Church of BSD: Intel CPU efficiency Chart.

This data was collected from Wikipedia and the Intel Web site.

If we assume 1 CPU clock tick is of equal value on all Intel Processors then we can work out total speed as the clock speed times the number of cores.

In actually is much more complicated.

Graph above last updated in 2005 and doesn't include data beyond the original P4 processors.

The above chart attempts to work out the amount of processing per clock tick on a single core.

What was interesting is the 1/3 drop in the amount of work done per cycle on the highest end P4 CPU's.

The Chart below is sorted from Worst to best. I included the older 3.8 GHz P4 and P4M for comparison. These are 2 to worst entries at the top of the table.
