Performance - WPrime
The tool that overclockers like so much to determine performance and stability. In this test, we max out the number of threads corresponding to the processor and calculate 1024M of prime. This software is a computer program that calculates a set number of square roots using Newton's method for estimating functions, verifying the results by squaring them, then comparing them with the original numbers.
Wprime still shows a top score for the 3990X, however, the 1024M tasks are finished so fast that re-spawning all 128 threads all of the time creates a lot of system and IO overhead, that in fact is slowing down the results IMHO.
