Chip comparison
AMD Instinct MI350 series 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
AMD Instinct MI350 series vs NVIDIA L40S: which is faster for training?
AMD Instinct MI350 series has 6.28x the dense FP8 throughput of the other (AMD Instinct MI350 series: 4,600 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.
AMD Instinct MI350 series vs NVIDIA L40S: which has more memory?
AMD Instinct MI350 series carries more HBM (AMD Instinct MI350 series: 288 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.
AMD Instinct MI350 series vs NVIDIA L40S: which is more power-efficient?
Dense FP8 TFLOPS per watt: AMD Instinct MI350 series 4.60 (4,600 ÷ 1000 W); NVIDIA L40S 2.09 (733 ÷ 350 W). AMD Instinct MI350 series wins at the die level; system-level efficiency also depends on cooling and interconnect.
AMD Instinct MI350 series vs NVIDIA L40S: which is more widely used?
AMD Instinct MI350 series: 0 robots and 1 data center 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.
