AMD Radeon RX 7800 XT 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.

AMD Radeon RX 7800 XT vs AMD Radeon RX 7900 XT: Which Should You Buy?
The AMD Radeon RX 7900 XT is 19% faster at 1440p ultra (125.9 fps against 105.8 fps). That is roughly one settings notch — enough to matter if you are chasing a specific refresh rate, not enough to rescue a bad price.
You pay a 36% premium for the AMD Radeon RX 7900 XT ($680 against $499) to get 19% more frames. The extra frames do not keep up with the extra cost — the AMD Radeon RX 7800 XT is the better value here.
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.
