NVIDIA GeForce RTX 3090 Ti 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.

Verdict
The AMD Radeon RX 7900 XTX is the clear winner — it offers both better performance and better value.
NVIDIA GeForce RTX 3090 Ti vs AMD Radeon RX 7900 XTX: Which Should You Buy?
The AMD Radeon RX 7900 XTX is 20% faster at 1440p ultra (135.3 fps against 112.7 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.
Pricing settles it: the AMD Radeon RX 7900 XTX is both faster and 108% cheaper at $959 versus $1,999. There is no scenario in this pairing where the NVIDIA GeForce RTX 3090 Ti is the better buy at these prices.
Two things beyond raw speed: the AMD Radeon RX 7900 XTX draws 95W less (355W versus 450W), which can mean a smaller PSU and a quieter case.
