Highlights include ten-hour battery life and NVIDIA GeForce 320M graphics on the 13-inch model. The 15- and 17-inch models feature GeForce 330M graphics paired with an Intel HD graphics chip, and newer, more powerful Intel Core i5 and Core i7 CPUs.
Interestingly, the Core i7 is only available with the top-of-the-line 15-inch MacBook Pro. The 17-inch model is only available in one configuration, which comes with a 2.53GHz Core i5 processor.
Battery life on the 15- and 17-inch models is rated at 8-9 hours, helped by intelligent graphics switching, which uses the Intel graphics chipset for run-of-the-mill tasks and the NVIDIA graphics chip “for the most demanding 3D games, creative software and technical applications,” according to Apple.
All three sizes are available now. There are two 13-inch configurations, three 15-inch configurations, and one 17-inch configuration.
