Common questions
AMD Instinct MI300X vs AWS Inferentia 2: which is faster for training?
AMD Instinct MI300X has 6.88x the dense FP8 throughput of the other (AMD Instinct MI300X: 2,614 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 MI300X vs AWS Inferentia 2: which has more memory?
AMD Instinct MI300X carries more HBM (AMD Instinct MI300X: 192 GB HBM3; 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 MI300X vs AWS Inferentia 2: which is more power-efficient?
Dense FP8 TFLOPS per watt: AMD Instinct MI300X 3.49 (2,614 ÷ 750 W); AWS Inferentia 2 1.52 (380 ÷ 250 W). AMD Instinct MI300X wins at the die level; system-level efficiency also depends on cooling and interconnect.
