AMD PHENOM II X4 955 3.2GHz + GA-MA790FXT-UD5P

So for our tests, we are using the a Cooler Master Real Power Pro 850W power supply, Windows XP SP3, and 2x 2GB of XMS1600 DDR3 memory from Corsair:

Now, we move on to the all-important test results. Complete, updated tables can be found in the Summary Page. Note that the info below is the latest at the time of this writing, and only selected rows are included:

As we can see here, the 955 holds its own very well, even surpassing the 8x Xeon cores in the DVD Shrink and WinRAR tests! Amazing. But where floating-point calculations are used such as in Prime95 and SuperPi, even the two-core Core2Duo T9300 mobile CPU performs faster than the quad-core 955.

In the Cinebench tests, the 955 did relatively well, just a little below half of the 8-core Xeons. Note that the X5482 are also 3.2GHz CPUs. However, the 955 did manage to exceed the Xeons in a couple of the 3D Mark CPU tests. Not bad at all!

In the Everest tests, we were very pleasantly surprised to see how well the X4 955 scored. Most if not all the scores were either at the top or within the top 5 of each set. Only Xeons bested the X4 955 in a few tests. However in the FPU tests, we see the X4 955 struggle a bit against the Core2Duo-based architecture.

One very interesting bit about power management on the Phenom II X4 955: It throttles down each core to 800MHz, that's even lower than the 1GHz minimum of the Athlon 64!

In the end, the AMD Phenom II X4 955 Black Edition is a CPU worth every penny. With such tremendously strong performance at such an affordable cost, its actually a no-brainer. It can execute most multimedia tasks faster than a some Xeons too! If AMD can build on this architecture, maybe a Phenom III could be an i7 killa. Bravo!
