"The Transaction Processing Performance Council (TPC) today
announced its newest specification, TPC-Energy, which measures the
energy usage of a server to gauge not only transactions per second
but transactions per watt as well.
"TPC benchmarks are a standard measure of performance used by
every major server vendor to boast about the speed of their
hardware. The top performers list is constantly changing as vendors
release new servers.
"But the one thing those lists didn't discuss was how much
energy was burned to achieve those results. Two servers may come
within a whisker of each other in terms of performance numbers, but
if one vendor needed five times the hardware and consumed five
times as much power to get similar results as the other, a buyer
might want to know that detail.
"Plus, it's needed to keep the vendors honest. Vendors can be a
little sneaky some times by listing the power draw of a bare bones
system that goes up exponentially once you add all the pieces you
need to actually do the job."
