Calculation Tests
SuperPi
Super PI is a computer program that calculates pi to a specified number of digits after the decimal point—up to a maximum of 32 million. It uses Gauss–Legendre algorithm and is a Windows port of the program used by Yasumasa Kanada in 1995 to compute pi to 232 digits.
wPrime
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 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. Then it confirms that n(k)2=k to ensure the calculation was correct. It is repeated for all numbers from 1 to the requested maximum.
Please note that items marked with an asterisk are measured with 4 threads. Those not marked are tested with as many threads as the CPU has available. We will retest anything that is possible and update with better-comparable numbers.
