CPU PPD ESTIMATES BY LOGICAL PROCESSORS USED BETA

The following data for the Intel(R) Xeon(R) CPU E5-2666 v3 @ 2.90GHz is estmated based on the average PPD per each logical CPU processor mulitplied by various counts of those logical processors.

PPD data for CPUs is presented this way as folders can optimize their setup by folding on any number of the CPUs available logical processors on a project work unit.

How many logical processors a folder should use for best results is suggested based on the number of GPUs they may also be folding on to allow CPU bandwidth for GPU folding.

The max logical processors a CPU has available should only be used on a system that is dedicated solely to CPU folding with very little other overhead.
