For a custom PC builder there’s nothing more satisfying than finishing up your build so you can put it to the test. Sure you can open up an application and perform certain tasks to give you an idea of how your new build is performing, but you can also use specific programs that are designed specifically to benchmark.
One of these applications is actually quite simple. SuperPi calculates Pi to a specific number of digits and then displays the time it took to calculate the answer for each iteration. You can also determine the accuracy of the calculation which can also help determine stability of the system, this is perfect for overclocking.
It’s important to note that SuperPi is intended to test single threaded performance, if you’re looking to test multi-threaded performance you can utilize wPrime.
wPrime uses a recursive call of Newton’s method for estimating functions, with f(x)=x2-k, where k is the number we’re square rooting, 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.
