I don't remember the earlier ARM designs, but
it was my impression that DEC's StrongARM was the one that made really large strides
in low power (especially power per MHz of clock speed). Interestingly enough, StrongARM
was one of the few (and the first?) independent designs; it used the ARM architecture
specification but not the actual logic design as others did.
Hmm. That wasn't my impression at the time, no.

So at least in the marketing to the Acorn user community, no, power
draw wasn't even mentioned. It never came up. The original ARMs were
low-power, and so was StrongARM.
Remember that the marketing in question was DEC marketing, well known for its utter
ineptitude. That had its origin in Ken Olsen's belief that marketing wasn't
really needed (and, for that matter, that sales people didn't need to be paid
commission).
I very definitely remember discussions at the time about the unprecedented power/bandwidth
value delivered by the SA110. "One mW per MIPS" is one phrase that I remember
from that time.
