I would be very interested to see some ARM results in that chart in the future; at the moment, all the RISCs there are pretty dismal.
Not so long ago I remember doing some calculations on the SPEC results, normalising them to a single thread and clock frequency to determine the per-cycle efficiency of various CPUs, and x86 came out at least a factor of 2-3x ahead of the rest.
