someone's points need to be taken seriously. he has
very extensive knowledge of uarchs, and seemingly
unlimited access to obscure intel literatures.

cortex-a9 is doing some *non-trivial* tricks to reduce
power consumption, while at the same time have to
deal with crazy stuff like handling interrupt efficiently
to support drm features like Trustzone. if arm
decided to go after the pc market, they would be facing
an expensive validation effort, and have to document
the uarch and memory model. that's very different
from the market they've been serving.

besides, when a9 silicon is out, people are going to
subject it to some *real* bechmarks. guess we have to
wait and see if a9 pans out.
