AMD Radeon RX 6900 XT vs AMD Radeon RX 7900 XTX
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.

AMD Radeon RX 6900 XT vs AMD Radeon RX 7900 XTX: Which Should You Buy?
This is not a close race. The AMD Radeon RX 7900 XTX delivers 135.3 fps at 1440p ultra to the AMD Radeon RX 6900 XT's 102.1 fps, a 33% gap. Only pick the slower card if it is dramatically cheaper or you need it for a lower resolution.
Pricing settles it: the AMD Radeon RX 7900 XTX is both faster and 4% cheaper at $959 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 7900 XTX carries 24GB 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 6900 XT draws 55W less (300W versus 355W), which can mean a smaller PSU and a quieter case; and the AMD Radeon RX 7900 XTX is 2 years newer (2022 versus 2020), so it gets longer driver support and newer upscaling and frame generation features.
