3DMark measures graphical and CPU performance on PCs with a series of benchmarks that simulate demanding games. It includes tests such as Time Spy, Fire Strike, Port Royal, Night Raid, and Wild Life.
It allows you to compare your hardware with other systems, see frame rate estimates for popular games, and monitor temperature, GPU, and CPU usage during tests.
Additional features include stress tests to check stability, custom benchmark modes, and a Steam leaderboard for global comparison.
Minimum requirements on Windows are: dual-core 1.8 GHz processor, 4 GB RAM, DirectX 11 compatible graphics card, disk space for installation (only Time Spy requires ~2.9 GB).
