AMD Instinct MI325X vs Intel Gaudi 3

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 MI325X vs Intel Gaudi 3: which is faster for training?

AMD Instinct MI325X has 1.42x the dense FP8 throughput of the other (AMD Instinct MI325X: 2,614 TFLOPS; Intel Gaudi 3: 1,835 TFLOPS). Real-world training speed also depends on memory bandwidth, interconnect, and software stack: see the spec diff for those inputs.

AMD Instinct MI325X vs Intel Gaudi 3: which has more memory?

AMD Instinct MI325X carries more HBM (AMD Instinct MI325X: 256 GB HBM3e; Intel Gaudi 3: 128 GB HBM2e). Memory capacity sets the largest model that fits on one chip without partitioning; memory bandwidth sets inference throughput.

AMD Instinct MI325X vs Intel Gaudi 3: which is more power-efficient?

Dense FP8 TFLOPS per watt: AMD Instinct MI325X 2.61 (2,614 ÷ 1000 W); Intel Gaudi 3 2.04 (1,835 ÷ 900 W). AMD Instinct MI325X wins at the die level; system-level efficiency also depends on cooling and interconnect.
