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,2 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. Performance and expansion never seen on a notebook before. Thunderbolt I/O technology gives you two channels on the same connector with 10 Gbps of throughput in both directions. That makes it ultrafast, and ultraflexible. You can move data to and from peripherals up to 20 times faster than with USB 2.0 and more than 12 times faster than with FireWire 800. You also have more than enough bandwidth to daisy-chain multiple high-speed devices, without using a hub or switch. For example, you can connect several high-performance external disks, a video capture device, and even a Mini DisplayPort display to a single Thunderbolt chain while maintaining maximum throughput.
