Maybe the "A" is for Apple, a batch with more strict quality control 🙂
Another question for OP: Is it possible to run OpenCL on both GPU:s simultaneously?
Also, thanks for your time doing this review!

Yepp, that is true for the 4750HQ and the 4850HQ. On the 4960HQ the Iris Pro has its maximum clock speed a 1,3Ghz.
If you have the money and a reason why you might need a dGPU now or in the future, I think you should get the dGPU. If you are concerned about heat/noise/power - just force the computer onto iGPU using gfxCardStatus.

is it a new samsung?
i ran mien on my 2012 and it just shows LSN154YL01001 but not A01?

My 15" 2.3GHz Retina MacBook Pro just arrived, and it's pretty much what I expected! Haven't had a chance to test the battery life yet, but here are a few bits and pieces:
The UK keyboard now has a # symbol as well as a £ symbol on the "3" key, this seems to be new as it wasn't present on my 2012 rMBP or on my Apple Bluetooth Keyboard
The display is a Samsung LSN154YL01-A01
When I logged into iCloud I got the usual email warning me that my account had been used to log into a new computer, except it said it was a 13" rMBP as opposed to a 15" - odd.
The colour temperature is a little different than it was on my old rMBP, although even among screens from the same manufacturer in the last generation there was a high level of variability. I'll report back when I've done some more testing.

So I went and got one a couple hours ago. 750M one.
Bought a Double DVI adapter to go with it, and decided to test to hook up the 24", 30" and see what happens. So:
30" via TB, 24" via HDMI. 1920x1200 + 1920x1200 + 2560x1600 =

I'd be interested to hear any reports on how hot the 750M gets, and in which circumstances it takes over from the Iris Pro. I know gfxCardStatus is an option for disabling the discrete GPU, but it can be buggy, and development seems to have slowed. It isn't at all clear to me yet whether the 750M is desirable in the new MacBook Pro Retina, especially in regards to heat and battery life.
But not integrated Intel Graphics with only 128MB of VRAM yet, as far as I've heard.
I'm starting to drift back towards getting a 13" rMBP. Anybody out there with a new machine want to post some comparison benchmarks? Please?
It seems from what people are posting here that the 750m is clocked at 925 but it should be clocked at 967 at least, because that's the manufacturer specification for this GPU. What's going on! Is apple screwing us?
Let's hope so. I'm no expert on these things. But I know I just paid a lot of money (3000 dollars here in the UK) for the top end 15". I hope I'm not getting a nerfed 750m. I'm going to be pissed off!
I went with the 16gb because I do the same stuff, but I occasionally use VMWARE/Parallells for development testing, so the extra memory helps there. Also the extra memory photoshop will appreciate, not to mention it will appreciate the graphics accelerator, since I believe it taps into that.

Buggy? Slowed development? It works just fine and as intended, which is why there's nothing left to develop. It does what it's supposed to do.
Money aside, the 750M is absolutely desirable. I continue to be perplexed by people who are on the fence about this.
----------
While true, I don't understand the point of this comparison. In almost no cases will any rMBP user be using the HD4000 for OpenGL stuff, regardless of whether they buy a current or previous model. That stuff would almost always been done with the GPU, which will generally beat Iris Pro (and sometimes substantially).
----------
This is inconsistent with what you said later in your post. If you're a gamer, you'd prefer either the Haswell high-end or one of the Ivy Bridge models. You really don't want the Iris Pro.
----------
Absolutely agree with this 100%.

Just picked up my 2.3/16/512/750 from the Altamonte Apple Store here in Orlando. Also have the Samsung panel (looks great to me). Absolutely no lag/tearing while slinging window around even with a scaled display resolution to get a larger desktop.
Upgraded from a late 2011 15" cMBP - faster, awesome display (of course), lighter, USB3, 2 TB ports - happy camper here.
A big advantage to me that I have not seen mentioned anywhere is that the display does not have the slight contrast variation with vertical viewing angle (i.e. the angle of the screen). This is huge as my primary power usage of the machine is for photography (LR) and it was always a little tricky to make sure I had the screen/lid on my old 15" at the correct angle to match what I saw on my Cinema Display on the desk. And, yes, both screens are calibrated with ColorEyes Display Pro & X-Rite Display Pro.
Expensive, but a fantastic laptop.

Thanks, but it hasn't always worked "just fine" for me, and Cody (the developer of gfxCardStatus) seems busy with other things these days.
If you don't agree that issues and merge requests are being handled more slowly on the Github repo of late, then we'll have to agree to disagree.
However, Cody did post on Twitter within the last few hours, specifically recommending non-NVIDIA MacBook Pros to a few different people...
Hearing some that are happy upgrading from the 2011 MBP makes me even more excited to upgrade from the base mid-2009 MBP 13" 😉
For me I'm on the fence. This is a work machine - I develop software for a medical device company using the MS Kinect so half the time I'm in a Win8 VM working on the software for that (some which may include Unity 3d dev), the other half I'm in OSX developing a Rails admin app and data backbone.
I'm not sure exactly where the video card will fit in for my workflow - esp. if the difference is only about 30% or so best case, there probably will never be a use for it outside of driving a 4k display if I do that down the road. I tend to work away from my desk alot so battery life is important. Mainly just bought the maxxed out machine as the horsepower will be beneficial and it's on the company's dime. A game will probably never be installed on it.

There's 8 open tickets. 120 closed. None of those tickets appear to be showstoppers; most are either feature requests or issues with aesthetic/cosmetic issues. The only one that seems mildly important is the 2010 MBP fix merge request.
So, handled more slowly? Yeah, I guess. But as a guy who used to run a software team, I completely understand where he's coming from, and I probably wouldn't be wasting my time either.
I checked that Twitter post, and he's just talking about heat and battery. Nothing new there. That's a statement of fact, not an endorsement of the iGPU option unless a user is particularly concerned about those issues, and it's certainly not him saying that there's an issue with gfxCardStatus that he knows about but doesn't feel like addressing.

Well, I'll note that I do see quite a big performance difference on my old 15" rMBP when using its iGPU versus the dGPU under my Win7 Parallels VM. That said, obviously Iris Pro should close a lot of that gap, so it's anyone's guess how those comparisons will shake out. I'll be curious to read what you and others think on that issue.
The only argument I can see against getting one with a dGPU, money aside, is for people who use Boot Camp. Assuming Apple hasn't changed anything, being locked into using the dGPU sucks for battery life.
