Apple 3GHz iMac
On the fifth anniversary of iTunes, Apple Monday morning introduced a major performance upgrade to the iMac that marks the first refresh since the aluminum design was introduced in August of last year. Every system uses Core 2 Duo processors based on Intel's new 45 nanometer Penryn architecture and in many cases go beyond Intel's maximum speeds: all models include a 1,066MHz system bus that is still unavailable on any official mobile Core 2 chip, and the top-end model runs at 3.06GHz. All additionally include a larger 6MB of Level 2 cache, while an optional GeForce 8800 GS provides faster 3D for gaming on the 24-inch models.
Prices are the same as before and start at $1,199 for a 2.4GHz, 20-inch system with 1GB of memory, a 250GB hard drive, a Superdrive, and ATI Radeon HD 2400 XT video with 128MB of memory. Moving to the $1,499 mid-range 20-inch model boosts speed to 2.66GHz while doubling memory to 2GB, increasing storage to 320GB, and adding a 256MB Radeon HD 2600 XT for graphics. A $1,799 24-inch model ramps clock rates up to 2.8GHz while keeping its same specifications. A special-order 3.06GHz model at $2,199 adds the GeForce 8800 GS video as well as a 500GB drive. All are available immediately from the online Apple Store.
