AMD Radeon RX 6700 XT 12GB
Overview
The Radeon RX 6700 XT is the 40 compute unit Navi 22 part and the volume RDNA 2 card of 2021, with 12 GB of GDDR6 across a 192-bit bus and 96 MB of Infinity Cache. Twelve gigabytes at this tier is why it still appears in local-inference shopping lists years later, since it clears models that will not fit an 8 GB card. On throughput there is no subtlety to unpack: RDNA 2 has no matrix cores, AMD publishes 13.21 TFLOPS FP32 and a packed 26.43 TFLOPS FP16 at exactly twice that, and nothing else. No BF16, no FP8, no INT8 or INT4 rate exists for 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.
Per watt divides the dense figure by the 230 W board power. Where only a sparse figure exists, the cell says so.
