@mischievoustomato @Suiseiseki @Moon It's just a way nicer looking asm and sanely designed architecture compared to x86. I actually learned a bit of x86 asm around that point and it felt incredibly dirty to me. As for power efficiency concerns, that was down to economies of scale, Apple's partners fumbled hard with the G5 by essentially making their version of the Pentium 4 and Intel at the time had a really good contingency plan in the form of the Israeli-developed Pentium M and Core lineage. Eventually Intel repeated IBM's G5 mistake with Skylake, Apple decided to switch architectures *again*, and now they have ARM64 which if you squint really hard you could almost imagine is recent POWER.
