That is an interesting article, thanks.  It is nice to see what a more
recent effort in this area looks like.

The most telling part of the article, to me, is on page 5, where the
Valve developer notes:

    To be honest, we're more concerned with main memory bandwidth than
    the type of core interconnect.

This CPU really isn't the limiting factor any longer, now that a cache
miss can cost you half a thousand cycles.  The rest of the system,
especially bus bandwidth, is now the real key point to optimize for at a
hardware level.


The one thing they didn't include, and I can't say I am surprised, are
details on how much development effort with their coders -- some of the
best in the world -- was required to get things working.
