I plan to infer 33B models at full precision, 70B is second priority but a nice touch. Would I be better off getting an AMD EPYC server cpu like this or a RTX 4090? With the EPYC, i am able to get 384GB DDR4 RAM for ~400USD on ebay, the 4090 only has 24GB. Moreover, both the 4090 and EPYC setup + ram cost about the same. which would be a better buy?
My AMD 7950X3D ( 16 core 32 threads), 64GB DDR5, Single RTX 4090 on 13B Xwin GGUF q8 can run at 45T/S. With exllamav2, 2x 4090 can run 70B q4 at 15T/s. Motherboard is Asus Pro Art AM5. In Local LLama, I think you can run similar speed with RTX 3090s. But in SD, 4090 is 70% better though.
