Is the most powerful G4 the 1.67Ghz from the Powerbook G4?
The fastest G4 is the 7448 dualcore cpu with a frequency of 2Ghz.
I would prefer to see some real tests instead of "Meaningless Information Processor Speed".
Show me some ARM machine I can buy that is faster than a Powermac G5 QuadCore from 7 years ago. If there are no faster ARM machines available in the mass market then ARM is 7 years behind PPC.
Those complains about cpus usually come from ex-amiga users or people who doesn't use amiga at all. My powerbook G4 at 1.67Ghz runs MorphOS nicely and MorphOS would fly on a 2.5-2.7Ghz G5.
If MorphOS had to switch architecture in 6 years I would always choose x86, there are millions of computers available and all them are way faster than anything ARM that exists.
