Mac Book - Apple claims significant performance boosts, up to 25 percent from the move to Core 2 Duo CPUs. In CNET Labs' Photoshop CS2 and iTunes encoding tests, we found that the new MacBook, with a 2.0GHz Core 2 Duo CPU and 1GB of RAM, performed admirably, coming in behind the 2.33GHz Core 2 Duo MacBook Pro model, but not by huge margins. That's even more impressive when you consider the MacBook Pro we tested had a whopping 3GB of RAM. As expected, both Core 2 Duo systems easily outclassed an older Core Duo MacBook Pro from earlier this year. We have updated our benchmarks recently, so we can't compare these scores directly against the last round of Core Duo MacBooks, but the new Core 2 Duo MacBook did show a 26 percent boost over the older Core Duo MacBook Pro, well in line with Apple's claims.
