Er, it wasn't a matter of Intel "acquiring the technology" to do "more
work with less clock speed". The Pentium 4 "Willamette" architecture
was designed from the beginning to do less work per clock cycle so
that the clock rate could be scaled up better. But higher clock rates
do not work well in conserving power as you need in a laptop. That's
why the Pentium M's clock rate is so much slower doing a similar
amount of work.
Intel had this "technology" in it's previous Pentium III
architecture. What Intel has figured out though is that faster clock
rates are no longer the best way to market their chips. Centrino was
the first step away from that, as they emphasized features over
performance. The new numbering scheme is something similar.
