When reviewing a gaming laptop or desktop, we run preset tests using several games, including Far Cry 5, Metro: Exodus and others, along with standard benchmarks like 3DMark, which is designed to test a computer's 3D graphic rendering capabilities.

For this list, we're ranking the laptops in descending order of 3DMark Fire Strike Ultra scores, but the real-world game scores (presented as the number of frames of animation per second the laptop can render) match very closely. Note that these scores are specifically for the exact configurations of each laptop we tested, and almost all can be configured with a wide range of options.
