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.
  • Riva TNT has the most memory: 8 MB or 16 MB depending on board against 4 MB on standard RIVA 128 boards.
  • Riva TNT has the most memory bandwidth: About 1.76 GB/s against 1.6 GB/s.

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.
