One could get the impression that POWER7 is very close wouldn't it have strong in-house competition from z196 ;-)

Yes, a fair comparison is not that trivial. Best performing ARM processors currently are based on cores implementing ARMv7-A ISA (i.e. ARM Cortex-A9, Qualcomm Scorpion, Marvell Sheeva PJ4) and it's clear that their performance is only a fraction of POWER7's (which is best performing PPC currently) performance. But for a fair comparison we'd have to take also wattage and price into account, calculating ratios like performance per wattage or performance per price.

Like the 4+ GHz quad-core Cortex-A9 based i.MX63 processor for 2011? ;-) I'm glad Freescale removed this nonsense roadmap from its website.

Don't tell that to Zylesea. He says he'd like to have a cheap product based on MPC5125 (yes, in the context we are speaking about here):
