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?
The Motherboard and RAM alone cost another $2300… The CPU, Ram, and Motherboard looks like $4500 rounded down… How does this make sense versus three 3090s?
