From http://en.wikipedia.org/wiki/Z196_CPU
IBM has CISC z/Architecture CPU with a new superscalar, out-of-order pipeline with 5.2Ghz speeds. Like any modern X86, this IBM Z-Arch CISC CPU includes CISC-to-RISC hybrid design.
Z196 was announced on July 22, 2010.
Interesting, the previous Z11 was a pure CISC chip, this is just mostly CISC.
It can only be a matter of time before it gets merged with POWER though.
It looks like IBM is going to fight Intel/AMD X86-64 with it's own 1970s 64bit CISC ISA CPU.
No, the Z series is for mainframes only. It's exotic and highly expensive hardware and they make vast sums of money from it.
My point, the RISC migration adventure was a waste of time.
But you're saying the opposite - everyone has gone RISC internally.
Anyway, in the embedded market RISC is king and it's much, much bigger than desktop.
