A user moved from UD-Q3_K_XL at 140k context to UD-IQ3_XXS and cleared 200k on a 16GB eGPU over Thunderbolt 4, with KV cache at q5_1 and llama.cpp built with DGGML_CUDA_FA_ALL_QUANTS=ON (r/LocalLLaMA). Prompt processing fell from 700-800 tok/s to 400. A commenter on an RTX 5080 with KV at Q4_0 and vision forced to CPU via --no-mmproj-offload reported 1750 PP/s and 85 TG/s at 132k context, which is the better-balanced configuration of the two.
