So I just unboxed my new 2012 13 inch pro and noticed the graphics was saying 384MB and thought it was going to be 512MB.

Anyhow, a couple of updates and reboots later and now it says 512MB.

Am I going mad??
 
Nope. Just bought one and noticed the very same thing. I wasn't expecting the increase until I added RAM.

13" or 15"?

My 15" has 16GB RAM but has only ever said 512MB. I suppose it would make more sense on the 13", since on a 15" you would just switch to the dedicated GPU rather than allocate more memory to the integrated one...

Same. 15" Retina with 16GB RAM. System profiler shows 512MB VRAM for the Intel card.

More VRAM could definitely help, especially with the high resolution display and graphics assets.

Installed 16gb of ram into my 2012 13" pro, which came with 4gb.

When running an external display on 4GB, it would read 512mb on the integrated video card.

After installing 16gb, it always reads 512mb regardless of external display or not.

The "MacBook Air and MacBook Pro Update 2.0" that Apple released a little while ago upped the VRAM. I think that's the cause of your confusion lol
 
I have found that it really depends on the model after version 2.0. HD 4000 reserves a specific amount. It is not limited to the amount reserved. HD 3000 was specific in how much system memory you had to what was given the iGPU. HD 4000 is more blurry. My cMBP had 8GB and 512MB iGPU reserved now it has 16GB and after 2.0 update only reserves 384MB. 13" with only HD 4000 added reserves amount as did the retina. Because of the GT650m turning on whenever anything demanding or even external display is connected I assume Apple decided you don't really need more than 384MB to move 1440x900. Then again my 15" cMBP must be the only Macbook on the line that lost memory:(
Can't tell a lick of difference.

My Intel HD 4000 wich is supposedly 512mb at stock but when I upgraded to Mountain Lion 10.8.2 and some updates through apple store, my Intel HD 4000 is now 384mb :confused:
