The 45 W Ivy Bridge CPUs used in the high-end 2012 include the same integrated graphics as the 28 W Ivy Bridge CPUs used in the low-end 2012, while the Coffee Lake 45 W CPUs include worse integrated graphics compared to the 28 W Coffee Lake CPUs.They did in 2012. What changed?
Apple didn't even consider eGPU a possibility in 2012.
The difference will be noticed when doing anything GPU-intensive (assuming whoever bought the mini couldn't justify or afford the cost of an eGPU, which is more likely than not to be the case). Even just comparing the specs of the two models, a weaker iGPU could be enough to dissuade someone from buying the more-expensive one.Those who hunger for GPU performance aren’t going to have a problem paying for that performance. As long as the iGPU is able to handle 4K output @ 60Hz it will be fine for the majority of people. It doesn’t matter if the top speed of a car drops from 155mph to 145mph if most people aren’t breaking 100mph, and the few that will be exceeding 145mph are also not going to want to stop at 155mph but go well past 200mph.
I don't think a 4-core with dGPU will happen regardless. The mini will top out at either a 6-core 45 W with dGPU, or a 4-core 28 W with iGPU.I would much rather have a 6-core with a low tier iGPU, over a 4-core with a low tier dGPU.
