Chip comparison
Google TPU v4 vs NVIDIA L40S
Side-by-side specs
Straight from each vendor's datasheet. Winner in bold: higher throughput, memory, or transistor count; lower power draw or price. Sparse (2:4) throughput roughly doubles the FP8/INT8 numbers shown.

Common questions
Google TPU v4 vs NVIDIA L40S: which is faster for training?
NVIDIA L40S has 2.67x the dense FP16/BF16 throughput of the other (Google TPU v4: 275 TFLOPS; NVIDIA L40S: 733 TFLOPS). Real-world training speed also depends on memory bandwidth, interconnect, and software stack: see the spec diff for those inputs.
Google TPU v4 vs NVIDIA L40S: which has more memory?
NVIDIA L40S carries more HBM (Google TPU v4: 32 GB HBM2; NVIDIA L40S: 48 GB GDDR6). Memory capacity sets the largest model that fits on one chip without partitioning; memory bandwidth sets inference throughput.
Google TPU v4 vs NVIDIA L40S: which is more power-efficient?
Dense FP16/BF16 TFLOPS per watt: Google TPU v4 1.43 (275 ÷ 192 W); NVIDIA L40S 2.09 (733 ÷ 350 W). NVIDIA L40S wins at the die level; system-level efficiency also depends on cooling and interconnect.
Google TPU v4 vs NVIDIA L40S: which is more widely used?
Google TPU v4: 0 robots and 2 data centers publicly running it. NVIDIA L40S: 0 robots and 0 data centers. Empty here means no operator has said publicly, not zero adoption in the market.
