Thanks to Asus, Cooler Master, Corsair, Intel, and Samsung for providing the hardware used in our test systems. And thanks to the motherboard makers for providing those.
We used the following versions of our test applications:
- 7-Zip 9.20 64-bit
- TrueCrypt 7.1a
- Chrome 34.0.1847.131
- x264 r2431
- DiRT Showdown demo
- CrystalDiskMark 3.0.3b
- FRAPS 3.5.99
- RightMark Audio Analyzer 6.2.5
- Cinebench R15
- Unigine Valley 1.0
Some further notes on our test methods:
- All testing was conducted with motherboard power-saving options enabled. These features can sometimes lead to slightly slower performance, particularly in peripheral tests that don't cause the CPU to kick into high gear. We'd rather get a sense of motherboard performance with real-world configurations, though; we're not as interested in comparing contrived setups with popular features disabled.
- DiRT Showdown was tested with ultra detail settings, 4X MSAA, and a 1920x1200 display resolution. We used Fraps to log a 60-second snippet of gameplay from the demo's first race. To offset the fact that our gameplay sequence can't be repeated exactly, we ran this test five times on each system.
- Power consumption was measured at the wall socket for the complete system, sans monitor and speakers, using a Watts Up Pro power meter. The full-load test combined Cinebench's multithreaded CPU rendering test with the Unigine Valley DirectX 11 demo running in a 1280x720 window. We reported the peak power consumption during the Cinebench run. Our idle measurement represents the low over a five-minute period sitting at the Windows desktop.
- The Force GT 120GB SSD was used as the system drive for all tests. The Samsung 850 Series 512GB was connected as secondary storage to test Serial ATA and USB performance, the latter through a USAP-compatible Thermaltake BlacX 5G docking station. The Samsung SSD was secure-erased before each test that involved it. The Corsair drive was also wiped before we loaded our system image.
- Ethernet performance was tested using a remote rig based on an Asus P8P67 Deluxe motherboard with an Intel 82579 Gigabit Ethernet controller. A single Cat 6 Ethernet cable connected that system to each motherboard.
- Analog audio signal quality was tested using RMAA's "loopback" test, which pipes front-channel output through the board's line input. We tested while the system was loaded with Cinebench's multithreaded rendering test, the Unigine Valley benchmark, and a CrystalDiskMark 4KB random I/O test running on the Samsung SSD attached via USB 3.0.
The tests and methods we employed are publicly available and reproducible. All tests except power consumption were run at least three times. Unless otherwise indicated, we reported the median result for each test. If you have questions about our methods, hit our forums to talk with us about them.
