If you have enough 4090s, you don't need to page in and out of disk: everything stays in VRAM and is fast. But it's true that if you just want it to work, and you don't need the fastest perf, Apple is cheaper!
- Y-bar 2y agoHow _exactly_ do I keep 50+ Gigabytes of data in the 4090's VRAM without paging back and forth to disk?
- angoragoats 2y agoAs the person you’re replying to said, by having multiple 4090s. 3090s work pretty well also, and are less than half the cost of 4090s.
- Y-bar 2y agoHow is that relevant when the discussion from the start was about comparing a two year old Mac with a two year old GPU as a cost-benefit discussion. In any case how are you going to fit 50+GB in two (theoretically 24+24 GB) Nvidia cards without swapping to disk when the Mac in question has 64GB (also theoretically) available?
- angoragoats 2y agoYou seem confused. Please feel free to read my post near the top of this very chain of comments, where I specifically compare a Mac Studio to a machine with 6 to 8 Nvidia GPUs. That was the discussion “from the start.” > In any case how are you going to fit 50+GB in two (theoretically 24+24 GB) Nvidia cards No one was talking about only two cards.
- Y-bar 2y ago> Mac Studio to a machine with 6 to 8 Nvidia GPUs. That post read like a joke comparison and still does. Can you elaborate how it is relevant?
- angoragoats 2y agoWhat seems like a joke about it? And relevant to what, exactly? The parent of my initial comment in this thread said: "For inference, Apple chips are great due to a high memory bandwidth... It's a cost effective option if you need a lot of memory plus a high bandwidth." My post was attempting to explain at a high level how 1) Apple SoCs do not really have high memory bandwidth compared to a cluster of GPUs, and 2) you can actually build that cluster of GPUs for the same cost or cheaper than a loaded Mac Studio, and it will drastically outperform the Mac. If you want specifics on how to build such a GPU cluster, you can search for "ROMED8-2T 3090" for some examples. I hope this helps.
