> To be fair, modern x86 processors are RISC cores wrapped in an x86 decoder.
Look from the other side: the ISA is not so important; the technology has evolved to the point that the decoder is not a bottleneck anymore.

1) only if you don't care about the power used by the decoder, it sure has not helped Intel compete against ARM in embedded CPUs..
2) ISA still matter: from memory, going from x86 to x86-64 allowed a 10% improvement in benchmarks..
