Think SecretDetails of the MacBook update are less known, although there is a strong possibility that the laptop will also take advantage of Santa Rosa, which can be configured with Core 2 Duo processors at speeds of 1.8GHz, 2.0GHz, 2.2GHz, and 2.4GHz. The faster speeds will almost certainly be reserved for the MacBook Pro. More significant for MacBook owners is the faster Intel GMA 3000 graphics processor that Apple will be able to use, delivering improved graphics performance.
