153 tok/s on 1x AMD Radeon R9700 running Qwen3.8 27b NVFP4, 470 tok/s @ 8 conc requests, Prefill @ 3,619 tok/s

People kept commenting and asking about single AMD 1xR9700 cards in the comments and discord. Well, I finally had time to do some optimizations for 1xR9700 owners and performance has doubled across the board. You can see the results in BetterBench above if you like visuals or below if you're more into text.

These results were measured running Unsloth's Qwen3.8 27b NVFP4.
