Test notes
Please note that we've included a "Phenom ES 2.6GHz" processor in the results on the following pages. This is an engineering sample chip clocked at 2.6GHz with a 2GHz north bridge that AMD supplied to us back when the Phenom first launched. No real Phenom product is yet shipping at this speed, but we've included it for comparison's sake, nonetheless.
Also, we have included performance results for a couple of very high-end systems, including a dual Xeon X5365 system and a Skulltrail dual Core 2 Extreme QX9775 rig. With eight cores and price tags in the many thousands of dollars, such systems aren't direct competitors for any Phenom AMD currently offers. If their presence annoys you, hold up two fingers to the screen to block out the bars representing them while reading the performance graphs.
Our testing methods
As ever, we did our best to deliver clean benchmark numbers. Tests were run at least three times, and the results were averaged.
Our test systems were configured like so:

Please note that testing was conducted in two stages. Non-gaming apps and Supreme Commander were tested with Vista patches KB940105 and KB929777 (nForce systems only) and ForceWare 163.11 drivers. The other games were tested with the additional Vista patches KB938194 and KB938979 and ForceWare 163.71 drivers.
Thanks to Corsair for providing us with memory for our testing. Their products and support are far and away superior to generic, no-name memory.
Our single-socket test systems were powered by OCZ GameXStream 700W power supply units. The dual-socket systems were powered by PC Power & Cooling Turbo-Cool 1KW-SR power supplies. Thanks to OCZ for providing these units for our use in testing.
Also, the folks at NCIXUS.com hooked us up with a nice deal on the WD Caviar SE16 drives used in our test rigs. NCIX now sells to U.S. customers, so check them out.
The test systems' Windows desktops were set at 1280x1024 in 32-bit color at an 85Hz screen refresh rate. Vertical refresh sync (vsync) was disabled.
We used the following versions of our test applications:
The tests and methods we employ are usually publicly available and reproducible. If you have questions about our methods, hit our forums to talk with us about them.
