I still have a Mac Mini on my desk in my home office, regardless of the laptops. If I were into crunching 192 gigabytes of numbers at a time, I’d get myself a Mac Studio.
At least until someone makes an MI300A workstation.
Sure, but then if you take your code to production to monetize it as a business you won't be deploying on a datacenter of Mac Minis.
What you alone do at home, is irelevant for the ML market as a whole, along with your Mac Mini, as you alone won't move the market, and the companies serious about ML are all-in on Nvidia and CUDA compatible code for mass deployment.
I can also get to run some NNs on some microcontroler, but my hoppy project won't move the market, and that's what I was talking about, the greater market, not your hobby project.
