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 i7-8700K. With six cores and 12 threads via HyperThreading, the CPU ensures even the most multi-threaded games won't be bottlenecked, and we've overclocked it to 5GHz as well with a base clock of 100MHz, a multiplier of 50 and a vcore of 1.3V, 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 H100i V2.

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 an OCZ Vector 180 960GB SSD, giving us plenty of space for game installs.

Our results come from a mix of built-in benchmarks and custom, manually played sections, depending on the game. All 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.
