I think you know what I mean- a discrete GPU as opposed to on-CPU GPU.
Discrete GPUs often have hundreds or thousands of compute cores...
I'm a fan of the PowerVR stuff they licensed. I thought it was cool when I first came across it. I had a PowerVR video card for a bit- I was disappointed that it didn't catch on bigger. I remember learning that it was in a LOT of mobile chipsets though, so I guess they got their wins there and again with Apple licensing the tech.
And I'm not a Windows guy... I'm just not an Apple fanatic that takes every opportunity to crap on stuff that other people use that isn't Apple. I was real close to using an iPhone recently but seeing how Apple suppressed communication for protesters in China recently killed it for me. I just couldn't do it. They make some cool stuff, and some stuff I'd never use in a million years.
