AMD Instinct MI300X Platform
AMD's eight-GPU building block for CDNA 3, integrating eight MI300X OAM modules on an industry-standard OCP universal baseboard (UBB 2.0), each linked to the other seven over 128 GB/s Infinity Fabric links for 896 GB/s of aggregate ring bandwidth, plus one PCIe Gen 5 x16 host link per GPU. AMD's platform datasheet gives 1.5 TB of HBM3 (stored as 8 x 192 GB = 1.536 TB) and 5.3 TB/s per GPU, so 42.4 TB/s across the board, with a 750 W maximum board power per GPU (6.0 kW for the eight GPUs, not counting the host). Compute: 2,432 compute units, 155,648 stream processors at up to 2,100 MHz. AMD sells it through solution partners rather than directly. Precision figures are eight times the per-GPU MI300X row, which AMD's one-decimal platform figures round, except FP32 and FP64, where AMD's platform figures are printed more precisely and are stored as printed.

Where a vendor states a basis, the figure shown is the dense one, and any figure it publishes is listed separately. Vendors commonly headline the sparse number instead: for NVIDIA's 2:4 structured sparsity that is exactly twice the dense figure, though other vendors' sparse modes do not all follow that ratio.
