Title says it all, I run dual 3090s (check out my post here for my setup) at int8A16 and have been wondering if I'm missing out much with QFN. There's posts on here ad-nauseam about low bpw strata solutions on heterogeneous systems, however those don't interest me - I want high precision. I'm considering selling my setup and getting a DGX Spark, but that can run QFN at nvfp4. My use case isn't coding but generic agentic use case - use hermes as a personal assistant and with openwebui. If anyone's able to run both and do a comparison, please let me know!   submitted by   /u/GoblinEngineer [link]   [comments]
