Mac mini: 1.42GHz G4 vs. 1.66GHz Core Duo
Friday March 3, 2006 2:35 PM EST
Posted by: Brian

I put together a few benchmarks comparing a 1.4GHz G4 Mac mini to the new 1.66GHz Core Duo Mac mini. So far, I've been able to compare the two with Xbench, Geekbench, and Cinebench. I haven't had a chance to test our 1.5GHz Core Solo Mac mini yet, but based on these numbers, the new Intel-based Mac minis are looking good. On another note, I've received some mail asking about boot times for the new minis. I can report that the new 1.66GHz Core Duo Mac mini boots up in 28 seconds. My 1.42GHz G4 Mac mini takes around 46 seconds.
