15" rMBP Base Max vs Top w/Nvidia Max

[thaifood]

It's not logical because it doesn't exist. Although you never know, you and Sdali may be the only ones special enough to have a dGPU w/ your 2.3 and 2.6 base models!

Haha, I agree. It would be readily available information on the specs page and when configuring the BTO. That's why I'm so sceptical

This thread has become moot.

I asked Apple directly and they got back to me.

2.0Ghz is Iris Pro only and 2.3Ghz and 2.6Ghz automatically come with nvidia, regardless of which configuration you start with.

That's why they are the same price. So no 2.6Ghz Iris Pro only.

Please tell us who you asked and if they were credible. Thanks!!

Perhaps for a small servicing fee Sdali will let you speak directly to his inside source at Apple!

Jesus H. Asscrack! Again with this? This is like the third time I've heard this. Can we get some confirmation on this?

from what I can see you can build two identical rMBP's one with and one without the NVIDA.

Newbie question here, but why wouldn't you get the NVIDIA? All the threads leading up to this were pissed that the discrete looked to have been cancelled now there are those who don't want it?

Is it a power saving thing? A heat thing?

I have a 2005 iMac that I am replacing. I am just going to max out the rMBP and go full boat. I figured that would include the NVIDIA. Is that wrong?

All the reviews when the last 15" came out said to wait for the next version because the 650M was too slow for the retina display. Ironically, the Intel Iris Pro is SLOWER than the 650M by a significant margin. Other than to save costs, or if you don't plan to do anything intensive with a $2000 computer, there's no compelling reason to get the Iris Pro.

Basically the Iris Pro 5200 is on par with GT 650M.

And the GT 750M is only 15% better than the GT650M:

http://www.notebookcheck.net/NVIDIA-GeForce-GT-750M.90245.0.html

Honestly, with that information it is almost becomes a no brainer for me.

Why have another chip generating another 35-40 watts, when the integrated chip is good enough?

The 750m rmbp uses GDDR5 with 2gb vram which is a significant improvement from the GDDR3 650m 1gb vram model of last year.

Thanks for breaking it down, you basically just convinced me to go for the base model. I'm sorta in the same situation - getting a 15" for video editing in FCPX and Motion 5, so will need max RAM, but not sure if the slightly increased processor speed (0,3 GHz), +256 Gb SSD and the GT 750M is worth the extra £290 = $471 (I get a nice student discount) - can I get a second opinion on this? Or I'll go with the base model and maxed out RAM.

The 750m comes with 2GB RAM and I edit video as well. Going with dedicated graphics for sure. And you can disable the dedicated graphics and still have iris pro for the SAME PRICE. Makes no sense to get the iris pro only model.

650M used GDDR5, just only 1 GB of it

Thanks - I just logged in to post that!

And let's also remember that the 650M used in the 2012-2013 rMBP was overclocked as standard, and tests (posted on this forum and which I have myself replicated) showed that it could easily be overclocked even further. I routinely run mine at 1100 mHz (core); the chip is usually clocked (at boost) at 950 mHz, while the usual part (as used in other makes of laptop) is clocked at 900 mHz. So the comparison between the 750m and 650m on notebookcheck.net (which reflects a 10-15% improvement with the 750m) may not be valid in this case.

Also, add to that the fact that the 750m is basically a re-branded 650m: the same Fermi core, with slightly higher clocks - and I am happy I bought my second rMBP earlier this year, when I did.

(Please someone correct me if I am misinformed).

I would like to hear from someone with more knowledge whether Thunderbolt 2 will be REQUIRED in order to run a 4K display, or whether the mid 2013 rMBPs will be able to do so, perhaps using both TB1 connections at the same time??

most likely, you'll need TB 2. Theoretically, it could be possible to use 2 TB 1 ports together, but who knows if any vendor would support it.

Ok, new rules then. Would it be brain dead to downgrade to 2.0 GHz to get integrated GPU only?

 

[aiom]

I asked Apple directly and they got back to me.

2.0Ghz is Iris Pro only and 2.3Ghz and 2.6Ghz automatically come with nvidia, regardless of which configuration you start with.

That's why they are the same price. So no 2.6Ghz Iris Pro only.

SERIOUSLY?! HOLY FUGGIN CRAB MUTHAFUGGING SHIDCRABTASTIC, THAT WOULD BE AWESOME.

So I could basically use the Basemodel for 2K and then add $100 for the 2.3Ghz and get the dedicated 750m too?

 

[iKrivetko]

I'd suggest waiting for proper benchmarks and reviews, and making the decision when there is a way to actually compare the two.

Kepler, actually.

A few days. Might even surface today.

I just spoke to Apple in Sweden. The person I talked to in the sales call center told me the upgraded base model does not come with dGPU. BUT, I did not find him credible, the call center in Sweden is probably not 100% updated on the new models and he did not appear to be on top of all the details when I asked more questions.

 

[adildacoolset]

There is no reason at all for you to get the dedicated GPU. The dGPU is mostly for gamers and people doing heavy 3D stuff



So it is.



Would you be so kind to show us some benchmarks? For GPU-assisted workflows, Iris Pro is not any slower than the 750M. It surely has more processing capability. Its only weakness is memory bandwidth.

But wouldn't video editing benefit from the 750M due to CUDA support? AFAIK, a lot of video editing suites don't have OpenCL code paths that are as developed as the CUDA counterparts.

 

[emptysands]

Anyone know if the 750m supports G-sync?

[Ifti]

GET THE 750M you chumps (especially if there is no price difference)... I can't believe we are debating this.

Yes, gfxcardstatus will allow you to permanently disable the dGPU if you ever desire to, so you can squeeze out that extra battery life.

Exactly my thoughts!

 

[PH22]

Just one more thing to consider and correct me if I'm wrong, but in the current generation the BaseCamp drivers can only use the dGPU, right? So, when you get a model with Iris Pro only even the battery life in Windows should be much better than it was (I know this may be only interesting for a minority of users).

 

[bluedoggiant]

Any clarification on this topic?

 

[longshank]

Could anyone in the US please call Apple and clarify if the dGPU is shipped with the 2.3GHz base model upgrade? I guess the staff there is more updated on details than in Europe.

 

[zI INFINITY Iz]

Thanks for the intel bro, but that majorly sucks!!!!! Is there a way to isolate the the dgpu I wonder……I just need the high-end rMBP for CAD and the dgpu is in some cases (solid works) half as fast

You are saying that Solidworks works half as good with a dGPU then with an iGPU? iGPU makes SOLIDWORKS twice as fast? That's what you're saying?

Any proof to back this up? Because if that's true, the base model with Iris Pro only would suddenly become much nicer in my eyes.

 

[lotsoflemon]

I called Apple today, UK edu store. Twice. First woman wasn't shure, said she'd get back to me - never did. Second guy said no, but he was basically just "reading the specifications" from the screen - sounded like he knew nothing more than what it says in the online store...

Anybody from US that could call them? This is actually pretty ridiculous.

 

[monkeydax]

Will upgrading the base model to 2.3GHz be limited by the lack of 16GB RAM?

 

[nosetrick]

This thread has become moot.

I asked Apple directly and they got back to me.

2.0Ghz is Iris Pro only and 2.3Ghz and 2.6Ghz automatically come with nvidia, regardless of which configuration you start with.

That's why they are the same price. So no 2.6Ghz Iris Pro only.

I really wish someone in the US could call apple to confirm this. It's a big deal whether or not this is true!
