SuperPi:
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 singlethreaded
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)=x^{2}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.
