Common questions
NVIDIA GB200 Grace Blackwell Superchip vs NVIDIA L40S: which is faster for training?
NVIDIA GB200 Grace Blackwell Superchip has 12.28x the dense FP8 throughput of the other (NVIDIA GB200 Grace Blackwell Superchip: 9,000 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.
NVIDIA GB200 Grace Blackwell Superchip vs NVIDIA L40S: which has more memory?
NVIDIA GB200 Grace Blackwell Superchip carries more HBM (NVIDIA GB200 Grace Blackwell Superchip: 384 GB HBM3e; NVIDIA L40S: 48 GB GDDR6). Memory capacity sets the largest model that fits on one chip without partitioning; memory bandwidth sets inference throughput.
NVIDIA GB200 Grace Blackwell Superchip vs NVIDIA L40S: which is more power-efficient?
Dense FP8 TFLOPS per watt: NVIDIA GB200 Grace Blackwell Superchip 3.33 (9,000 ÷ 2700 W); NVIDIA L40S 2.09 (733 ÷ 350 W). NVIDIA GB200 Grace Blackwell Superchip wins at the die level; system-level efficiency also depends on cooling and interconnect.
NVIDIA GB200 Grace Blackwell Superchip vs NVIDIA L40S: which is more widely used?
NVIDIA GB200 Grace Blackwell Superchip: 0 robots and 11 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.
