AMD Radeon RX Vega 56 8GB
Overview
The Radeon RX Vega 56 is the cut-down Vega 10 part, 56 compute units against the RX Vega 64's 64, with the same 8 GB of HBM2 on the same 2048-bit interface but clocked lower for 410 GB/s and a much friendlier 210 W board power. It sits in this catalog as a tier-three historical entry: 8 GB and 10.5 TFLOPS of FP32 do not make a modern inference card, but it is the efficiency point of the Vega generation and the cheapest way to see what HBM2 bandwidth does for memory-bound work. Vega has no matrix cores, so the 21 TFLOPS FP16 AMD quotes is Rapid Packed Math on the vector units at twice FP32, and there is no BF16, FP8, INT8 or INT4 rate published.

Every figure here is dense. The vendor documents no structured (2:4) sparsity mode for this part, so there is no second number to quote.
Per watt divides the dense figure by the 210 W board power. Where only a sparse figure exists, the cell says so.
