Apple has slightly improved the specifications of its MacBook Pro lineup with faster processors, greater storage and upgraded graphics processors. For starters, the processor speed of the 13-inchers has been bumped by 0.1 GHz, while the 15-inchers and 17-incher got a 0.2 GHz bump. Storage for both low- and high-end 13-inchers has also been upgraded, from 320GB to 500GB for the former and 500GB to 750GB for the latter. Graphics processor upgrades are only available on larger screen models. The graphics processor for the low-end 15-incher has been upgraded from AMD's Radeon HD 6490M with 256MB GDDR5 to Radeon HD 6759M with 512MB GDDR5. The higher end 15-incher and 17-incher both feature a Radeon HD 6770M with 1GB GDDR5. Prices and laptop design remain unchanged.
