Radeon RX 7900 XTX vs GeForce RTX 4090
Radeon RX 7900 XTX
GeForce RTX 4090
Radeon RX 7900 XTX and GeForce RTX 4090 perform within a few percent of each other for gaming. Both sit in the same class, and our framerate data has each of them limited by the processor rather than the card itself, so neither holds a decisive lead. Choose on price, power draw and the features you actually use.
Radeon RX 7900 XTX vs GeForce RTX 4090 at a glance
Each axis is scored against the better of the two, so the outer edge is always the stronger part on that measure, not an absolute scale.

Which one should you buy?
Choose the Radeon RX 7900 XTX if
- Lower power draw (355 W)
- Cheaper at launch ($999)
Choose the GeForce RTX 4090 if
Nothing in our data favours this one. Pick it only if it is cheaper today.
How many FPS do the Radeon RX 7900 XTX and GeForce RTX 4090 get?
Estimated framerates with both parts measured against the same reference processor (a AMD Ryzen 7 9800X3D), so the graphics card is the only thing changing. Figures are ranges, not exact numbers. Measured at 1440p because at 1080p even a fast processor caps both cards and the columns come back identical.

Which is better value?
At launch pricing, the Radeon RX 7900 XTX delivers more benchmark performance per dollar, by about 29%. Street prices move, so check current cost before deciding: a 29% value gap disappears quickly on discount.
Will the GeForce RTX 4090 bottleneck your build?
These figures hold one component constant. Your own build decides the answer: a faster graphics card buys nothing if the processor is already the limit.
How we compare graphics cards
Benchmark scores come from PassMark, 3DMark, Geekbench and Cinebench. Each of those suites is read from a single source across every part we compare, so a percentage gap here is a difference between the two chips rather than between two testers. Framerates come from our own model, built from measured GPU baselines and processor ceilings, and it declines to produce a number for hardware it does not cover rather than estimating one.
