How the comparison works
Both cards are read from the same reference table as the FPS calculator: a typical average frame rate for each graphics chip in each game at 1080p, 1440p and 4K, at the settings shown beside the game title. These are estimates, not measurements of your PC.
The comparison assumes a processor fast enough not to limit either card. With a slower processor the gap narrows, most of all at 1080p, because both cards end up waiting for the processor. The bottleneck calculator shows where that happens.
The headline percentages compare the average across every game, so the fast competitive games weigh more than the slow, demanding ones. The game-by-game table shows where the gap opens up and where it closes.
Cards in the same performance class in our data show as level. That does not make them the same card. Price, memory, power draw, noise and features all differ, and this table does not model them.
