Our testing methods
Most of the numbers you'll see on the following pages were captured with OCAT, a software utility that uses data from the Event Timers for Windows API to tell us when critical events happen in the graphics pipeline. We run each test run at least three times and take the median of those runs where applicable to arrive at a final result.

As ever, we did our best to deliver clean benchmark numbers. Our test systems were configured like so:

Processor Core i7-7700K
Motherboard Gigabyte Aorus GA-Z270X-Gaming 8
Chipset Intel Z270
Memory size 16GB (2 DIMMs)
Memory type G.Skill Trident Z
(run at DDR4-3200)
Memory timings 15-15-15-35 2T
Hard drive Samsung 960 EVO 500GB
Kingston HyperX 480GB
2x Corsair Neutron XT 480GB
Power supply Seasonic Prime Platinum 1000W
OS Windows 10 Pro with Creators Update

Thanks to Intel, Corsair, Kingston, and Gigabyte for helping to outfit our test rigs with some of the finest hardware available. AMD, Nvidia, and EVGA supplied the graphics cards for testing, as well. Behold our Gigabyte Aorus Z270X-Gaming 8 motherboard in all its glory:

Unless otherwise specified, image quality settings for the graphics cards were left at the control panel defaults. Vertical refresh sync (vsync) was disabled for all tests. We tested each graphics card at a resolution of 2560x1440 and 144 Hz, unless otherwise noted.

The tests and methods we employ are generally publicly available and reproducible. If you have questions about our methods, hit our forums to talk with us about them.
