I scarcely know where to start with this or with the rest of your comment.
PowerPC != ARM.
There are 64 bit ARM procs out there. G5s were 64 bit, but the Mac OS never leveraged that fact.
So let's see,
PowerPC (Performance Optimization With Enhanced RISC Performance Computing)
ARM (Advanced RISC Machine) and (Acorn RISC Machine)
Do you see any words that turn up in both in regards to cpu architecture? I don't know probably not. I mean the probability that the chips run on RISC is like 1 in 2 billion. ARM's currently in the market place are lower power/low watt 32bit RISC chips. Don't be so dense.
x86 is so different today from what it was in the 90s it's not even funny.
As orestes1984 noted, CISC is dead for all intents and purposes. RISC has been borrowed from heavily in both Intel and AMD procs since the turn of the century.
Please stop.
That's super its so different, ITS STILL x86. When Safari crashes on an Intel mac look at the crash log, you'll see x86 or references to it. And again to preserve ignorance Intel has never had any RISC processors outside there Itanium series that flopped because it was behind right out of the gate. Nothing was ever borrowed from Intel, it existed long before Intel. AMD had learned to adapt to multiple architectures, that's why they're in multiple super computers running cross platform today and Intel isn't.
It must be awesome to be so confident, speaking pure ************ like an uninformed child.
Stop.
