I get around 25-30% of CPU load and if I try to hibernate the system it. The ONLY thing that I can't by any means get to work is to not have the CPU idle crazy load. Also, looking at msi afterburner my egpu was at 100%. I get to the point where I basically have the egpu working and I tried running Tomb Raider's benchmark (what I had at hand) and it was going smoothly (which wouldn't be like that with the iris or dgpu). Then disabled the dgpu on the device manager, used the switch-gpu bat file as admin to get the igpu as main, so far so good. Since I was using a Win 7 on Bootcamp/BIOS I decided to start from scratch: got a Win 10 EFI installed, got reFind so I could activate the visibility of the Iris igpu, and although it seems to be much more buggy, got to run the system with the egpu. I have a MBPr Late 2013 (GT750M dgpu) with an Akitio Thunder Box, with a dell power supply (which I always thought it might not be enough because I had to limit the power with Afterburner to 80% so it wouldn't shut down when playing a few hours) and an Nvidia GTX970 (KFA 4GB).

Recently I read that disabling the dgpu was an option so I quickly got 'up to date' reading the new stuff, but I might have missed something. Keeping that in mind: I just wanted to know if anyone found a fix for the cpu idle bug without hibernating.įirst of all, I made my setup in 2015 and I just used an external monitor since at the time making it work with optimus having a dgpu was unknown. I´m trying to find different benchmarks results for different Mini´s with different configurations and see the differences. I tried to find real cases but all of them are with really different Mac Minis configs, RAM and eGPU´s so I´m still little confused. With these data I would choose 2012 model, but I´m not sure if Thunderbolt 2 would be a great improvement to my eGPU. PROS : RAM upgrading, Better CPU´s (4% slower single core, 46% faster in multicore)ĬON: iGPU Intel 4000 90% Slower than Iris 5100, Thunderbolt 1ĬONS: RAM Soldered, slower CPU´s in Multi Core Hi again, it looks like in terms of CPU the 2014 i5 CPU´s are a little bit faster than 2012 in single core but slower on multicore proceses.Ģ014 models starting in 2,6 Ghz goes with Intel Iris Graphic 5100 with is twice faster than Intel 400 on 2012 models.

What is the mac mini 2012 graphics card
