Erlang & performance / watt

I'm intrigued by this:
"If there are enough threads (hardware and software), one should never
have to speculate. The eight CPU cores were a throwback to early RISC
designs: single-issue, in-order, nonspeculative."
So, it looks as if Intel was going down a cul-de-sac with speculative,
out-of-order, hyperthreaded, overheating billion transistor etc... CPUs,
and that the RISC paradigm is destined for a resurgence. I have a
fondness for simple, orthogonal CPUs.
... And that a multicore Erlang CPU might find a market yet? (ducking to
avoid the flames, not just those from Buncefield nearby:
