Well here are a few:

Not sure what happened there at the end. This is a dual core Cortex-A15
at somewhere between 1.0 and 1.5GHz (I have the frequency control driver
disabled so I can't actually tell what it is currently using).
Now for another system:
lennartsorensen-ppc
Using built-in specs.

That system is a 3.72GHz IBM p710 with a 6 core power7.
I am still waiting for the MPC8360e system to finish a run. It might be a while.
