Intel Core i5 and i7 processors.

Up to 2x faster at the core.
New quad-core Intel Core i7 processors are standard on the 15- and 17-inch MacBook Pro. And the 13-inch models feature the new dual-core Intel Core i5 processor or the fastest dual-core processor available — the Intel Core i7. All the models use Intel’s recently refined chipsets. So what does all that mean for the new MacBook Pro models? Bottom line: They perform up to twice as fast as the previous generation,1 breezing through demanding tasks like editing HD video, compiling audio or rendering a multilayered image file. And since Mac OS X Snow Leopard is designed to take advantage of every processor core, it captures every last bit of performance from the processor.
Faster single-chip microarchitecture.
Whether you’re watching a video, updating your blog or editing photos, data has to travel from place to place to be processed. The latest Intel Core architecture puts the processor, cache, memory controller and graphics engine on a single chip. Since data doesn’t have as far to travel, you get faster performance and greater efficiency.
Turbo Boost 2.0.
Say you’re using a processor-intensive application like Aperture 3 or Final Cut Pro that benefits from extra power. Turbo Boost is a dynamic performance technology that automatically increases the speed of the active cores — up to 3.4GHz. Turbo Boost 2.0 is even more dynamic and efficient. By shifting core frequency in smaller increments than before, it allows the processor to manage performance without sacrificing efficiency. All this takes place behind the scenes, so your work just goes smoother and faster.
Hyper-Threading.
Hyper-Threading is now standard on every MacBook Pro. This technology allows two threads to run simultaneously on each core, so Mac OS X recognises eight virtual cores on a quad-core processor and four on a dual-core processor. When you’re running multiple applications at once, the processor spreads tasks more evenly across a greater number of cores.
