The Mac Studio is the most exciting Mac for decades. A high-performance desktop that could match a high-end PC, at a similar cost, and without a built-in display.
It’s like if I took the latest Intel/AMD CPU, the latest Nvidia GPU, and built a custom PC. It would cost maybe $3-4k and offer a level of performance that we just didn’t have on the Mac. The Studio finally gave us an answer to that.
The Mac Pro was always a weird machine. It had enterprise and workstation-class components, and so it targeted a market where machines cost double (or more) than what I described above. Many people who need a high-performance Mac would still struggle to justify that kind of purchase.
I’d rather see the Mac Pro disappear and Apple focus on the Studio. If you need more computational power than a Studio can deliver, you’ll probably be better-served by a cluster or cloud service than by a single super-beefy desktop.
