RPi Performance

Wondering how the Raspberry Pi compares to other computers? I just checked that using nbench-byte.

rasp1My Raspberry PI arrived a few days ago. I’m pretty happy and I love that little thing. It’s however, somewhat slow and it’s use as Desktop is questionable (at least until x11 gets accelerated properly). However. I read some statements that the RPi’s performance is comparable to the performance of a Pentium 3. Due to that and because I’m pretty interested in how the RPi compares to other systems I checked that using nbench-byte. Below the results.

Speed Idle temp. Max. temp. Score1
700 MHz 0 overvolt 45,4°C 47,6°C 2,47
800 MHz 0 overvolt 46,0°C 49,8°C 2,85
900 MHz 2 overvolt 46,0°C 51,3°C 3,22
950 MHz 6 overvolt 46,5°C 54,0°C 3,47
1000 MHz 6 overvolt 47,0°C 56,2°C 3,66

1) The scores were calculated using the same formula used here. If you compare the above scores with the results there, you’ll notice that the RPi is worse than a Pentium 3 with identical MHz (not much though). EVEN if you overclock it to 1 GHz. Lot better than the VIA with 800 MHz as you can see.

You can get the current speed of your RPi using:

cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq

The usual command (cat /proc/cpuinfo) won’t show the current speed. You can get the temperature of your RPi using:

cat /sys/class/thermal/thermal_zone0/temp
