It appears that
Apple may be using the i7 4950HQ (with Iris Pro 5200 graphics) in a future Macbook Pro. This could be a Retina or non retina version although the story suggests the tested Macbook pro doesn't have built in discrete graphics and the
cost of the CPU itself (Anandtech suggest $657 for the i7-4950HQ which may be a BTO top model, with the 2.3GHz i7-4850HQ weighing in at a more reasonable $468) hint strongly towards leaving a discrete GPU out.
If we follow the Macbook Air reasoning, it suggests Apple could be leaning towards longer battery life, thinner case, and less heat throughout their range.
We already know that Apple pushed strongly for Intel to improve their
integrated GPU offering in Ivy Bridge but they were knocked back.
While all this should really belong in a Macbook Pro forum, I think there's now a case for those HQ cpus being used in a revamped Mac Mini which would use PCIe flash and perhaps retain a SATA3 drive bay and connector to enable use of a Fusion drive.
Is there any scope for Apple now to include the 'missing' GPU into a revamped Thunderbolt 2 Display to bring some graphics performance for all Thunderbolt equipped Macs on the big display? After all, there's plenty of room for a GPU and a cooling solution inside something that's not too different from an iMac, plus it keeps a very hot GPU away from the main CPU unit...
I know that the Thunderbolt connection could be seriously constricted if it's providing ethernet, USB3, Firewire 800, and perhaps an NVidia GT750m as well though...
