The 15-inch model and 17-inch model add switchable dedicated graphics from AMD, ousting the NVIDIA chips that powered the previous lineup. Sandy Bridge obviously integrates Intel’s HD 3000 graphics on die, which is used by all of the new MBPs by default. This makes these two MacBook Pros ripe for a desktop replacement usage model, particularly if paired with an SSD. Both the 15-inch and 17-inch MacBook Pros now feature quad-core CPUs. Sandy Bridge is used across the board and interestingly enough only the 13-inch model uses a dual-core CPU. The move to Sandy Bridge is different - all models got an upgrade. When Apple moved its MacBook Pro lineup to Arrandale, the poor 13-inch model lost out - it remained with an older Core 2 Duo CPU.

No mere speed bump, these new MacBooks bring Intel’s new Sandy Bridge processors chipsets to the entire line, replacing the previous Arrandale processors and finally retiring the aging Core 2 Duo from service in the 13-inch model.Ĭontrary to earlier reports, there are no default SSD configurations although the solid state offerings are still optional. The Apple online store also has immediate availability. Apple retail stores received stock prior to today and began selling product immediately. There was no scheduled press event and nothing more than a press release announcing the specs and availability. The update was unusually quiet for Apple. As expected, Apple today unveiled a range of speed and functionality improvements for its MacBook Pro lineup.
