So the only reason the mac is faster is because the RAM is accessible by its GPU, right? Not because the RAM is faster than regular RAM, because AFAIK it isn't far off from workstation RAM speeds.

The RAM is faster. 8 DDR5 64GB sticks at 8800 MT/s would in theory give you a maximum of 563.2 GB/s. Whereas the M3 Ultra is 819 GB/s.

Can anyone even get 8 sticks to run together at 8800?

I'd say "No". IIRC the current number is somewhere 5-6K
