Maybe the m2 won’t be about power but about even more energy efficiency ?
I think a lot of people will be disappointed by the new mini when it arrives
It's more than likely to be based on the A15 CPU which has extra GPU cores when you consider variants used in the iPhone Pro and iPad mini 6 models (5 vs 4). This makes sense if you then consider that M1 has 8 (or 7 in the binned version) Graphics cores.
Therefore the M2 CPU should expect a slight increase in all the usual benchmarks but the headline change would be extra GPU grunt with 10 GPU cores (or 9 if they are binning them).
This Tweet from Steve Troughton-Smith suggests 6% increase in CPU per core plus significant increase in GPU due to extra cores (although I think he's got confused with amount of performance cores there):
If as suggested the mere existence of the Mac Studio suggests that Apple decided to launch in effect the Mac mini Pro it would make sense for the M1 Pro to not arrive in that model in the short term so that people who want 32Gb RAM in a headless Mac satisfy pent up demand by buying the base model Studio.
With unit shortages due to pandemic likely I think Apple may decide to chase a higher average selling price for Macs rather than try to go for volume sales.
In the medium term, if Apple were to launch an M1 Pro variant with 16Gb RAM base and 32Gb BTO option those buyers may gravitate towards that model instead, but profit levels might be hit by lockdowns etc slowing shipments.
Apple might well be tempted to let the current M1 Mini (along with the MacBook Air) stay on the M1 chipset - they could redesign both to give them sales boosts (and in the case of the Mini perhaps fix the wireless/bluetooth issues).
In both cases the Eurasian database lists one more desktop model (the Mac Studio was the other one) and a laptop which some observers have debated whether it's a refreshed MBA, a new MBP, or a MacBook to replace them both.
I doubt Apple will be needing to fill that database in for the near future with what's going on in Ukraine.
Back to the Mini though, if you look at the shipping delays in the Mac Studio you can see that Apple have problems keeping up with demand which might be lockdown related. There are currently no such problems for the M1 Mini but you do wonder if Apple open up a manufacturing line for the M2 to to use in new products whether they might become susceptible to supply chain disruption early on.
Perhaps Apple had plans to launch product earlier than they have but as it stands if they were to launch an M1 Pro Mini now it might result in cancelled orders for the Studio as people switch down to a potentially less profitable machine.
Having said that, though, has anyone had any thoughts on what the connectivity of an M1 Pro Mini would look like?
We see the following for M1:
Mac Mini
2 USB4 (Thunderbolt 3) ports, 2 USB-A (5Gb/s), HDMI 2.0, Headphone, Ethernet (10Gb/s option)
iMac 24
2/4 USB-C ports (configured as 2 or 4 USB4 ports (Thunderbolt 3), if 4 ports then 2 are 10Gb/s USB 3.1 Gen 2), Headphone, Ethernet (on the Magsafe brick, no 10Gb/s option)
MBA 13
2 USB4 (Thunderbolt 3) ports, Headphone
MBP 13
2 USB4 (Thunderbolt 3) ports, Headphone
When we go to the 14 and 16" MBPs we have (as well as the Magsafe charger):
3 Thunderbolt 4, HDMI 2.0, SD Card slot, Headphone
Some of this could be down to space issues on a laptop, clearly an M1 Max (see below) could drive more ports but the MacBook Pro simply doesn't have the room for them.
Obviously we know from the Mac Studio that the M1 Max runs 4 Thunderbolt 4 ports, 2 additional 10Gb/s USB 3.1 Gen 2), SD card slot, 10 Gig Ethernet, 2 USB-A (5Gb/s), HDMI 2.0, Headphone socket
So would we expect an M1 Pro Mac mini to copy the port selection from the 14" MacBook Pro?
3 Thunderbolt 4, HDMI 2.0, SD Card slot, Headphone
The current Mini doesn't carry the SD Card slot so we might expect that to be replaced by a pair of USB-A (5Gb/s) ports and there might be enough bandwidth left to put Ethernet (with 10 Gig option) on.
The question then is for the completists who would want the 4 Thunderbolt ports that the high end Intel model sported (even though they were run by only 2 Thunderbolt controllers whereas the ARM Macs appear to have one controller per port).
Apple certainly could leave things there because they wouldn't want people too at home on an M1 Pro Mini in case they'd like to be upsold to a Mac Studio.
