Optimizing gpt-oss-120b speed on consumer hardware

Authorship note Parts of this post were drafted/refined with the help of gpt-oss-120b itself. How meta! TL;DR # Hardware : i5-12600K (6P + 4E), RTX 4070 (12 GB), 64 GB DDR5 RAM, Linux (CachyOS, CUDA 13.0). Result : 11 tokens/s -> 25 tokens/s generation, 420+ tokens/s prompt processing for 32k context. Biggest win : Enabling DDR5 XMP in BIOS. My RAM was running at 2000 MT/s instead of 6000 MT/s for…
