Just waiting on the M2 Pro Mac mini...
That would be a M2 Pro Mac Studio - no point having a M? Pro without the extra ports it supports over the regular M?, and you'd probably need the beefier power supply and cooler from the Studio enclosure (yes, the Mini enclosure used to run Intel i7 space heaters but not near-silently: Apple seem to be going for cooling overkill now).
Would kill most Mac Studio so not happening.
There's a spot in the $1100-$1500 price range - currently occupied by the Intel Minis.
If you look at the MBPs, the difference between 16GB M1 Pro and 32GB, 24 GPU M1 Max is $600-$900 so - working back from the $2000 starting price of a studio, you'd get a M1 Pro Studio for $1100 to $1400...
If the M1 Pro MBP doesn't kill the M1 Max MBP, why would a M1 Pro Mini/Studio kill the M1 Max Mini/Studio? Well, I guess sales volumes of desktops are much lower - there are more laptop sales to go around before numbers get too low to be viable. Also, going for a M? Pro over a M? Max
in a laptop improves battery life and reduces noise - on a desktop that's not an issue - you're just choosing a knobbled GPU to save a few hundred bucks, especially if you wanted 32GB RAM anyway (the mandatory 16-32 RAM upgrade costs more than the Pro to Max CPU upgrade).
It's a slight surprise that we didn't see a M1 Pro Studio from the start - my suspicion, though, is that there just isn't enough clear advantage between the regular M2 (which will presumably roll out to the Mini shortly) and the cheapest, binned M1 Pro.
Hmm. I suspect that the 24GB option is a stop-gap for the regular M2 because some people wanted more than 16GB without going to a Studio/MBP. I doubt we'll see a 24GB option on SoCs that can already do 32GB.
The M2 got LPDDR5 and a wider RAM bus than the M1, enabling the 24GB option.
The M1 Pro/Max/Ultra already got the RAM controller upgrades, so I don't see any physical reason why Apple couldn't have offered 24 (Pro), 48 (Max), 96GB (Ultra) options in the MacBook Pro or Studio range - apart from the logistics cost of producing that many different SoC versions.
