So maybe you've seen something like this:

Well here are some screenshots from a YT video I found interesting on the subject (video linked at the end). In a nutshell, AVX 512 is an instruction set architecture designed for 512 bit wide instructions. This rabbit hole will maybe help you understand why CPUs are so much slower than a GPU, or at least, if you already know the basics about computing architecture, this will show where the real bottleneck is located.

I'm really curious how well various AVX 512 architectures improve CPU performance. Obviously it was worth implementing a lot of these instructions into llama.cpp, so someone felt it was important. In my experience there is no replacement for running a large model. I use a Llama2 70B daily. I can't add more system memory beyond the 64GB I have. I need to look into the potential to use a swap partition for even larger models, but I haven't tried this yet. Looking at accessible hardware to use with AI, the lowest cost path to even larger models seems to be a second hand server/workstation with 256-512GB of system memory, as many cores as possible, and whatever the best implementation of AVX512 accessible for a good price then add a 24GBV consumer GPU to this. That could still be less than $3K and on paper it might run a 180B model, and still be cheaper than just a single enterprise 48GBV GPU. Maybe someone here has actual experience with this and how various chipsets handle the load in practice. It is just a curiosity I've been thinking about.
