Common questions
AMD Instinct MI300X vs AMD Instinct MI350 series: which is faster for training?
AMD Instinct MI350 series has 1.76x the dense FP8 throughput of the other (AMD Instinct MI300X: 2,614 TFLOPS; AMD Instinct MI350 series: 4,600 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 MI350 series: which has more memory?
AMD Instinct MI350 series carries more HBM (AMD Instinct MI300X: 192 GB HBM3; AMD Instinct MI350 series: 288 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 MI350 series: which is more power-efficient?
Dense FP8 TFLOPS per watt: AMD Instinct MI300X 3.49 (2,614 ÷ 750 W); AMD Instinct MI350 series 4.60 (4,600 ÷ 1000 W). AMD Instinct MI350 series wins at the die level; system-level efficiency also depends on cooling and interconnect.
AMD Instinct MI300X vs AMD Instinct MI350 series: which is more widely used?
AMD Instinct MI300X: 0 robots and 0 data centers publicly running it. AMD Instinct MI350 series: 0 robots and 1 data center. Empty here means no operator has said publicly, not zero adoption in the market.
