SuperPi is a single threaded benchmark that simply calculates digits out to a specific number of places and times how long it takes.  For this, we used the XS mod 1.5 version, since this is most common among overclockers. 

Times are in seconds, and lower numbers are better.                                

As we have noted in previous reviews, SuperPi is generally an Intel dominated benchmark, and being a single-threaded benchmark, the amount of cores present is generally meaningless.  The 2.7% clock speed advantage over the 955 provides a 5.8% reduction in time, which translates to a pretty good value.  Of course, the overclocked 955 and 965 are truly neck and neck. 

wPrime 2.00:

According to the wPrime website, wprime does the following:

"wPrime uses 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. "

wPrime is essentially calculating prime numbers and then timing how long it takes.  For this, we are using version 2.00.  Just like SuperPi, times are in seconds, and thus, lower scores are better.

While SuperPi is an Intel dominated test, wPrime tends to favor the Deneb architecture.  This means the 965 had the best showing amongst all stock processors, and was within a very tight margin with the overclocked x3360 and X4 955. 

For the 1024M , the 965 really began to flex its muscles, taking down every other stock CPU by a wider margin than the 32M test, and firmly taking the lead over the CPUs when overclocked.
