Other than that, the people don't pay attention unless it's a hindrance. Which PPC was but Apple thought it was being different back in the 90s for whatever reason.
Not saying the Intel leap didn't make sense at the time but there was nothing wrong with PPC. The PPC601 and PPC604 absolutely SPANKED the early Pentiums. The later G3's were faster than the Pentium II. The G4 was faster than the Pentium III for a long time until the P-III finally got a severe clock speed advantage for a couple years. The G5 obliterated the Pentium IV performance-wise, especially in floating point.
The biggest issue is the PPC manufacturers (Freescale, Motorola, IBM) couldn't/wouldn't dump the R&D dollars necessary to improve power efficiency and they always lagged behind in clock speed except for the initial major CPU releases. Intel is simply "good enough" and fast. That does not make it a great architecture. Hell, even back in the 386/486 days the Motorola 68030 and 68040-based Macs were often faster at lower clock speeds. The PowerPC was a damn good architecture and still is.
I've seen several desktop workstation architectures come and go..... VAX, Alpha, m68k, m88k, PPC, SPARC (arguably not quite dead yet), PA-RISC, etc.... All of them had real measurable advantages over x86. But x86 is very common, thus lots of R&D dollars available to propel it to "good enough" status and let people run legacy x86 crap. That doesn't mean x86 is always better and people should ignore anything else. Personally, I like choice! Especially when the other choices are very innovative and compete on merit rather than existing market presence.
