Radeon RX 7800 XT vs GeForce RTX 4090 D benchmarks

In our benchmarks, the GeForce RTX 4090 D beats the Radeon RX 7800 XT in gaming performance.

In our comparison, the GeForce RTX 4090 D has a slightly higher core clock speed. This is the frequency at which the graphics core is running at. While not necessarily an indicator of overall performance, this metric can be useful when comparing two GPUs based on the same architecture. In addition, the GeForce RTX 4090 D also has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

As stated by the manufacturer, the GeForce RTX 4090 D has significantly more memory with 24 GiB of memory compared to 16 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 7800 XT has a significantly lower TDP at 263 W when compared to the GeForce RTX 4090 D at 425 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

In conclusion, all specs and GPU benchmarks considered, will recommend the GeForce RTX 4090 D over the Radeon RX 7800 XT.
