Up to 2x faster at the core. New quad-core Intel Core i7 processors are standard on the 15- and 17-inch MacBook Pro. 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, 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. Introducing Thunderbolt. The fastest, most versatile I/O ever in a notebook. Imagine accessing multiple streams of uncompressed HD video - from notebook - at speeds that let you edit an HD feature film in real time. That's how Thunderbolt technology will connect the next generation of high-performance peripherals to the next generation of computers - starting with MacBook Pro. Ultrafast and ultraflexible, the Thunderbolt pipeline is up to 12 times faster than FireWire 800 and up to 20 times faster than USB 2.0, and it offers unprecedented expansion capabilities. It changes what you can do on a notebook. A long-lasting battery. Charge less. Do more. The new MacBook Pro delivers amazing battery life. And that’s with more powerful processors and faster graphics. An energy-efficient processor architecture with an integrated video encoder, along with automatic graphics switching in the 15- and 17-inch models, all help improve battery life. So you can expect to surf the web wirelessly for up to 7 hours on a single charge. Up to 2x quicker on the draw. And the render. When you need more performance for things like playing 3D games, editing HD video, or even running CAD software, the 15- and 17-inch MacBook Pro models automatically switch to discrete AMD Radeon graphics that let you see more frames per second and experience better responsiveness. With up to 1GB of dedicated GDDR5 video memory, these processors provide up to 2x faster performance than the previous generation.
