the 4600 might switch more often due to being slower
however
normal usage should never trigger the dgpu, only gaming / video editing should, though some people complained previously about photoshop triggering the dgpu which is not ideal
it is true that the 5200 is faster at openCL than the dgpu, - so we might see a 5200 + dgpu (but unlikely) as a 4600 is a downgrade - or apple might let the customer purchase the machine to match their needs
reguarding gaming, the iris pro has different bottle necks than a dgpu so in SOME cases it can out perform e.g:

Yes the same forum but from different poster.
I checked the Intel website, Iris Pro 5200 equals to Iris 5100 plus 128M eDRAM, which is not dedicated to the graphic unit. The 128 eDRAM is actually a L4 cache that benefits both CPU and GPU, so it is not entirely unreasonable.

yeah, but the edram makes a massive difference:
RAM: 128-bit DDR3 @ 1600MHz = 25.6GB/s
eDRAM: @ 1600MHz = 50GB/s bi-directional bandwidth (100GB/s aggregate)
5100 only has ram to use
5200 has ram and edram to use
so you can see how the 5200 smashes the 5100

Iris Pro CPU's TDP are too high for the 13" chassis. That's why Iris (5100) is the only possibility for the 13". Iris Pro only in 15"
The current OS X GPU switching requires the software developer to implement this properly. Per default, if an application requests an OpenGL context, the machine switches to the dGPU. OS X includes some very powerful APIs which allow the developer to utilize multiple GPUs at the same time (no matter which one is actually active) - a sort of do-it-yourself SLI; and it is also quite easy to tell the OS that the application is satisfied with the iGPU for its OpenGL needs. Unfortunately, only few applications actually implement this. VLC is one notable popular app which does not and thus really drains your battery when open.
2.6 i7-4960HQ/16/512/Iris Pro 5200 + Nvidia GT750M with 2GB vRAM
-or-
2.3 i7-4850HQ/16/1TB/Iris Pro 5200 + Nvidia GT750M with 2GB vRAM
Hopefully the two above will stay in the ~2700 range. If its much cheaper Ill go all out. My understanding is...its
expect to pay prices (Now if only i came in brushed black....)

expect to pay prices (Now if only i came in brushed black....)i was really expecting for a visual modification in the macbook pro. i guess is not this time. A black one would be so sweet
if the igpu version is replacing the non-retina, then how come the third one in the list is a BTO? there is one missing in the list then.
this doesnt seem right.

I hope to god some of you won't have to sell a child into 7 years of servitude for this one.
What general delay?
Yikes!
Love, love the specs - best we could have honestly hoped for. Bit I'm scared the cheapest 15" with a dGPU is going to exceed $2200 because of the bigger SSD and more RAM. If that hits $2200, I'm buying it today.

I think this has something to do with phasing out cMBPs and lowering the price of the retina.
Best of both worlds. High OpenCL performance on the Iris + high OpenGL on the NVidia. Fits the same theme as the dual GPUs on the Mac Pro.
It's the biggest Apple forum in China and someone works for manufacturers like foxconn get info and post on the web. Ahead of previous announcements, there were leaked photos and specs of Mac/iPhone/iPad posted on that forum, including 2012 iMac.
Here are some of the history records:

The gpus on the mac pro are identical, they work in SLI, totally different concept to having an iGPU and dGPU
They don't work in SLI. One is meant to be used for OpenCL, the other for OpenGL.
I recently sold an MSI GS70 (their newer thin, MBP-style 17" laptop), and that thing got down right hot with the 765M. Not warm, hot; like hot enough to burn skin. They even put felt on the bottom of it near the heat vents to keep it from doing serious damage if you used it on your lap.
Thin form factors and those types of GPUs are just too hot, or exceedingly loud, to make them feasible.
Not really, the 750M will be undoubtedly overclocked and it will allow them to leave a little headroom for heat.
