A simple benchmark

Fri Jul 13, 2012 8:49 pm

I ran this command to do a very simple benchmark (from a console, not within X)

Code: Select all

time echo "scale=2000;4*a(1) | bc -l
I wanted to test some of the overclocking options mentioned in Dom's post (see the link in the RPi main page about Raspbian).

So ... in Puppy (SAP Alpha 3)

With the over-voltage overclock, (1Ghz) the "real" time was:
15.774 secs.

With the "safe" overclock, (arm - 850, sdram - 500, gpu - 250), I got:
22.339s

With no overclocking:
22.464s

As a quick comparison, I ran the test on my Arch installation (this is using the same "safe" overclock) and got:
20.489s

Just out of interest, I ran this on my laptop, which is a Pentium 3 with 256mb of RAM (so similar to the sort of machine to which Eben has claimed the Pi might have similar performance). It is running Racy Puppy.
The time was:
17.259s

Anyone else tried any benchmarking recently?
