Next-generation quad-core and dual-core Intel processors.
The 13-inch MacBook Pro now features a 2.3GHz Intel Core i5 processor or the fastest dual-core processor available — the 2.7GHz Intel Core i7. With Turbo Boost speeds up to 3.4GHz, these processors allow the 13-inch MacBook Pro to perform up to twice as fast as the previous generation.
But we couldn’t leave fast alone. The new 15- and 17-inch models bring quad-core power to almost everything you do. The available 2.3GHz quad-core Intel Core i7 processor — with Turbo Boost speeds up to 3.4GHz and up to 8MB of shared L3 cache — enables these MacBook Pro models to run applications up to twice as fast as their top-of-the-line predecessors.
