AMD Radeon RX 6800 16GB
Overview
The Radeon RX 6800 is the 60 compute unit Navi 21 part, the cheapest way into AMD's 16 GB RDNA 2 tier and the lowest power of the Navi 21 trio at 250 W. It keeps the full 128 MB Infinity Cache and the full 256-bit bus at 512 GB/s, giving up only shader count against the RX 6800 XT. It shares its compute unit count with the workstation Radeon PRO W6800, which runs the same die faster and doubles the memory to 32 GB with ECC. RDNA 2 has no matrix cores, so 16.17 TFLOPS FP32 and a packed 32.33 TFLOPS FP16 are the entire published ladder, with no BF16, FP8, INT8 or INT4 rate anywhere in the generation.

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.
Dense peak divided by accelerator TDP. Board power only: excludes host CPUs, networking, cooling and facility overhead. TDP for this part: 250 W.
