AMD Phenom II X6 1075T 6-Core Processor Performance ReviewFri, Dec 03, 2010 - 12:00 AM
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.
Benchmark Results: The AMD Phenom II X6 1075T was 23 seconds or 7.7% faster calculating 1024m than it’s predecessor the Phenom II X6 1055T.
