While I agree it's expensive it's not quite apples to apples. GPU memory is very very expensive. A100 80GB costs $10k msrp (> $15k on ebay). An RTX 4090 only has 24gb of vram at $1600. Even if you do dual 3090's + nvlink for $1600 you only get up to 48GB, no where near the up to 192GB of vram you can access on apple silicon. The upgrade from 64GB to 192GB of ram is $1600. That's still expensive of course, but 128GB of 800GB/s memory that your GPU has access to for $1600 is actually not bad value. It's not like just sticking an extra 128gb of ram into your computer. DDR5-6400 dual channel will give up up to 102 GB/s, which is no where near M2 Ultra or GDDR6X.
