AMD Instinct MI355X Platform
AMD's eight-GPU building block, integrating eight fully connected MI355X OAM modules on an industry-standard OCP universal baseboard over fourth-generation Infinity Fabric. AMD publishes the platform totals of 2.3 TB of HBM3E and 64 TB/s of aggregate memory bandwidth, both of which are exactly eight times the per-GPU figures, which is why the precision values here are also eight times AMD's published per-GPU specification rather than a separate platform table, since AMD provides none. Sparse figures appear only for the four datatypes where AMD publishes a structured-sparsity number, which are FP8, FP16, BF16 and INT8; AMD gives no sparsity figure for MXFP4 or MXFP6, so neither does this row. Supported in both air-cooled UBB servers and direct liquid cooled platforms. AMD publishes no platform power figure.

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.
