Earlier quoted context omitted.
UMA is the secret. A 256GB Mac Pro can dedicate almost all of that to AI. Their GPUs are the weak spot. The Nvidia 4080 is 2.5x faster than the M2, and the A100 is 15 times faster.
The 4080 is _25x_ faster than the M2 on pure fp32 (which is what most GPUs are doing most of the time). Apple compared the M2 to the laptop 4080, using numbers heavily biased to them (running a 4080 at 10W does tend to make it not perform, yes). Not a single benchmark in the world has supported Apple's claim that the GPU in the M2 is that powerful. It's just yet another cute embedded GPU that does the job, but nothin…
But in any event, yes, that was my point. UMA is a huge advantage, the GPU itself is too weak to be serious.
But it’s a lot easier to drop a dramatically beefier GPU into a new design than it is to update the entire platform for UMA. Apple has a huge opportunity here… whether tbey pursue it or not remains to be seen.
