Not my settings! All credits to "Stainless-Bacon". I did however replicate the setup just now and I think it's worthy of spreading. The trick is in a targeted offloading of only a specific kind of layers to CPU making it possible to run a higher quant that otherwise would be too slow to be usable. Remember to compile llama.cpp with GGML_CUDA_FA_ALL_QUANTS=ON Original settings below. Since I'm using the iGPU for the system I'm slightly tweaking them to use even more VRAM. On my 5060Ti I'm getting prefill 500-600tps (ub at 2048) and tg at ~10tps. export GGML_CUDA_DISABLE_GRAPHS=1 llama-server
