 300 W); Tenstorrent Wormhole 0.93 (148 ÷ 160 W). Tenstorrent Blackhole wins at the die level; system-level efficiency also depends on cooling and interconnect.
