Common questions
NVIDIA L40S vs Tenstorrent Wormhole: which is faster for training?
NVIDIA L40S has 4.95x the dense FP16/BF16 throughput of the other (NVIDIA L40S: 733 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.
NVIDIA L40S vs Tenstorrent Wormhole: which has more memory?
NVIDIA L40S carries more HBM (NVIDIA L40S: 48 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.
NVIDIA L40S vs Tenstorrent Wormhole: which is more power-efficient?
Dense FP16/BF16 TFLOPS per watt: NVIDIA L40S 2.09 (733 ÷ 350 W); Tenstorrent Wormhole 0.93 (148 ÷ 160 W). NVIDIA L40S wins at the die level; system-level efficiency also depends on cooling and interconnect.
