Processor comparison?

Question

Iron

There is a load of 6% on the Intel Xenon E3-1220 processor (8M Cache, 3.10 GHz).
Is it possible to somehow find out or estimate how much % the same calculations will take on a weaker Intel Celeron Processor 1.70 GHz, 128K Cache, 400 MHz
Or is it impossible to make such an estimate?

Answer 1

cpuboss.com - here you can compare processors by characteristics and performance tests. It goes without saying that the load - it can be different and must be compared on real hardware.
