Huhm, I'll run it when I get home on my 2.5, currently @ work.

Native res of a 17" requires the 1gb version, for the 15 it's worth it if you upgrade screen res or use an external monitor.
Got a tip for us?

I think especially for Skyrim, 1Gb is a must. When i am running through the forest in Skyrim, i am using about 780MB of gpu memory. (No texture packs)
I suppose if you install some texture mods, this can easily be doubled...
What are your clocks by the way ? I am running it at 800/960 and i cant maintain ultra. Shadows on ultra will kill the fps. With some decent tweaks i can run it nicely though, even with the enhanced shaders mod
Great thread.
I'd be keen on your thoughts.
Purchasing a new MBP and can't decide between models.
As a photographer I'm using multiple programs at once with gigs of images (bridge, photoshop, Lightroom etc.)
Retouching gets done on 27"iMac, so this will be a shoot to on location.
13" is too little so would have to be 15 or 17".
Do I go basic 2.2 15" or do I go 2.4 17" with anti glare?
Will I need 1gig graphics or will 512mb more than handle the job for the next 2.5 years?
Cheers.

I suspect Apple's buy price just went down sufficiently on the 2.4ghz / 6770 GPU enough to swap to those for no manufacturing cost increase.
Performance increase will be minimal, as said you'd be mad to go from early to late 2011 as an upgrade.
Wait for ivy bridge machines or the next model after that to get a decent improvement.

The amount of VRAM will make a negligible (if any) difference to photography applications. It's texture heavy 3D applications such as games that will reap the benefit.
Not an upgrade. Had a silver key 07 17" MBP die on me in December.
Thanks, maybe the basic 15" will handle it my needs fine. So it's more the RAM that needs upgrading?
Would anyone mind clearing up to me why between the Early-2011 high end 15" AMD Radeon HD 6750M and the new Late-2011 baseline 15" 6750M, the vRAMs are different? The earlier one had 1GB while the new one has only 512MB
The previous base model had 256mb (6490). the new base model (now 6750) has double that.
the new high end has 1gb just like the old high end.
Same here. Ive got the high[er] end, 11 MBP 15 with a 1GB 6750, but they later offered that as the base GPU with 512 and the 6770 as the high end GPU option (with the high end CPU).
The memory speed is wrong on the 6770M. Both 6750M and 6770M are 900MHz clock doubled (i.e. effective 1800MHZ). I seem to recall notebookcheck have it wrong on their website and everyone keeps blindly quoting it.
Obviously the refurb is better, as the GPU and CPU are both better.
Remember, if you're really concerned about GPU performance, and you play games in Windows, it's a simple task to overclock the 6750M by a good 20-30%, well above the speed of the 6770M.
Kind of wondering what GPU they might use for the 2012 model.
I hope to see a significant improvement but 6870M or around there.

Yes, that upgrade would be worth it. Double the VRAM (more on the early 2011s with the 6750) and the GPU has 3x as many stream processors or something (from memory, wiki it).
The performance gap between 6490 and 6750 is big (it is an architecture change). 6750 to 6770 not so much at all (its just a minor clock speed bump).
Agreed, also with the 6750 you can easily under volt and over clock it to reach 6770m if not greater speeds.
Hmm well my 6750 1gb on 3d Mark 03 scored a 31134 with the Core and Memory 775/975 respectively at .955v.
I have the early 17" with the 2.3ghz i7 (2820qm) and 8gb 1866mhz Hyper X.
Where did you find those results? Could it be the 512mb 6750m?
This was prob not done on MBP.
Here is the link for the test results.

I'm sure the 2820qm in my machine is what also made up for the difference. I can't imagine seeing the 6770m being more than an over clocked version of the 6750m. Maybe the 6750 is an under clocked version of the 6770? Either way, the only way you can truly compare the two, is by actually getting benchmarks from the GPU's inside the MBP.
Everymac.com should compile lists of benchmarks for each machine, besides geek bench. Even at that, they should have a link to the Geekbench scores and the detailed information to what made the scores up.

Thats actually interesting. The 6750M overclocked is basically 6770M. Or thats what I heard. Im too scared to even overclock my GPU XP
