Common questions
SambaNova SN40L vs Tenstorrent Wormhole: which is faster for training?
SambaNova SN40L has 8.45x the dense FP16/BF16 throughput of the other (SambaNova SN40L: 1,250 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.
SambaNova SN40L vs Tenstorrent Wormhole: which has more memory?
SambaNova SN40L carries more HBM (SambaNova SN40L: 1500 GB DDR5 (three-tier: 64 MB SRAM + 64 GB HBM3 + 1.5 TB DDR5); Tenstorrent Wormhole: 12 GB GDDR6). Memory capacity sets the largest model that fits on one chip without partitioning; memory bandwidth sets inference throughput.
SambaNova SN40L vs Tenstorrent Wormhole: which is more power-efficient?
Dense FP16/BF16 TFLOPS per watt: SambaNova SN40L 1.79 (1,250 ÷ 700 W); Tenstorrent Wormhole 0.93 (148 ÷ 160 W). SambaNova SN40L wins at the die level; system-level efficiency also depends on cooling and interconnect.
