Otherwise, the new MacBooks have most of the same components as their older counterparts. The unit is slightly lighter at 5 pounds, as opposed to 5.1 pounds. There’s no embedded keypad, and the Apple symbol is now gone from the Command key. New media control keys are now located along the function key row, the same as in the new iMac keyboards. While there’s little to visually distinguish these MacBooks from their May 2007 counterparts, there has been a slight keyboard update. The MacBook’s new graphics processors don’t have dedicated video RAM, rather they share RAM with the main system memory, just like the previous models.

This is important because it provides the platform on which the rest of the improvements depend.įor example, you can now install up to 4GB of RAM, up from a recommended maximum of 2GB in the previous models (Apple recommends matched RAM pairs for the MacBooks for the optimal performance) the front side bus has been increased to 800MHz from 667MHz and the graphics chip has been updated to the Intel GMA X3100 with 144MB graphics allocation-the last generation had the Intel GMA 950 with 64MB. The new models have been upgraded from the Calistoga chipset architecture to the Santa Rosa architecture. The new MacBooks also feature the newest chip architecture, a faster front side bus, an updated graphics processor, and increased RAM capacity-twice that recommended for the previous models. The new high- and mid-range models now clock 2.2GHz, which slightly tops the previous generation’s 2.16GHz speed. Let’s start with speed: there’s a modest difference if you just look at the numbers. The newest glossy-screened MacBooks look nearly identical to their six-month-old siblings, but a number of significant under-the-hood improvements have added new zip to this generation with no increase in price.
Apple has once again updated its popular consumer laptop.
