RX 7900 XT Vs RTX 3080: Which One Would We Recommend?

RX 7900 XT: If you want to purchase a GPU with a better performance per dollar value, the 7900 XT is better. Additionally, it might be the better option if you are concerned with thermal efficiency due to its lower temperatures.

RTX 3080: If ray-tracing and upscaling technology are your primary requirements, then the RTX 3080 might be the better option. Until AMD releases its FSR 3.0 technology, DLSS will remain the better option.

In conclusion, which GPU you should purchase depends solely on your requirements. For that reason, in-depth research is often required before purchasing.

Frequently Asked Questions

Does the RX 7900 XT require a new power supply?

It would help if you had an 800W power supply to use the RX 7900 XT without problems. You might want to upgrade if you have a PSU weaker than 800W.

Does the RTX 3080 support DLSS 3.0?

Because DLSS works on machine learning, no RTX 3000 series GPU supports DLSS 3.0, including the RTX 3080.

Can I fit an RX 7900 XT in a Small Form Factor case?

While the possibility of fitting a Radeon RX 7900 XT in an SFF case exists, it depends on the exact measurements of the chassis. For reference, the RX 7900 XT has a length of 276mm, a width of 135mm, and a height of 51mm.
