Comparing 2011 15' MBP to 2012 13' MBP on performance

[willmer]

Given the drop in prices of the 2011 models, I am now interested in the 2011 15' model namely this one http://store.apple.com/us/product/FD318LL/A

Currently the size/weight are not a huge factor for me but the difference in price is a small-medium factor (1199 vs 1359)

So the differences between the 2011 15' and 2012 13' are:

Processor (winner=15'?) I'm not sure what the cache difference means

• 2.2 GHz Quad-core Intel Core i7 with 6MB L3 cache (Sandy-Bridge)
• 2.5GHz dual-core Intel Core i5 processor with 3MB L3 cache (Ivy-Bridge)

Memory (winner = 13' but memory will be cheap when I need to upgrade)

• 4GB (two 2GB SO-DIMMs) of 1333MHz DDR3 SDRAM
• 4GB of 1600MHz DDR3 memory

Graphics (clearly 15' with discrete GPU)

• Intel HD Graphics 3000 with 384MB of DDR3 SDRAM shared with main memory 1and AMD Radeon HD 6750M graphics processor with 512MB of GDDR5 memory
• Intel HD Graphics 4000 (all 13- and 15-inch configurations)

Screen (15' even if you disregard the size difference)

• 15' 1440-by-900 resolution
• 13' 1280 by 800

So it would appear that the 15' from last year would be a much better computer to get than the new 2013, but the price difference plays some factor.

If you are asking what am I using it for, I am planning on having large amounts of data in excel to manage, editing scientific images with multiple channels at high resolutions, some minor gaming. But I would like to keep the computer for at least the next 3 - 4 years and not replace it.

So would you agree that the 15' would be a better computer compared to the new 13'?
