Its 2016. What did you expect?
Given that I have AppleCare on a 2012 QuadCore into 2018 (Jake, my refurb from last year that I posted about upgrading), I'd say that's a pretty good run of supporting a model, given that Intel has been on their Tick-Tock pace of pushing out new chips every year / as fast as they can.
That would be rad. I don't think 4 RAM slots would fit in it though and a dedicated GPU isn't needed since Thunderbolt 3 eGPUs are coming out.
If we get a Skylake Mac Mini, It'll be using DDR4 - SO-DIMMs hopefully. In that case there's a doubling of density supported, so 2 SO-DIMM slots plus the Intel Chipsets = 32GB RAM support - and *possibly* 64GB support on 2 DIMMs
A new Mac Mini model with quad core i7, dedicated GPU, and four RAM slots!
Hey, I can dream, can't I?
Dreaming is good. What we need is someone in product planning at Apple to realize they can put some excitement back into the Mac Mini range with a top-end CPU offering.
The Unibody Mac Minis have historically topped out at supporting about 45 watts TDB of power dissipation. Intel now has Quad Core chips with extra GPU slices and EDRAM in that power envelope up to the 3.0 Ghz range. And they have announced their own "Skull Canyon" NUC, with a Quad Core + 580 Graphics & 128MB EDRAM using the Xeon E3-1575m v5 chip or a lower binned variant of that. The existence of the Skull Canyon NUC will probably do more to make Apple consider such a quad-core product than all of our online posting combined.
I guess we can dream. A Mac Mini with 45w Quad Core + Iris Pro 580 CPU, 2 SO-DIMMs sockets, and leaving the connectors for 2x 2.5" drives along with a M.2 slot would absolutely be a 'Halo Model' garnering a lot of attention and making it the power system to beat in the NUC / tiny PC space.
As Aerosmith said.... Dream On.. Dream On..
