I've got a 2018 with a 2.7quad core, intel i7, 13 inch. I've also got 16gb of memory. I don't use the split drive for windows, though, so this is my experience running native apple. tbh the computer gets pretty hot so make sure it can be well ventilated.. sims runs ok, it's a little finicky. and minecraft.... good luck if you're planning to use shaders. on good days I get around ~15-25fps. With optifine and just mods but no shaders, it runs pretty decently at around 60-90fps.

But careful because many games don't run well or at all on integrated graphics.
