Qwen3.8 27B on the AMD Radeon 890M
Qwen3.8 27B runs at about 2.7 tokens/s on the AMD Radeon 890M (measured, UD-Q4_K_XL, Vulkan, single-stream llama-server decode).
Best measured: 2.7 tokens/s generation (UD-Q4_K_XL, Vulkan). The source gives no prompt-processing figure.
For comparison, our size-scaling estimate for this combination is 6.0 tok/s.

| Quant | Backend | Generate tok/s | Prompt tok/s | Test | Build / by / notes | Source |
|---|---|---|---|---|---|---|
| UD-Q4_K_XL | Vulkan | 2.7 | – | decode, llama-server, MTP off | Baseline (spec-off) column of a paired MTP A/B: llama-server single stream (--parallel 1), probe.py median, not llama-bench. | qwen38-mtp community table (GitHub) |
tg128 = generating 128 tokens; pp512 = reading a 512-token prompt (llama-bench). LocalScore averages several prompt and output lengths, so its numbers run lower than tg128. "decode, llama-server" = single-stream generation speed measured against a running llama-server (no speculative decoding).
