This is the first Mac notebook built upon the revolutionary new Intel Core Duo — which is actually two processors (up to 1.83GHz) engineered onto a single chip. It provides 2MB of Smart Cache, L2 cache that can be shared between both cores as needed. It delivers higher performance in 2D and 3D graphics, video editing, and music encoding. And the new engine is only part of the story. MacBook Pro has a frontside bus and memory that, at 667MHz, runs faster than any previous Mac notebook. It’s the first Mac notebook with PCI Express, a Serial ATA hard drive and the ATI Mobility Radeon X1600 for superfast graphics performance.
