It appears from your answer that a 2.4 GHz PPC would be > slower than a 2.4 GHZ Intel, with the same "universal" application ? Depends on how many cores and what you are doing. Here is a link to geekbench results. http://www.primatelabs.ca/blog/2008/06/mac-performance-june-2008/ or http://tinyurl.com/49lof3 Yes, any benchmark is an artificial test. Geekbench only tests the processor and memory. It does not test video or HD performance like xBench does. This makes it a slightly better test for core system performance, IMHO. It does take advantage of multiple processors and/or cores. For example the fastest G5 has 2 dual core processors at 2.5GHz (a total of 4 cores) and rates 3,290. The first Mac Pro had 2 dual core processors at 2.0 GHz (a total of 4 cores) and rates 3,855. For reference, the fastest G4 (MDD dual 1.42) rates 1,160 and the slowest G5 (the original crippled 1.6GHz) rates 1,008. If you are spending any kind of money on a system, I would look hard at an Intel Mac. Mainly, 10.6 and all future OSs will be intel only. If I would need to upgrade at work, I would be stuck at a G5, which are going for as little as $320 on ebay, since I still have a lot of classic apps that I run and intel Macs do not run classic apps natively. Although many people can get them to run via SheepShaver.
