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?
At full precision as in FP16, you are not going to be able to fit ot in a 4090. So if that’s your goal, between the choices you are giving, there is only 1 choice. But it won’t be speedy.
