Join our MacBook Group.The 1.83 GHz model retains a 2 MB cache, Combo drive, 60 GB hard drive, and 512 MB of RAM. The basic computer remains the same, but the 2.0 GHz models include a twice-as-large 4 MB level 2 cache, 6x dual-layer SuperDrives, larger hard drives, and 1 GB of RAM. There’s no change to CPU speed, but the more efficient Core 2 design means a faster MacBook at the same price as the model it replaces. Overall, that should provide about 10% more power. Now that Apple has solved most of the MacBook’s teething problems, they’ve improved it by replacing the Intel Core Duo CPU with the newer, more energy efficient, cooler running Core 2 Duo. Has it already been six months since the original MacBook was introduced? Then it must be time for an upgrade.
