Depends on what you do. Let's say Apple makes an M3 "Extreme" and sets max memory to 512GB of RAM.
That's 512GB of high bandwidth RAM that you'd have to piece together 7 Nvidia H100 80GB cards to match. Each H100 80GB card costs $30,000+. Seven of them would cost $210k alone.
Now of course 7 H100s would have more compute power, but if what you need is a lot of high bandwidth RAM such as a large LLM or highly detailed scene rendering, then maybe an M3 "Extreme" would have the best value out there, by far.
