A phenomenon known as the $300,000,000 PC.
Frank DiGilio's Mainframe Mythbusting presentation cites the Wall Street
Journal as saying distributed server farms can generate up to 3800 watts
per square foot! A z9 EC generates only 312 watts per square foot. (Less
than 10%.)
I heard an opinion from some PC bigot that this is the proof that Intel
platform offers "denser computing power". More watts mean more CPUs,
channels, etc. <vbg>

I do not support the opinion above.
</explanation for those who need it>
Seriously speaking, nowadays is experience denser packaging of servers,
disks, etc. and some devices (like CPUs) need more power - all of that
causes more watts/m2 (or sq. ft) More power also means more cooling (and
again more power). This is an issue for "infrastructure personnel",
because usuallay old server rooms are not prepared for such change and
changing it without outages for production systems is really hard work.
