Test your processor performance with wPrime

wPrime is a leading multi-threaded benchmark for x86 processors that tests your processor performance by calculating square roots with a recursive call of Newton's method for estimating functions.



The calculation is done 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.

The aim was to make a perfectly threaded benchmark, such that it would consistently use 100% of the CPU while in use. This is achieved by using CPUz to detect the CPU count and use exactly that many processing threads to avoid any performance losses due to multiple threads running on any single physical thread.

wPrime retrieves most hardware information thanks to CPUz. It retrieves CPU information such as clock speed, code name, cache size, voltage, etc. It retrieves the motherboard model and the amount, speed and timings of your memory.
