Maximum Power
Of all benchmarks we looked at, Prime95 torture test is the one that qualifies to bring out the best (or worst) of any CPU with respect to power consumption and thermal load. Needless to say that in the case of multiple CPUs, multiple instances of the benchmark need to run in parallel in order to pull all resources.
Prime95
There is a difference between assigning the second Prime95 load to the second logical unit of the same CPU and assigning it to an independent core.
With each logical CPU assigned to another instance of Prime95 (we ran a total of four individual parallel instances at the same time), the CPU utilization increases by another 100%/number of logical units, in this case 25%.
Maximum power at cool and "slightly" overheating CPUs. Once again, the numbers for the P4 840 remain rather constant, there is simply not much headroom for additional heat in this case. Keep in mind that this is isolated CPU power and not system power.
