AMD Radeon HD 6750M VS 6770M

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
Yes, but the new one is hundreds of dollars cheaper, while the only difference is that it has half the VRAM.
You will only need the 1GB when gaming at much higher resolutions. If your gaming at 1440x900 then 1GB will provide a very insignificant FPS increase from the 512Mb. You can just overclock the 6750 and there will be little difference between the two cards at 1440x900. I would say 2-3FPS.
The world is bigger than the gaming world... everyone but the best gamers are a waste of time and resources. And by the way. VRAM wouldn't significantly affect games much at all given there's a 'generous' amount.

It's cheaper! Apple also stepped back slightly on the CPU model (comparing the late 2011 entry level against the early 2011 mid model) for one with a lower turbo boost speed. Given that it's $/£hundreds cheaper and it's got a much quicker graphics card than the old entry level model I ain't complaining.
Off to play with my 2.2GHz now...
If you are concerned the low VRAM, cant you get 16GB DDR3 and get like 1GB of intel HD 3000?
I have 8GB right now and I got 512MB.
But to be honest just for the slight CPU and GPU bump, buying a late 2011 MBP is pure stupidity if you already have the early 2011.

512MB GDDR5 are not really that expensive. They cost Apple probably some 20 bucks at the most.
The 6750 new has 512MB so people feel the need to pay up and get the more expensive 15" as otherwise the difference between 6750 and 6770 is pretty much non existent.
I'd recommend getting the 1GB one. Textures are loaded to the VRAM, and if you plan on playing in 1080p, you'll definetly need more VRAM than in the standard 1440x900 resolution. Depends on the game you're playing though.
Vram is not about fps, it's about loading higher texture quality. With the 1gb version you can simply load higher quality textures.
Not games but video editing?
I see everyone talking about game performance but I am interested in using the macbook pro to edit video in the AVCHD format which can be a serious drain on resources. I would like to know if anyone thinks the 6750M could handle it with ease or the 6770M is the one to go with? thoughts, ideas? Thanks for the input.

6750 can do that in it's sleep. The extra 10% clock speed of the 6770 is handy for chucking polygons around in COD and that's about it. I seriously doubt for video editing you'd notice any difference between the cut down 6490 in the early 2011 and the 6770.
512MB will be fine. The additional VRAM is utilised for massive high-res textures, usually in gaming and even then it only makes a couple of % difference.
Ive got the early 2011 base model 15" w/ the 6490M w/ only 256MB VRAM. I bought it about three months ago, and these newer versions are very tempting. I play a decent amount of games on my MBP thru Bootcamp (BF3-low settings, Skyrim-Low settings, etc) and they all play pretty well when put on low settings. BUT, I could really use a better GPU.
Would it be worth it to sell my MBP and get the newer, base model 15" MBP? I see that the GPU is only increased by half (512MB instead of 256MB), but the CPU is now 2.2GHz instead of 2.0GHz. I know, not MUCH of a difference. But I kind of regret it now =/
What do you all think?

That is partly true but when you run out of vram at any given texture size or quality, it your FPS take a hit and the only option is to back down on the settings.
To the OP, I think most games will run fine on 512mb, just not great. If it really bothers you, you can still get the early 2011 midrange model with the 6750 that has 1gb for just under the price of the current entry level if you are willing to go refurb. I'm running Skyrim at most settings higher than the "Ultra" preset with the older 6750.
