When I've tried running a ~14 gigabyte distillation of whatever model it is I was trying to run, it would come out super slow at I believe 50/50 GPU to CPU. It gets so slow it was just more bearable to run a 7 or 8 b model that would actually fit entirely in VRAM and run entirely on GPU. Also made the rest of computer usage more bearable.

To be fair I do only have a 6 core 6 thread CPU though. It shot up to 600% usage so even the DDR4 memory wasn't really bottlenecking it. I suspect a 9950X would fare a lot better.

I am using a 5950x, with 128gb of DDR4 3600 memory. The GPUs are a 3060 and 4090, totaling 36gb of VRAM. IMO, being bottlenecked by the CPU is definitely a thing, it just comes third after the VRAM and RAM considerations.

With a 35b+3a MoE at Q8 with KV8, I get...
