NVIDIA GeForce RTX 3080 12 GB vs AMD Radeon RX 6900 XT
Side-by-side benchmark comparison, specs, pricing, and value analysis.
Benchmark Comparison
Gaming figures are average frames per second, measured by Tom's Hardware GPU hierarchy. Geometric mean of 15 games, ultra settings, no upscaling. Ray tracing figures are DXR-enabled at 1440p. A dash means the card was not tested at that resolution. Productivity and Steel Nomad are synthetic scores on their own scales and are not comparable to the fps columns.

Verdict
The NVIDIA GeForce RTX 3080 12 GB is the clear winner — it offers both better performance and better value.
NVIDIA GeForce RTX 3080 12 GB vs AMD Radeon RX 6900 XT: Which Should You Buy?
These two land on top of each other: 102.3 fps versus 102.1 fps at 1440p ultra, a 0% difference you will not notice in a game. The decision comes down to price, VRAM and power draw rather than speed.
Pricing settles it: the NVIDIA GeForce RTX 3080 12 GB is both faster and 25% cheaper at $799 versus $999. There is no scenario in this pairing where the AMD Radeon RX 6900 XT is the better buy at these prices.
Two things beyond raw speed: AMD Radeon RX 6900 XT carries 16GB against 12GB — the deciding factor at 1440p and above with ray tracing or texture packs, and the reason 12GB cards age badly; and the AMD Radeon RX 6900 XT draws 50W less (300W versus 350W), which can mean a smaller PSU and a quieter case; and the NVIDIA GeForce RTX 3080 12 GB is 2 years newer (2022 versus 2020), so it gets longer driver support and newer upscaling and frame generation features.
