A new llama.cpp PR claims about a 15% boost in prompt processing on ROCm and fixes a bug that made Q2K up to 28× faster.
- The change targets HIP/RDNA4 MULMAT optimizations in ggml-org/llama.cpp.
- The author says prompt processing on AMD/ROCm improves by around 15%.
- It also fixes a bug affecting Q2K, which could make some extreme quantization setups much more viable on AMD GPUs.
