Yes. Substantially and significantly.
Does the 750m outperform the Iris pro in Open CL? Open GL for sure...
Yes. Substantially and significantly.
Its mind boggling that Apple still has 4GB has a stock option on a Macbook Pro. My 2008 non-unibody Macbook Pro has 4 GB and it isn't enough.
I think they screwed up the specs page. The other explanation doesn't make any sense. Currently:
Base model without dGPU ($1999) + 2,3Ghz + 16GB Ram + 512GB flash = $2599
Top-end model with dGPU = $2599
In addition, we had those leaks from that chinese website which turned out to be spot on. Those only spoke of three versions: 2,0Ghz without dGPU and 2,3Ghz/2,6Ghz with dGPU.
Thanks...now if anyone can confirm with new MacBook Pros if they were successful with a 15% deal via employee purchase, that would be awesome

Just placed and order for mine delivery date 24th october.![]()
Sigh. I've ordered a 13 i7/16/1TB.
Can't help but think that processor sounds under powered, but we'll see I guess.
I'm really not sure, looking at the updates, if it's worth just getting a cMBP and adding RAM and (possibly) boosting the processor.
cMBP with 8GB RAM = £927
rMBP with 8GB RAM = £1014

I'm a musician. The retina display means little to me and I'll be using external HDs to save everything..
Is upgrading/maxing the possessors worth it?

Questions (this will be my first time ordering online/over the phone with Apple.)
Am I correct in thinking that if you want a processor upgrade, you have to order online or over the phone?
Thinking that I won't need the 16GB RAM, so planning on ordering it with 8. If I find that I do need the 16GB, are returns still allowed as it would be a customised machine because of the processor? If yes, can you return to an Apple Store or do you have to pay for a courier and insurance?
Finally, I'm a student but currently away from the university campus. Guessing that I would have to order over the phone or wait until I am on campus to order in order to receive the discount?
Thanks all
Iris Pro has more ALU (= programmable unit performance) at a higher clock speed than the 750m. It also has much(!) more low-latency, high-bandwidth cache available than the 750m. The 750m, on the other hand, has much more TUs (texturing units) and ROPs (Pixel backends).
In theory, the Iris Po should be much better at GPGPU (OpenCL), while the 750m should be, on average, better at rendering. That is what all the benchmarks have shown so far. It is also generally known that nVidias Kepler architecture (at least in the variant used in the 650m/750m) is relatively weak at GPGPU (OpenCL/CUDA).
Your line of reasoning is presumptive. Those BTO options are hugely profitable, but many consumers purchase only one or two. Sales on high-end models also lag. It's entirely possible that the whole idea here to offer a "bundle" of features that appear to be at a discount from their disaggregated prices, with the goal of getting more users to upgrade to the higher-end configuration. Apple still gets more profit dollars (and margin percentages, too), while letting users think they've gotten a "better deal." We've already seen some people in this thread believing that very thing.
In short, rather than assuming it doesn't make sense, an alternative hypothesis is that it's clever, projections-based marketing.
24th?! Where do you live! Mine says 29th, i'm in Montreal, Canada
....Not worth the savings, IMO.

no it's not, there s a usb 3 port on it so you can always add another hard drive

That's a crazy statement. The dGPU is clearly the better option, especially as implemented.
