R9700 llama.cpp ROCm: Qwen3.5-27B decode at 2.9K prompt (u/neuromacmd)

r/LocalLLaMA post 1s4bggo, EDIT 3. llama.cpp, the same unsloth GGUF files copied onto every machine, batch size 1, one request. Prompt processing column is labelled 'PP tok/s (2.9K)' so the prefill figure is for a ~2.9K-token prompt; generation is the decode rate of that single request, not an aggregate across concurrent requests. Fedora 43 host for the AMD cards (Ryzen 9 9900X, 192 GB DDR5-5600). Build for the AMD rows of this edit is the post's original llama.cpp (b8500 is named only for the Mac Metal run). Backend: ROCm.

EDIT 3 of the post, ROCm backend, single GPU. The post's original table and this corrected same-GGUF table agree on these AMD cells. Per-request, batch 1.
