The MacBook Pro (17-inch), MacBook Pro (17-inch Core 2 Duo), and MacBook Pro (17-inch 2.4/2.2GHz) represent three generations of the MacBook Pro professional notebooks. The original MacBook Pro (17-inch) is based on the Intel Core Duo chip, while the latter two MacBook Pros (17-inch Core 2 Duo and 17-inch 2.4/2.2GHz) are based upon two successive iterations of the more recent Intel Core 2 Duo chip, with the latest increasing processor speeds from 2.33GHz to 2.4GHz.
The newest MacBook Pro (2.4/2.2GHz) supercedes the previous MacBook Pro (17-inch) models in four ways: the bus speed has increased to 800MHz, the system now addresses up to 4 GBs of RAM, it sports a new NVIDIA GeForce 8600M GT graphics chip, and can come configured-to-order with a higher resolution 1900 x 1200 (antiglare or glossy) display.
The only outwardly visible difference between the three machines is a small opening in the display bezel for the LED to the right of the iSight camera in the original MacBook Pro (17-inch).
