go to

http://www.apple.com/powermac/specs.html

to see a comparison between g4(risc) P4(CISC)

also a dual 1Ghz G4 runs at about 15 Gigaflops

I can't find the flops specs for the p4 chip so i can't really do a direct conparison - but ask your selve why doesn't intel have the information on there site easily excessable like apple, maybe because they don't want people to actually compare the two?? this also true for AMD although they do compare against intel they don't compare against apple?

Also choasforages you said that modern X86 processors convert X86 instructions into rops or risc ops wouldn't this slow down the processor because it has to convert the instructions before it can execute them?

Also if the Xbox and gamecube can only do 8 and 10 gigaflops why would you get one the new Nvidia geforce 4 Ti is supossed to be able to do 1.23 trillion operations per second i am lead to beleive that a Gigaflop is 1 billion operations per second, this would mean that the Geforce 4 can do 1.23 TeraFlops????? (1230 Gigaflops) (i could be wrong correct me if i am wrong  

choasforages:
umm, instructions per second are different than megaflops. megaflops are like floating point arithmatic. like those funny fractions. and translating x86 instructions into riscops is the reason that "fast" x86 processors exist. for more info try www.transmeta.com i don't know if they have any info but they tout the translation as the best part of there chips
