GeForce RTX 4090 vs Radeon RX 7900 XTX comparison

In our benchmarks, the Radeon RX 7900 XTX beats the GeForce RTX 4090 in gaming performance.

Our database shows that the GeForce RTX 4090 has a slightly higher core clock speed. The core clock speed (or base speed) is the frequency at which the GPU core runs. This metric makes sense when comparing GPUs of a similar architecture or generation. In addition, the GeForce RTX 4090 also has a slightly higher boost clock speed. The boost clock speed is the frequency that the GPU core can reach if the temperature is low enough. The allows for higher performance in certain scenarios.

As stated by the manufacturer, they both have the same amount of memory at 24 GiB. If you're planning at playing games at high resolutions with high-quality textures, you will need a lot of memory.

In addition, the Radeon RX 7900 XTX has a slightly lower TDP at 355 W when compared to the GeForce RTX 4090 at 450 W. Heat output doesn't match power consumption directly but, it's a good estimate.

According to the results of the hardwareDB benchmark utility, the Radeon RX 7900 XTX is faster than the GeForce RTX 4090.
