I see where the conversation is going.
What I meant was relative to an ARM chip.

If rebuilt using digital equivalent of quantum computer,
which requires another 5% extra silicon, then computing
power would increase x10 to x100 with 5% extra consumption.
So the power saving would be astronomical, or equivalently
the throughput is much greater, but since
a lot of software would have to be rewritten, the trade off in benefit
is not easy to work out until the software world catches up.

Regardless of Intel or ARM, the throughput is limited by
page cycle times of DDR which hasn't improved since the 80's and stuck
at 10MHz. The ARM wins because the quiescent drain is much lower despite
both CPUs having the same DDR limit.
Digital version of quantum computers will get over that,
but normal software can't work on such computers.
