In the G4 era, the marketing back then from Apple talked about the "Mhz Myth" and largely showcased stuff that was pretty much "Hey, this hand-tuned AltiVec code blows away this C++ -> x87 code on intel!" It's an interesting bit of history about how many very bright engineers had zero faith in intel being able pull off what they did with the P6 micro architecture: A superscalar, out-of-order x86 CPU that supported SMP on a power budget that, while high for the time (25 watts!), wasn't astronomical. That breakthrough ultimately became the foundation for Intel's Core micro architecture, which Apple later adopted in their first intel-based machines. If Apple had switched to Intel with the arrival of the Pentium, things could have been very different.
