Key Differences

  • No game was measured on every one of these cards on one shared test system, so there is no speed comparison to make.
  • RTX 5080 has the most memory bandwidth: 960 GB/s against 716.8 GB/s.
  • RTX 4080 draws the least power: 320 W against 360 W.

Muted cells indicate unavailable, not applicable, or not directly comparable specifications.

Frame rates compare runs of the same game at the same quality preset on one test system. DLAA counts as native resolution, because it applies anti-aliasing at full render resolution rather than upscaling; DLSS and FSR upscaling are never counted as native. Where a capture named ray tracing without a readable on or off value, it is read as on.

Measured game results

Gaming benchmarks

Reviewed FPS from games these cards were measured on under one shared test system and resolution. Every game is compared against itself, so each result is a like-for-like pair. These results are separate from theoretical compute specifications.

No shared approved gaming benchmark yet

The selected GPUs do not currently share reviewed measurements from the same game, test system and resolution. No result was estimated or filled in.
