Test Setup

Our GPU test rig uses Intel's Z370 platform. Specifically, we use the Asus ROG Maximus X Hero paired with an Intel Core i9-9900K. With eight cores and 16 threads via Hyper-Threading, the CPU ensures even the most multi-threaded games won't be bottlenecked, and we've overclocked it to 4.9GHz as well with a base clock of 100MHz, a multiplier of 49, and a vcore of 1.315V, further alleviating CPU bottlenecks. The CPU is paired with 32GB (4 x 8GB) of Corsair Vengeance RGB DDR4 clocked at 3,200MHz and cooled by a Corsair Hydro Series H115i Pro RGB.

The rig is powered by the Corsair AX1500i, which has enough wattage and eight-pin PCIe power connectors to deal with any multi-GPU set-up we care to throw at it. It's all housed inside a Corsair Carbide Series Air 740, which is spacious enough for any card. The final component is a Corsair Force Series MP510 960GB PCIe 3.0 x4 M.2 SSD, giving us plenty of space for game installs and keeping load times down.

Our results come from a mix of built-in benchmarks and custom, manually played sections, depending on the game. All game benchmarks are repeated at least three times to ensure consistency. We test at 1,920 x 1,080 (1080p), 2,560 x 1,440 (1440p), and 3,840 x 2,160 (4K), though some resolutions are excluded if they are deemed inappropriate for a certain card. The operating system is an up-to-date copy of Windows 10 64-bit.

As well as the average frame rate, we report the 99th percentile frame rate that is a better representation of the "minimum" frame rate in terms of experience than the single slowest frame of the entire benchmark. Obtaining this figure involves using software (currently OCAT - the Open Capture and Analytics Tool) to record the render time of every single frame in a benchmark, meaning poor performance has nowhere to hide. Such software typically gives you a 99th percentile frame time in milliseconds. Dividing 1,000 by this figure converts it into a frame rate measurement.
