It could be 'M' for mediocre, knowingn Apple and gpus.
It's gonig to be a 'mobile' and SoC future. And these mammals will blow away the dinosaurs of yesteryear. So, ultimately, it's academic. It's about screen sizes and tuning hardware accordingly. Semantics, ultimately.
Simply. Does what's coming perform better. Or is it an excuse to palm customers off with inferior kit guised under superior marketing.
Can we see an Apple SoC gpu beheading the 5700XT? I can.
As for the 6600M.
It may be mobile. It may be more expensive. It may perform less well than the desktop part.
We don't want cut down, under performing parts priced higher than desktop parts that perform better and cheaper.
It may be better performing than the gpus in the current iMac (not that difficult...)
Change my mind? (I was raised by lots of women. So it's certainly possible...heh, heh, heh...)
I actually have a 'laptop' gpu (it's dead Jim...) in my 'dead' iMac. The 'actually not bad' 680MX which was, in fairness, a top ten gpu part of that year. And it's a laptop gpu.
That didn't stop me wanting better 'desktop' gpus in the iMac, though. As it is an area Apple have always skimped on along with RAM. (At least offer consumer towers that can take 'proper' gpus..., Apple...at g'damn reasonable prices.)
I recall that iMac owners rioted one year...and Phil Schiller had to come out and offer a new GPU BTO option (an Nvidia one...ironically...) Which shows. If Apple can get away with offering less GPU, they'll do so. And that they CAN be pressured into offering better.
Out with old iMac tech'.
In with new iMac tech'.
1st rate prices with 1st rate components.
Hope that's crystal clear.
