"Superior" is a matter of what you want to do with it. If, for instance, you want to put your "superior" chip in a laptop, you better get a battery the size of a cinderblock and a heatshield for the family jewels ;)
I don't what you're thinking, but a Mac with a PPC chip has far superior battery life than an Intel based chip. For instance, I have an Inspiron 8100 with 850mhz CPU and an iBook with an 800mhz G4. Inspiron lasts maybe 2 hours while the iBook lasts 7 hours. And the iBook is half weight of the Inspiron. Now who's superior?
What?! You don't wear Asbestos underwear???
