Chip comparison
AMD Instinct MI350 series vs AWS Inferentia 2
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 AWS Inferentia 2: which is faster for training?
AMD Instinct MI350 series has 12.11x the dense FP8 throughput of the other (AMD Instinct MI350 series: 4,600 TFLOPS; AWS Inferentia 2: 380 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 AWS Inferentia 2: which has more memory?
AMD Instinct MI350 series carries more HBM (AMD Instinct MI350 series: 288 GB HBM3e; AWS Inferentia 2: 32 GB HBM3). Memory capacity sets the largest model that fits on one chip without partitioning; memory bandwidth sets inference throughput.
AMD Instinct MI350 series vs AWS Inferentia 2: which is more power-efficient?
Dense FP8 TFLOPS per watt: AMD Instinct MI350 series 4.60 (4,600 ÷ 1000 W); AWS Inferentia 2 1.52 (380 ÷ 250 W). AMD Instinct MI350 series wins at the die level; system-level efficiency also depends on cooling and interconnect.
AMD Instinct MI350 series vs AWS Inferentia 2: which is more widely used?
AMD Instinct MI350 series: 0 robots and 1 data center publicly running it. AWS Inferentia 2: 0 robots and 0 data centers. Empty here means no operator has said publicly, not zero adoption in the market.
