What's crazy is that the M4 Pro is in the Mac mini, something so tiny can handle that chip. The Mac Studio with the M4 Max will be awesome but the Mini is remarkable.
I am still astounded the huge change moving from an Intel Mac to an Apple Silicon Mac (M1) has had in terms of battery performance and heat. I don't think i've heard the fans a single time I've had this machine and it's been several years. Nor have I had any desire to upgrade.
I never thought I'd see a processor that was 50% faster single-core and 80% faster multi-core and just shrug. My M1 Pro still feels so magically fast.
I'm really happy that Apple keeps pushing things and I'll be grateful when I do decide to upgrade, but my M1 Pro has just been such a magical machine. Every other laptop I've ever bought (Mac or PC) has run its fan regularly. I did finally get fan noise on my M1 Pro when pegging the CPU at 800% for a while (doing batch conversion of tons of PDFs to images) - and to be fair, it was sitting on a blanket which was insulating it. Still, it didn't get hot, unlike every other laptop I've ever owned did even under normal usage.
It's just been such a joyful machine.
I do look forward to an OLED MacBook Pro and I know how great a future Apple Silicon processor will be.
