AMD Radeon PRO W6800 32GB
Overview
The Radeon PRO W6800 is AMD's RDNA 2 workstation flagship: the 60 compute unit Navi 21 die, the same silicon as the Radeon RX 6800, but clocked higher, fitted with 32 GB of ECC GDDR6 and rated at 250 W with a full 128 MB of Infinity Cache. Two things make it interesting beyond CAD work. First, it is the only card in the entire Radeon PRO W line for which AMD publishes a double precision figure, 1.11 TFLOPS, one sixteenth of its 17.8 TFLOPS FP32. Second, 32 GB of ECC memory in a 250 W dual-slot card remains a rare combination on the used market. What it does not have is matrix hardware: RDNA 2 carries none, so the quoted 35.7 TFLOPS FP16 is packed vector throughput and there is no BF16, FP8, INT8 or INT4 rate to compare against a tensor-core part.

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 250 W board power. Where only a sparse figure exists, the cell says so.
