Common questions
AMD Instinct MI300X vs AMD Instinct MI325X: which is faster for training?
AMD Instinct MI325X has 1.00x the dense FP8 throughput of the other (AMD Instinct MI300X: 2,614 TFLOPS; AMD Instinct MI325X: 2,614 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 AMD Instinct MI325X: which has more memory?
AMD Instinct MI325X carries more HBM (AMD Instinct MI300X: 192 GB HBM3; AMD Instinct MI325X: 256 GB HBM3e). Memory capacity sets the largest model that fits on one chip without partitioning; memory bandwidth sets inference throughput.
AMD Instinct MI300X vs AMD Instinct MI325X: which is more power-efficient?
Dense FP8 TFLOPS per watt: AMD Instinct MI300X 3.49 (2,614 ÷ 750 W); AMD Instinct MI325X 2.61 (2,614 ÷ 1000 W). AMD Instinct MI300X wins at the die level; system-level efficiency also depends on cooling and interconnect.
