VRAM on 13" rMBP

[Naimfan]

I don't know if anyone else has commented on it, but the 13" rMBP uses 768 MB of RAM for the HD4000; compared to 512 MB for cMBP.

Is the extra RAM used to help the HD4000 drive the screen more easily?

I'm pretty sure it is.

That's actually a lot of VRAM for the IC on your MBP. Not sure if that's normal or not. It will definitely help on graphics performance, specially with that amount of pixels to drive.
