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.
So starting with Super PI and straight away, we do see a decent amount of time shaved off the 7900X showing the impact that faster memory has on the 7900X. With the 7600X and the Intel Alder Lake CPUs, the gain in time wasn’t as significant, potentially pointing to a stronger memory controller on the 7900X.
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.
Moving onto wPrime and looking at 32M and we actually see very little movement in this test, though to get a better picture, we have to look at the 1024M test, but even here, we see a real mixed bag of results. Firstly with the 7900X, we see a 5% increase in the time to calculate when using faster memory, while the 7600X sees a slight drop in calculation time and Intel results are skewed due to the E cores being enabled.
