"The only way you can get low power out of an x86 is to cut the performance. VIA C3 is a good example of this."
Actually the Via C3 CPU has so poor performance, mainly because Via is a much smaller company than Intel, AMD and IBM, specialised in mobo chipsets. They most obviously don't have the funds to hire a legion of electronics engineering experts like Intel or AMD and therefore the design of their cpu's is monolithic and competely anoptimized. I read somewhere that the Via C3's design ressembles mainly to that of intel 486! :-?
