Graphics Card in rMBP

[phsphoenix]

It sounds like Chazz08 wants someone to tell him/her what exactly he/she wants to hear for some purchasing decisions. As the second poster pointed out in this thread, the 750m has been benchmarked to death on at a lot of places, and there have been LOTS of discussions about it, even on this forum, and I've even posted a few of them. If you're too lazy to do a search in this forum for the responses on this gpu (some of them less than a month old) I don't think I should be repeating what I said about it, several times in fact.

Edit: Also, we can't give you the exact answer that I feel that you are looking for. At the end of the day you have to make the purchasing decision yourself.

So after all that your question really wasn't this,



but this?



Definitely completely different questions, and your last question is definitely valid and interesting, but have you come across this in your searches?

Automatic graphics switching [macrumors]

No "dual rendering" [macrumors]

No "task combining" [macrumors]

What the Iris Pro is still good for when the 750m is being used [reddit]

Haswell's 128MB of eDRAM - "L4 cache" [cnet]

And if you still want people's "first hand experience" of how CPU requests that are bumped from Haswell's L3 cache are handled by Crystalwell's 128MB of L4 cache while the 750m is switched on, good luck.

It was my question from the beginning, but I guess it wasn't clear enough. I said, "The NVIDIA GeForce GT 750M with 2GB is coupled with the Intel Iris Pro graphics...." I can see how that would cause a little bit of confusion as to the precise question. I actually didn't come across those. Thanks for he input. I didn't word my searches in such was as to show "automatic switching", "dual rendering", or "task combining". Thanks a ton! I didn't even think of that terminology. Thanks a ton man.

Glad that was closer to what you were looking for - and fwiw, it was just searches for "Iris Pro and 750m" and "Iris Pro 128mb cache" and "automatic switching". Searches, and a lot of reading.
