Is there a good reason why AMD APUs just aren't used with massive amounts of (V)RAM just like the Mac M2 is? (lemmy.ca)

Is it just memory bandwidth? Or is it that AMD is not well supported by pytorch well enough for most products? Or some combination of those?

The memory bandwidth stinks compared to a discrete gpu. That’s the reason. It’s still possible.

The question is, though, would it be better than just a CPU with lots of RAM?

Yes, it seems so according to this person’s testing: https://youtu.be/HPO7fu7Vyw4
