Performance question: rMBP late 2013 / mid 2014 w/o dGPU

Postby jd-photography » Tue Sep 02, 2014 12:22 pm

Dear all,

I am currently looking for a new MacBook Pro Retina 15 inch and am not sure whether to get the model with oder without dGPU (Nivida Geforce GT750M). The smaller one does "only" have the CPU built-in Iris Pro, which is sometimes faster compared to the Nvidia one. Does anyone of you have experience and could maybe provide some benchmark (rendering images w/o dGPU; overall performance) within CO?

Your feedback is highly appreciated!

Thanks in advance,
Joerg

Basically you should be looking for benchmarks that measures the OpenCL performance.

Here is a page that does just that: http://compubench.com

Hi Christian,

thanks a lot for your quick reply! I have compared both parts on the mentioned site and it says Iris Pro should be superior to GT 750M when it comes to OpenCL. Thats a valueable information. However, I would love to hear from somebody here how C1 rates both models in its internal tests which can be found in the logs file (as mentioned in this thread viewtopic.php?f=46&t=15670). I have learned there that Iris Pro gives a value of 0.833680, now it would be great to have this value for the GT 750M, too.

Anyone?

Kind regards,
Joerg
