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