I dont understand how you could possible want the rMBP to ditch the dGPU, you are literally asking to get ripped off! No improvements would have been made if they ditch the dGPU to only have the Iris Pro. I would rather have a HD graphics 4600 + dGPU as the 4600 is already better than lasts years iGPU and putting a newer dGPU in from the 7xx series.

Iris pro 5200 would be perfect for the 13inch but for the 15inch... thats just ridiculous.

P.s. FIRST POST WOO :D

13" is going to be dual core. Iris Pro isn't on dual core as far as I know.

Dropping the dGPU would extend battery life, use less PCB, and have more room for battery.

Plus iGPU can use system RAM for functions.

I suppose the 13inch could have the 5100?

Extend the battery life, but for battery life you have the Air and even the 13inch, also I doubt the battery life would increase spectacularly.

I believe the system ram has to be accessed through the CPU slowing down the process? Also isn't the system ram usually slower than VRAM?

It's supposedly the 5100 in the 13". 5200 in the 15". But we won't know yet.

And battery life is battery life. If you increase it by two hours, some people go nuts. I'm content with the 7 hours the 15" gets because I rarely am gone for that long.

And DRAM is slower than VRAM, but if you have 8GB of DRAM, you could theoretically use any RAM that isn't used by the system + iGPU integrated RAM.

This Acer has a 750M with 4GB of DDR3. It was over clocked, but you're also using a Dual Core CPU that is under the U brand. 16GB of DRAM? You're looking at probably some better performance than you would think. the Iris Pro processors support up to 32GB. Doubt we'd get that much in a rMBP, but if we did, that performance could go up even more.

It's these other slim notebooks with dGPUs that really make it hard to swallow the idea that Apple wouldn't utilize one. Especially notebooks like the Dell M3800.. it doesn't seem like any other manufacturer is going iGPU-only for their high-end machines..

I realize this is kind of off-topic, but I've looked at both of those and I'm wondering: Why are all the non-Apple laptops using 16:9? That's a terrible laptop ratio. Any real work needs vertical space, not so much horizontal, and 19:10 is a great compromise for reasonable form factor and extra vertical area. Is the assumption really that people are only watching content and playing games at this point?

Vertical space is actually quite useful in Ableton Live (and while I don't use other daws I'm guessing it's equally useful in programs like Reason, Logic and Pro Tools)

I'm not even that sure if it's that much better than the 650 in real life usage, but even if it is, the 650 is outdated anyway. A 760 would blow the 5200 away (I'm guessing).

What about the AMD crystal series? I know they have some new mobile releases.

I haven't actually read anything about the new AMD cards, but as Apple has had ati cards in Macbooks before, I wouldn't rule out the possibility.
 
Those AMD GPUs are 20nm and they won't arrive in time. 20nm production is definitely not there yet. If they release anything, it will be the one test low volume test chip.

Yeah but a lot of these slim notebooks don't have long battery lifes. You get different scenarios.

Great Battery + decent graphics + bad screen (resolution, TN, or both)
Great battery + sub-par graphics + alright screen (resolution, IPS, or both)
Bad battery + great graphics + alright to great screen (resolution, IPS, or both)

Ultrabooks are pretty much great battery + good screen + sub par graphics
Gaming laptops are bad battery + alright to great screen + great graphics.

MacBook Air is basically an ultrabook (except it has a meh screen. Looks great, but it's still TN and low resolution)
MacBook Pro is between the two obviously. Pretty good battery, decent graphics, great screen.

Apple can either a) get better graphics and sacrifice battery. b) better battery and have the same decent graphics.

The second option seems more than likely.

OpenCL support is pretty limited. Every game developer will experience worse performance, every 3d artist will experience worse performance because these things need fast OpenGL.

The only Pros that will clearly benefit are those doing video editing. Everyone else will experience worse performance.

This is why I'm hoping against hope that Apple keeps a good dGPU option.. if not for gamers then for 3D design.
 
15" rMBP will have dGPU because apple probably will want great battery life.
-if they put only Iris Pro, that iGPU will work probably 90% of time and eat a lot of battery
-if they put dGPU, when you are using the macbook for light usage, only the HD 4600 will be used so great battery life

The only OpenGL benchmark that is often tested is Cinebench and the new Intel drivers do quite well in that one.
The HD 4600 benches at 27fps. The 650M at 42fps. That is Windows but there are some OSX benches out there too and Intel still comes in well over 20fps.
An HD 5200 could break a 650M there.
https://pikeralpha.wordpress.com/author/pikeralpha/page/2/
Not sure what is going on here but a desktop hd 4600 hackintosh runs number the mobile 650M usually gets in OSX.
I just don't see where Intel's supposed bad OpenGL performance is.
Support for all the newest OpenGL features under OSX has been mediocre on the Nvidia and AMD front just as well, because it is not Nvidia and AMD supplying the newest drivers and Apple never seemed to be fond of staying up to date.

Yes OpenGL performance is actuall better in OSX in Cinebench.
http://www.notebookcheck.com/Test-Apple-MacBook-Air-13-Mid-2013-MD760D-A-Subnotebook.94094.0.html
Probably because Nvidia reserves good OpenGL performance in Windows for the Quadro line only and deliberately cripples the Geforce somewhat. That is a HD 5000 which usually yields barely any more than a 4400. What do you think a 5200 can do in that benchmark in OSX.

A geforce 750M 1G vRAM will fit better a 15" laptop than iris pro, in performance and battery life.
 
Wow, this is about as hotly contested a topic as I've ever seen. 200 votes and practically split down the middle! Can't wait for the reveal.

Split down the middle between both month release and dGPU! :cool:

Seriously, where are all of those "my professional needs will suffer from Apple not including the gaming dGPU into the next rMBPs" guys creeping out from?
From my professional requirements POV, I really hope, they'll DO include an Iris Pro into the next 15" rMBP. You can always go and buy some Alienware laptop with gaming graphics and do your professional work on it.

More odd than someone who thinks GPUs are only used for games?

Nope. It is also used for GPGPU, in which, if we look at Anand's article, Iris Pro beats nvidia mobile gaming GPUs by a margin. What else could be GPU used for? For 3d graphics work? A MOBILE GAMING GPU? If that's your argument, I'll laugh at your face, I promise.
