AMD Ryzen 9 7900X Review

Super PI 2.1 WP

Super PI is a single-threaded benchmark that calculates pi to a specific number of digits. It uses the Gauss-Legendre algorithm and is a Windows port of a program used by Yasumasa Kanada in 1995 to compute pi to 232 digits

Available now on Super PI.

Starting with Super PI and here we see that the 7900X has managed to shave off just under two minutes compared to the 5900X. The 7900X does however, manage to pull ahead of the 12900K from Intel, while the higher core 5950X still manages to hold the top spot, albeit, only by a few seconds.

wPrime 2.11

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.

Available now on wPrime.

In wPrime, we see the 7900X storming ahead in the 32M calculation test, with a clear lead over the 5950X and 12900K, but at such a small calculation time, it doesn’t really give much to go off. The 1024M test however, paints a better picture, with the 7900X coming in as a clear winner at almost 9 seconds faster than the 5950X and considerably faster than the 12900k, though as we know, them pesky e-cores do skew this test somewhat.
