you can't even really compare the Athlon and the P4. and yet people try to compare RISC to CISC and use that as a basis for "why (insert brand x) sucks compared to Wintel, because we have 3GHz"
funny how back in the day, PPC whipped the holy living fuck out of x86 wihle at a lower clock... and everybody in the world was aware of it... but they've now conveniently forgotten that because now their stuff has big numbers and is "a couple of seconds faster" on running a filter that takes ten minutes to apply in Photoshop.
When you throw that many clock cycles at something... yeah, it'll be faster. But that doesn't make it *better*!
