I recently had my laptop stolen from work (an old 2.4 ghz Core 2 Duo) and am going to be buying a new MacBook Pro with the insurance money.

Does anyone have a comparison of the two versions of the 15"? I can't find them anywhere. I'm talking about the late 2011 ones that were just updated about two weeks ago.

I just can't decide if I should throw down another 200 dollars for the one with higher specs.

Thanks in advance.

You need to tell us what are you planning to do with the Mac.

I wouldn't give the 0.2 GHz much importance. What I would give more importance is to the extra 512mb in video memory.
 
I work with a lot of Photoshop and Illustrator at work, and I do a game quite a bit in my free time. I just don't know how much better the processor and graphics card is compared to the lower end model.

Benchmarks anyone?

Go with the 2.4Ghz. The 6770M will get you a few more FPS over the 2.2Ghz's 6750M. But most important is the 1GB of VRAM.

If you are looking to save a buck consider the last gen 2.2Ghz or last gen 2.3 which has a 6750M with a 1GB of VRAM
 
The 6770M has about 80% better memory processing power and 15-20% better pixel pushing power than the 1GB 6750M.

The 0.2 GHz isn't the big thing between the two processors. Usually, there's a difference in bus speeds and L2/L3 cache.

I'm sorry, but the 6770M is a very marginal "upgrade" over the 6750M. The difference would not be noticeable.

I agree, where are you getting this 80%? or the 15-20%?

^That is true. The recommended memory clock (by AMD) is for both cards the same, 900MHz. Apple underclocks their cards anyway. In case of the 6750m they underclocked it to 794Mhz.

On notebookcheck.com the memory clock of the 6770m is listed as 1600Mhz. On Wikipedia it is listed as 900Mhz, which is the same as the 6750m. Notebookcheck.com must be wrong, because even the 6970m has only 900Mhz.

My guess is notebookcheck.net. They've got the 6770M sporting 1600MHz memory vs the 6750M at 900MHz. It appears to be an error as AMD themselves specify the entire range at 800-900MHZ range. The main difference is the 600 vs 725MHz core clock assuming that Apple are running them at full speed. Some older ATIs were underclocked to keep the heat down.
