Apple unveils 2010 MacBook Pro upgrades

The 13in model now incorporates Nvidia's GeForce 320M graphics, while the 15in and 17in versions feature Intel's Core i5 and i7 processors.

The 13in MacBook Pro sports an Intel Core 2 Duo processor and 4GB RAM, and is available in two configurations. One has a 2.4GHz processor and 250GB hard drive that cost $1,499. The other has a 2.66GHz processor and a 320GB hard drive priced at $1,899.

All 15in and 17in models have Nvidia's GeForce GT 330M dual graphics processors, and use Apple's automatic graphics switching technology which toggles between the GeForce GT 330M and Intel's integrated HD graphics depending on performance needs.

The 15in MacBook Pro has three models starting from $2,199 and rising to $2,798, while the 17in model has just one configuration and costs $2,899.

"The new MacBook Pro is as advanced on the inside as it is stunning on the outside," said Philip Schiller, Apple's senior vice president of worldwide product marketing.

"With faster processors, amazing graphics and up to three more hours of battery life, the new MacBook Pro delivers both performance and efficiency."

All models are available now though Apple resellers and the Apple Store.
