Summary
User reports Qwen3.6-35B-A3B at ~110 t/s on an AMD RX 7800 XT 16GB with MTP and turbo4 KV cache at 32K context.
Setup is a NJannasch llama.cpp mtp-turboquant fork on ROCm 6.4.0 (gfx1101) with UD-IQ3_XXS GGUF, turbo4 KV cache, --spec-type draft-mtp, and --reasoning-budget 512.
MTP acceptance was 86% at 32K context; turbo4 KV saved ~470 MB vs f16 at 32K. The user warns that a silent CPU fallback can drop generation to 5-10 t/s and that gfx1032 cards crash with this fork.
