You?ve dreamed about it long enough. Now it has a name: MacBook Pro. Powered by a dual-core Intel engine. Up to four times the speed of the PowerBook G4. Eight times the graphics bandwidth. With built-in iSight for instant video conferencing on the move. And Front Row with Apple Remote to dazzle everyone in the room. Wait no more. MacBook Pro starts at just $1999.
New engine, same soul
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.
