(I just posted this on the Gearspace forum. I think it fits in this thread, so it's mostly a copy/paste.)
I've just ordered a Mac Mini M2 Pro, 32/512.
My plan since the M1s came out was always to wait until around the M3 to make my next significant investment in a desktop computer. I changed my mind now, since it looks like a M3 Mini (my preferred form factor) coming next year, will be pretty costly without having too much improved performance overall.
I've had these Minis: 2018 intel 32GB, M1 16GB, and the last year an M2 16GB. All good macs, but the big jump was of course intel-to-M1. The M1-to-M2 was hardly noticeable.
The M2 has been great. The 16GB, a little tight, since my main power/ram drainers are Avid Pro Tools for music/mixing, and especially my big Lightroom catalogue. So I looked at swapping it for an identical mac with 24GB, the max it can have. But I'll be doing the "leap" now instead of waiting for the M3 Minis. Here's why:
My new M2 Pro vs my current M2:
32GB RAM instead of 16 or 24.
Double memory bandwidth.
6 performance cores instead of 4.
16 GPU cores instead of 10.
(Means it handles 3 displays instead of 2, and has faster refresh rates.)
4 Thunderbolt ports instead of 2.
512GB drive instead of 256GB, and double bandwidth/speed.
HDMI 2.1 instead of 2.0.
After I sell my M2 mini, the transition will cost me about $1500. But I think it's a very solid configuration, and should hold well in value for a number of years.
(The actual cost of the M2 pro mini with 32GB ram from the Apple store here in Norway is about $2400, but you must take into account the bad state of our currency nowadays, our 25% VAT, and our generally very high scandinavian price levels.)
I'm confident that I've made a good choice, and having used the M2 for almost a year, I'm sure I know what I'm getting. It's also very nice that I can simply pull all the plugs from my M2 mini, and insert them into the M2 Pro, and everything will work, like it did with the previous mac mini transitions I've made.
