Currently I have a 4090x2 and I am looking to upgrade my machine. Due to well known reasons, the price of 4090 and 3090 is insanely high right now, and I see another option: magic modding a 3080 with 20g of vram.
My aim is to use qlora to fine tune a 34B model, and I see that the requirement for fine tuning a 34B model using a single card from qlora is 24g vram, and the price of 4090x2 is about equal to 3080 20g x8. so what would be a better choice for a multi-card?
4090x2 or 3080 20g x8?
You already have rtx 4090 x 2? Then why upgrade, i don’t get it. Tell me more about that magic modding, I can’t find anything related online.
