I believe Mr. MM was referring to the all too famous Schrödinger's cat.
To which I requested to see the cat.
I'll show myself out.

Once you get your Haswell MBP, just don't click "About this Mac."
Good point.
On a quasi-serious note, that's what I'm interested to see will happen if there's only an Iris Pro - what if everybody goes about their business, game, editing, and or 3D rendering, and it doesn't skip a beat?

As funny as that would be, one Anandtech review will fix that "ignorance."
Gotta love when people enjoy benchmarks, not their equipment.

You should know by now that's going to happen anyway - at least around here.what if everybody goes about their business, game, editing, and or 3D rendering, and it doesn't skip a beat?
After a few weeks a new breed of Apple apologists shall come forth extolling the virtues of The Mighty Iris... singing praises to The Sacred iGPU... relentlessly admonishing thine ignorance and irreverence for it.The hardware may change but some things in the universe are still constant.

True. I'd only be ok with iris pro if it just surprised everybody with its performance
People might be surprised if this score isn't because of some error.
If a HD 4600 can get close to 650M openGL bench scores, what can a real Iris Pro do under Mavericks.
That is 30% faster under OpenGL then in Windows, a similar advantage OpenGL games had when HD 3000 came about.
Iris Pro already rules in OpenCL just because it is more suited for it. There isn't much left for 650M to actually be faster in other than games. It won't come close to a 700M Nvidia dGPU in Windows gaming but for OSX with the right drivers Apple might come out and actually claim speed improvements in OSX. Rather than say we got better battery life and "hey, it isn't worse."
All we know is what Iris Pro can do in Windows but not how it does in OSX a platform where nvidia doesn't update its drivers every other month or cripples its OpenGL performance for the sake of higher margin Pro GPUs.
BTW one would also have to wonder why Mavericks would misidentify a 4600 for Iris Pro if they weren't using an Iris Pro in some upcoming product. What would be the point of implementing an Iris Pro OpenGL Engine.

There is a macbook air 13" with IRIS PRO? every macbook air has HD5000 only. So what a Nvdia 750M will score under Maveriks DP2 ?
No, there is no Air with Iris Pro. HD 5100 gets the label Iris and ONLY the HD 5200 gets the label Iris Pro. The HD 5000 as well as all the HD 4X00 GPUs don't get any Iris label at all because they are just not fast enough. The HD 5000 is so limited by its TDP that a HD 4600 beats it.
The point isn't what a 750M would do but that the next gen isn't worse then the previous gen. That is what so many hear seem to worry about. That suddenly the performance will be a lot worse and a newer model will apparently become useless because it is so much slower than the old.
But from the cinebench results on a benchmark page for the 650M in OSX compared to Windows scores it seems that Nvidia openGL is actually worse by quite a margin in this OpenGL benchmark (38 vs 44+fps). Under Windows a 750M should get a higher score then the Iris Pro in Mavericks (if the 30% difference is the same [close to 50fps for iris pro in mavericks]) but in OSX it would be a small advantage for Intel.
I wouldn't be surprised if in actual application performance (the whole video/picture/render stuff in OSX) the picture will look much better than many pessimists assume just because they hold Intel in such low regard.
I also read from Xbox developers that dealing with that SRAM is a pain but it can be done. The cache setup from Intel made it easy and if Apple puts some effort in there could be a lot of performance in that chip with the edram.

Check again..in that article the image says Macbook Air 13" with Iris Pro 1024 vRam and in the article says this is HD4600 so i think is a joke. But i do think the new dGPU or Iris Pro in combination with Maveriks roks and the difference between windows experience and MacOs is gone
It is a hackintosh. He actually runs a OSX Kernel on a normal Desktop rig with a 4670K Haswell chip on a x79 mainboard I think. The Kernel is tricked into thinking it runs on a legitimate Mac product in that case it seems it identifies itself with some ID string of an Air.
So basically his 4600 results are higher than actual Air benchmarks because they're in a desktop chip, no?
An HD 4000 beats the HD 5000 in OpenGL cinebench if you compare it to the high TDP chips. On a 4760K with its TDP the EU can run at the fastest clock rate all the time with a powerful CPU behind it and looking at the Geekbench results probably some fast memory.
HD 5000 in the Air may have 40EUs but it is fairly slow because it just cannot run them at high clock rates for a longer period of time.
OpenGL Cinebench performance has always been quite a lot better in OSX. May just be Mavericks adds even more of a lead. On Windows Intel probably focuses on DirectX most of its efforts for understandable reasons.

I do think Iris Pro's performance (in terms of tests and benchmarks) will be stronger in OSx but I don't think it'll be more than 5-15%. Even so, I don't see any other option than to assume it will be roughly the same, or up to 15% faster than the previous model (and weaker in some situations - cus it's iGPU).
That's basically the only viable option of thought at this point.
Unless they do put a dGPU in there as well, in which case it might get up to 30% faster than 650M. But very unlikely

I'm getting desperate here guys. I'm about to pull the trigger on the 15" rMBP (Again). Talk me out of it, please. It's my only chance.
