Macworld’s initial benchmarks on Apple’s new iMac G5 show that the machine is 35 percent faster than the previous G4 model. “As you could probably guess, the new G5-equipped iMacs out-performed than their G4-powered predecessors,” writes James Galbraith. “Still, they weren’t as fast as the Power Mac models that come equipped with two G5 processors. Speedmark, our all-around system performance benchmark, showed that the 1.8 GHz iMac G5s were 35 percent faster than the 1.25GHz iMac G4. Some individual application tests, like rendering a scene using Maxon’s Cinema 4D, showed the new 1.8GHz iMac completing tasks in less than half the time it took the 1.25GHz G4 version.”
