AMD Instinct MI300X 8-GPU Server (Supermicro AS-8125GS-TNMR2)
AMD Instinct MI300X 8-GPU server — 1,536 GB HBM3 per node on the Supermicro AS-8125GS-TNMR2 (8U air-cooled) with dual AMD EPYC CPUs.
8-GPU AMD Instinct MI300X server on the Supermicro AS-8125GS-TNMR2 — the 8U air-cooled reference platform. Eight MI300X (CDNA 3) accelerators deliver 192 GB of HBM3 each — 1,536 GB per node — over AMD Infinity Fabric at 896 GB/s peer bandwidth, so a single node holds models that would otherwise span several 80 GB GPUs. Dual AMD EPYC 9004/9005 processors and eight 400 Gb/s scale-out NICs feed the accelerators for training and memory-bound inference. Configuration and availability confirmed at quote.
