Power Consumption

Despite having significantly more power, the RTX 4080 Super managed to get away with using around 26% less power in our testing when compared to the RX 7900 XT. This brings the rather large power budget of the Radeon card to a much more manageable amount, which can lead to some savings in the lifespan of these cards.

Price And Value

Despite the performance improvement and the price cut that Nvidia has given to the RTX 4080 Super, it still stands as a worse value than the RX 7900 XT. The MSRP of the Radeon card has fallen significantly below its launch MSRP, which increases its value proposition further.

What We Recommend

RX 7900 XT: The RX 7900 XT has sustained its value since launch, offering commendable performance suitable for 1440p and even 4k gaming with some concessions on ray tracing and assistance from FSR. It’s an excellent choice for those seeking top-tier gaming without breaking the bank.

RTX 4080 Super: The RTX 4080 Super boasts high performance at a high price. It excels in all facets of modern gaming, including ray tracing. While the premium cost aligns with its top-notch capabilities, it’s a worthwhile investment if you prioritize cutting-edge features and exceptional gaming experiences.

Our discussion of the RTX 4080 Super vs RX 7900 XT concluded that the difference between the performance of these cards is just as important as the difference in price. The more well-rounded card also has a heftier price tag, whereas something like the RX 7900 XT has a few caveats, but it is still serviceable for high-end gaming.
