Apple's latest MacBook Pro refresh brings us new models across the range. The new 13-inch 2.66GHz and 15-inch 2.66GHz Core i7 model will really impress you..
The 15-inch offers an exciting new graphics technology and a fundamental change of processor architecture. The 13-inch MacBook Pro's update is far more muted, but still very welcome.
The three new 15-inch MacBook Pros move to Intel's new Core-i series processors. The top-of-the-range version reviewed here boasts a 2.66GHz Core-i7 CPU, with 2.4GHz and 2.53GHz Intel Core i5 models also available.
Beyond simple gigahertz ratings, the new chipsets have performance boosting features, making them much faster than the previous 15-inch line-up's 2.53, 2.66 and 2.8GHz Core 2 Duos.
The 2.66GHz Core i7 runs at up to 3.06GHz for dual-core tasks and 3.33GHz when in single-core mode. The new chips also include an integrated memory controller, connecting system memory directly to the processor and removing the separate I/O controller, boosting performance even further.
In contrast, the two new 13-inch MacBook Pros stick with Intel Core 2 Duo processors, offering speeds of 2.4GHz and 2.66GHz, up from 2.26GHz and 2.53GHz respectively. While any speed increase is welcome, using a Core 2 Duo as the rest of the MacBook Pro range moves to the Core-i chipset makes the 13-inch model look a little dated.
