Benchmark scores in other reviews are only comparable when this exact same configuration is used.

  • All games and cards are tested with the drivers listed above—no performance results were recycled between test systems. Only this exact system with exactly the same configuration is used.
  • All graphics cards are tested using the same game version.
  • All games are set to their highest quality setting unless indicated otherwise.
  • AA and AF are applied via in-game settings, not via the driver's control panel.
  • Before starting measurements, we heat up the card for each test to ensure a steady state is tested. This ensures that the card won't boost to unrealistically high clocks for only a few seconds until it heats up, as that doesn't represent prolonged gameplay.
Each game is tested at these screen resolutions:
  • 1920x1080: Most popular monitor resolution.
  • 2560x1440: Intermediary resolution between Full HD and 4K, with reasonable performance requirements.
  • 3840x2160: 4K Ultra HD resolution, available on the latest high-end monitors.
