DF on ray tracing - RTX 3080 is twice as efficient as RX 6800 XT

Digital Foundry specialists have prepared a detailed analysis of the ray tracing capabilities of the Radeon RX 6800 XT and GeForce RTX 3080. Eurogamer’s technical department compared two graphics cards from NVIDIA and AMD.

  • To measure the capabilities, the frame rendering time in milliseconds was chosen, not the frame rate. The first method made it possible to more accurately estimate the obtained values
  • The process of rendering a frame with tracing enabled consists of four steps: scene preparation, ray tracing, shading and noise reduction.
  • Shading in DIRT 5 and Metro: Exodus rendered almost the same load on video cards, the AMD video card showed 13% worse performance, but this is not critical

  • In more complex scenarios, the RX 6800 XT lagged more
  • For example, the RTX 3080 handles global illumination and reflections 2-3 times better.
  • When a scene needs to track a large number of rays or take into account rough surfaces with high scattering coefficient, the RTX blocks in the NVIDIA graphics card do their job more efficiently
  • At the same time, in the most difficult tasks like tracing global illumination with two reflections in Quake RX 6800 XT, it again catches up with RTX 3080

Similar testing was conducted by PC Gamer in December last year. The results were the same – the RTX 3080 is up to twice as efficient in some ray tracing tasks.
