How fast are the "Mid-2009" 13-Inch, 15-Inch, and 17-Inch MacBook Pro Core 2 Duo models compared to one another? How fast are they compared to the models each replaced?
Quickly review comparisons of the "Mid-2009" 13-Inch, 15-Inch, and 17-InchMacBook Pro models to the models that each replaced and it becomes readily apparent that there are significant changes in connectivity and battery life, but the internal architectures are essentially identical from a performance standpoint with only modest increases in processor speed.
Consequently, one would expect the performance increase to be modest -- essentially corresponding to the percentage difference in clockspeed between models. For the precise difference, however, real-world testing is required.
In its trilogy of reviews of the "Mid-2009" 13-Inch, 15-Inch, and 17-Inch MacBook Pro line, the industry-standard MacWorld ran Speedmark version 5 tests -- the publication's standard test suite -- as well as Photoshop tests while using the GeForce 9600M GT graphics processor and reported.... http://bit.ly/ISwwx
