Here we will run some targeted benchmark tests to gauge the raw performance/calculation speed of the CPUs.
wPrime is a leading multithreaded benchmark for x86 processors that tests your processor performance by calculating square roots with a recursive call of Newton’s method for estimating functions, with f(x)=x2-k, where k is the number we’re sqrting, until Sgn(f(x)/f'(x)) does not equal that of the previous iteration, starting with an estimation of k/2. It then uses an iterative calling of the estimation method a set amount of times to increase the accuracy of the results. It then confirms that n(k)2=k to ensure the calculation was correct. It repeats this for all numbers from 1 to the requested maximum.
WPrime we see that to no surprise the 3900X with eight extra threads easily outpaces the 9900K even with its higher clockspeed. The big surprise here was the even lower clocked low power 3700X which also readily beat the 9900K in the long test while the shorter test I found a strange bug where preparing the threads causes a delay with the new Ryzen platform, or it may even be a hiccup from the Bios bugs still being worked out.
