From downix:
I've even solicited help from some Linux kernel hackers to find the right benchmarks in order to demonstrate system bugs (which is Genesi's claims) as well as to back-up the claim that the A1 w/ G4 is as fast as a Pentium 4, which has been claimed in more than one thread here.
Why bother? I can't imagine there are many applications that run on both the P4 and G4... what will you compare, Linux-based games or something?
Otherwise you're asking a question with an already-known answer. Depending on the tasks, the G4 is as fast or faster than the P4 or even Athlon. Again, this is dependent on what the task is and how much optimization has gone into the software preforming the task.
http://bbs.xlr8yourmac.com/ubb/Forum26/HTML/000781.htmlHeh, I'm scoring loads of fun on that Mac forum today. Go ahead and test all you want, there's no point. Want me to save you some time? Here's the conclusion you'll get... "in some instances, the G4 can perform as fast or faster than some of the earlier, lower-clocked P4s. However, the G4 even at 1.42 GHz is no match for Intel's latest flagship CPU, the 3.06 GHz HT-enabled P4."
That's hardly worth the effort. Other people have done the work for you already. Are you afraid that the Amiga-specific motherboards will somehow cripple performance? Ok, that might be a valid concern. But a raw CPU comparison? Been there, done that. What people apparently have claimed in these forums IS true... depending on the test being run.
