MBP 2.66 i7 15" = 'mid 2010' 15" MacBook Pro Core i7 2.66GHz with GeForce GT 330M (512MB GDDR3)
MBP 2.53 i5 15" = 'mid 2010' 15" MacBook Pro Core i5 2.53GHz with GeForce GT 330M (256MB GDDR3)
MBP 2.66 c2d 13" = 'mid 2010' 13" MacBooK Pro Core 2 Duo 2.66GHz with GeForce 320M (256MB GDDR2 SDRAM shared with main memory)
MBP 2.60 c2d 15" = 'early 2008' 15" MacBook Pro Core 2 Duo 2.6GHz with GeForce 8600M GT (512MB GDDR3)
All test units had 4GB of SDRAM and were running OS X Snow Leopard.
WHAT DID WE LEARN?
The 'mid 2010' Core i5 and Core i7 MacBook Pros are significantly faster than the 2008, 2009, and 2010 Core 2 Duo based MacBook Pros whether crunching with the CPU or stressing with the GPU.
If you are on a limited budget, you might consider a used or refurbished 2008 or 2009 Core 2 Duo MacBook Pro since its standalone GPU is stronger than the integrated GeForce 320M used in the 2010 Core 2 Duo MacBook Pros.
We included the Core i5 MacBook Pro in the CPU crunch tests but left it out of the GPU tests. For one thing, when we tested it at higher resolutions, it scored essentially the same as the Core i7 model (since they share the same GPU). For another thing, we forgot to test it at 1280x800 before we returned the borrowed unit. ;-)
