In an uncharacteristic early morning refresh, Apple on Monday updated the MacBook Pro. The new versions use slightly upgraded processors, up 100MHz on 13-inch models to 2.4GHz Core i5 and 2.8GHz Core i7 chips and 200MHz to 2.2GHz and 2.4GHz on 15- and 17-inch models. Video has also been given a boost: the base 15-inch now uses a much faster Radeon HD 6750M with 512MB of RAM, up from a 6490M with 256MB of RAM, while the higher-end 15-inch and 17-inch models use a 6770M with 1GB of RAM.
