Common questions
Google TPU v5p vs SambaNova SN40L: which is faster for training?
SambaNova SN40L has 2.72x the dense FP16/BF16 throughput of the other (Google TPU v5p: 459 TFLOPS; SambaNova SN40L: 1,250 TFLOPS). Real-world training speed also depends on memory bandwidth, interconnect, and software stack: see the spec diff for those inputs.
Google TPU v5p vs SambaNova SN40L: which has more memory?
SambaNova SN40L carries more HBM (Google TPU v5p: 95 GB HBM2e; SambaNova SN40L: 1500 GB DDR5 (three-tier: 64 MB SRAM + 64 GB HBM3 + 1.5 TB DDR5)). Memory capacity sets the largest model that fits on one chip without partitioning; memory bandwidth sets inference throughput.
Google TPU v5p vs SambaNova SN40L: which is more power-efficient?
Dense FP16/BF16 TFLOPS per watt: Google TPU v5p 1.53 (459 ÷ 300 W); SambaNova SN40L 1.79 (1,250 ÷ 700 W). SambaNova SN40L wins at the die level; system-level efficiency also depends on cooling and interconnect.
Google TPU v5p vs SambaNova SN40L: which is more widely used?
Google TPU v5p: 0 robots and 1 data center publicly running it. SambaNova SN40L: 0 robots and 0 data centers. Empty here means no operator has said publicly, not zero adoption in the market.
