AMD Radeon RX 6800 vs AMD Radeon RX 7900 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 AMD Radeon RX 7900 XT is the clear winner — it offers both better performance and better value.
AMD Radeon RX 6800 vs AMD Radeon RX 7900 XT: Which Should You Buy?
This is not a close race. The AMD Radeon RX 7900 XT delivers 125.9 fps at 1440p ultra to the AMD Radeon RX 6800's 89.2 fps, a 41% gap. Only pick the slower card if it is dramatically cheaper or you need it for a lower resolution.
You pay a 17% premium for the AMD Radeon RX 7900 XT ($680 against $579) to get 41% more frames. The extra performance more than covers the extra cost.
Two things beyond raw speed: AMD Radeon RX 7900 XT carries 20GB against 16GB — the deciding factor at 1440p and above with ray tracing or texture packs, and the reason 16GB cards age badly; and the AMD Radeon RX 6800 draws 50W less (250W versus 300W), which can mean a smaller PSU and a quieter case; and the AMD Radeon RX 7900 XT is 2 years newer (2022 versus 2020), so it gets longer driver support and newer upscaling and frame generation features.
