AMD Phenom II X4 975 Black Edition 3.6 GHz Socket AM3 Processor Review

AMD Phenom II X4 975 Black Edition 3.6 GHz Socket AM3 Processor Review - PCSTATS
Abstract: AMD's Phenom II X4 975 Black Edition is a quad-core, 3.6GHz socket AM3 chip with 6MB of L3 cache and 512KB of L2 cache per core. It's being released in tandem with the AMD Phenom II X4 840 CPU. Both processors are ideally suited to socket AM3 motherboards built around the recent AMD 890FX or 890GX chipsets.

CPU Calculation Benchmarks: wPrime2.0

wPrime 2.0 Source: WPrime

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.

Lower calculation times are better. wPrime is multi-threaded.

Wprime fills in where SuperPi leaves off by allowing PCSTATS to stress one core, or any number of cores up to the total amount in the processor. The most important result set to pay attention to is the final block of results for all threads.

With all four threads unleashed, the 3.6GHz AMD Phenom II X4 975 BE system out performs the Intel Core i5 750 with a time of 10.842. The 975BE is a hair slower than the eight-threaded Core i7 920 which posts a result of 9.766 seconds.

Next up, ScienceMark 2.3 and Cinebench R10...
