Rasberry Pi vs old Dell, P4

A random smattering of Raspberry Pi vs an Old Dell P4 machine. Unfortunately I labeled the Rasberry Pi, Debian (it is running the debian image, at least).  You can view the full results at OpenBenchmarking.org.  Most people are not buying a Raspberry Pi for the performance :), but it is nice to know just how much slower the Pi is. The dell can pull between 70 - 120+ Watts, while the raspberry pi can pull 5.   Unfortunately, in performance per watt, I think the P4 still comes in first most of the time.  (The total test time on the P4 was less than an hour, the Pi I left overnight).  I didn't do much graphics testing, but the Raspberry Pi chip is physically better (not sure if it's being properly leveraged though).
