I have a RTX PRO 6000 96GB when the pricing was way better than now i also have a RTX 5090 too.

What I noticed is that (1) the great local models are optimized run inference (diffusion & LLMs) well on 32GB VRAM <= GPU's because that that's what the target has ...

(2) The quality of local models (esp. in diffusion) is increasing faster than the need for more VRAM - additional reason for the value of these FAST GPUs to increase!

(3) RTX PRO 6000 96GB is really great for fine tunes (ai-toolkit) :) but doesn't outperform my RTX 5090 with inference by anything significant on the good local models.

I have never run an AI job on a Mac, i also have doubts about performance and compatibilities - since the reviews almost never compare directly.
