Of course, now Apple has famously switched to Intel processors, and they offer nothing but praise of Intel CPUs. Gee, isn't it odd how they used to deride the Pentium and praise the PowerPC?
As the saying goes... "Where you stand depends on where you sit."
See:

and read:
So wow, dude, so like, the PowerPC totally rocks over Intel CPUs? Mark my words, these claims that Apple espouses are still on the Apple.com site even after Apple embraced Intel.Fastest Bus in the West
The G5 features a scalable design that enables it to run at clock speeds up to 2.7GHz. But all the megahertz in the world wouldn’t mean squat if the G5 were stuck talking to the rest of the machine at the 167MHz bus speed of the Power Mac G4. That’s why each G5 features two unidirectional 32-bit data paths: one traveling into the processor and one traveling from the processor, unlike previous designs. Its frontside bus works at speeds up to 1.35GHz for an astounding 10.8GBps of total bandwidth. That makes it over 280MHz faster than even the latest Intel 925XE chipset, which sputters out at 1066MHz.
Now that Apple has a new religion, you'd expect that they would've purged, as the Soviets would have, any history of the old religion. Not true! Apple.com still offers pages proclaiming the superiority of ... the now-discredited PowerPC chip!
My guess is that Apple will eventually assign someone to the task of purging Apple.com of all evidence that Apple ever claimed that the PowerPC chip was ever superior to Intel's chips.
But even when they do, Apple can always live with this screen shot, from Apple.com, in June 2006, ridiculing Intel CPUs compared to their previous engine. Click to see full-size image.
