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).

  1. It would be interesting to have compared the beaglebaord as well. The ARM7 is a bit more powerful than the ARM6 in the rπ, and the power consumption is closer to 2W.

    That said any of these cheap ARM board will probably win a “whats the cheapest, smallest, quietest, most energy efficient way computer that can do X”

    1. Indeed. I wasn’t sure of a good way to take that into account :/… Now that I think of it, doing extracting, etc on a removable usb stick might do it.

  2. Thanks for testing, Bryan! I’ve been on the fence about ordering a Raspberry Pi, and knowing it’s relative speed really helps me make that decision.

    What clock speed does the P4 claim it has? (Check cpu MHz from /proc/cpuinfo.) Wikipedia says P4s varied from 1.3 GHz to 3.8 GHz, and I’m hoping yours isn’t from the low end of that range.


  3. Do you have any MP4 file playback benchmarks in there? You’ll be surprised!

    Now I’m going back to my OpenElec XBMC build for the Raspberry Pi and my Hobbit HD trailer which I’m using to show the REAL power of the RasPi.

  4. Are you using the official Debian image without floating point support or the Raspbian image with floating point support?

  5. A useful indicator, thanks – it sounds to me like the P4 is better if you’re expecting to run at any sort of load, but the RPI is better if you just want a server with constant availability and the lowest possible power consumption
