Apple updates MacBook Pros with Core i5, i7 processors.
The 15-inch and 17-inch MacBook Pros saw the biggest jumps, as they now use Intel’s Core i5 and i7 processors. Designed with a 32-nanometer process, the Core i5 and i7 sport integrated memory controllers and Level 3 caches. A Turbo Boost feature lets the dual processor cores optimize their performance, allowing speeds of up to 3.06GHz for dual core tasks, and 3.33GHz for tasks involving just one core.
As with the previous iterations, both the 15-inch and 17-inch MacBook Pro models feature two graphics processors, in this case the Nvidia GeForce GT330M for high-performance needs and the Intel HD graphics for more power efficiency. And in an improvement over the last generation, Apple says the system will automatically figure out which graphics processor is needed for a program or operation, and switch as necessary to give you both the best in performance and battery life. In the past you had to go into System Preferences, choose a graphics option, and log out and back in for the change to take effect.
“We wanted to make the process much more seamless for the user,” a representative told us during a briefing on the Apple campus Tuesday. To that end, the company made it so the Macs intelligently switch between integrated and discrete graphics as needed.
