It depends on how much ram you have installed. With 4 gig of ram it will show 384? I believe, and 512 if you upgraded to 8 gigs of ram.

Yes it does. The system sets a side a percentage of whatever amount of ram you have installed. If you add system ram it will set more a side as video memory. When I bought the 13 inch MBP, it only had 4 gigs of ram, and used 384 mb's for video. Once I upgraded to 8 gigs of ram, the system reserved 512 mb's of that for video. I don't know if it will go higher if you install more than 8 gigs though.

Does that mean 8GB of RAM would increase gaming performance?

Gaming performance might improve, or it might just improve the quality of textures loaded during your games. Someone with more knowledge might be able to answer this better than I ever could.

wait does that mean on every 2011 MBP 15" [and possibly 13"] you put in 8GB you get more vRAM for HD3000??

No.

To be pedantic, the HD3000 has no "VRAM." It utilizes some system RAM instead of having dedicated RAM built in to it, or next to it.

The effect, however, is the same--upgrading to 8 GB RAM increases the amount of RAM available for the HD3000 to use.

Mbp 8,2

Hey Guys,

I am the proud owner of the Macbook Pro, and the screenshot etc ;)
Thanks for the info, and Mobius 1 Thanks for posting my question ;)
The 8Gb sounds pretty logical, but its strange Apple doesn't tell customers about this...
When I ordered my Macbook the 348MB didn't change into 512MB when I selected 8GB instead of 4 (double checked).

A buddy of mine has got the latest version iMac 27" which has a Sandy bridge chipset as well, I asked him to instal 8GB and 16GB of RAM, but nothing changed.. This might be because the iMac doesn't have 2 gpu's like my Mbp but it does have a i7 processor which should handle a part of the video performance...

In 1 or 2 months (when I'm sure there are no problems with my mpb) I'm going to open it up and take a look and maybe mod some things etc, so by that time I can try to put just 4GB of RAM in there, to see if it changes my vRAM ;)

Sorry if my English lacks, I'm Dutch ;)

i thought you use the 6750M for gaming?

I'v got a little tool installed called gfxCardStatus, it shows me which gpu i'm using and it lets me switch between them, but I use my mbp on my desk most of the time, so i don't care about power consumption and always use the AMD Radeon gpu ;)
But normally it should automatically switch between them, when i start a game it starts using the Radeon gpu.
But for people that want to constantly use the power efficient gpu while doing some lightweight work the extra 166MB might be pretty cool ;)

Intel HD Graphics 3000 allocates a base amount of 384 MB for video and processes at startup. For example, a MacBook Pro (13-inch, Early 2011) with 4 GB of RAM installed has 3.7 GB of memory available to Mac OS X and applications (4096-384=3712). For portables that have been upgraded to 8 GB of RAM, the Intel HD Graphics 3000 will allocate 512 MB of system memory instead of 384 MB. For example, a MacBook Pro (15-inch, Early 2011) with 8 GB of RAM has 7.6 GB of available memory (8192-512=7680)

It's just a feature that the sandy bridge integrated graphics have. The iMacs use separate AMD graphics with their own graphics memory, so changing the system RAM has no effect on the graphics memory.

The amount of shared video memory is normally dynamically allocated to your integrated graphics processor. It is the maximum that the graphics processor can use out all your available memory, but it doesn't mean it will. For example if I'm running just a few brower windows, it won't need much.
