Prices And Electricity Costs

While there has been no official news of a drop in production, Nvidia’s RTX 3080 has been in short supply for a while. Thus, prices have been quite high, and the cheapest RTX 3080 is available for $869 while writing this. On the other hand, at least one RX 7800 XT variant can be found for its launch price of $499. That totals to a 74.1% difference in the lowest prices of the two cards. 

Also, the RTX 3080, with its higher power consumption, can also deliver a bigger hit on electricity bills.

Which GPU Has Better Value?

To cap things off, let’s determine the better value graphics card. The RX 7800 XT outperformed the RTX 3080 by 4.4% and 2.9% in my 1440P and 4K benchmarks, respectively. And, at the moment, it’s about 74.1% cheaper as of October 2023.

So, the AMD Radeon RX 7800 XT has 78.5% and 77% better value regarding 1440P and 4K gaming, respectively. Of course, we also must remember that the RX 7800 XT is less power-consuming.

RTX 3080 Vs RX 7800 XT: Which GPU Would I Recommend?

After thoroughly comparing the two graphics cards in specifications, performances, and prices, I found the RX 7800 XT to be the better overall card. Not only does it have much better value, but it also has an impressive 16GB of VRAM, which is plenty for your 1440P and 4K gaming needs. So, I would recommend it over the GeForce RTX 3080

As for the GeForce RTX 3080, age isn’t by its side. Not only is it over three years old (while writing this), it’s not even available for its launch price tag. If you really want an Nvidia card, the RTX 4000 series (particularly the RTX 4070) is a better option, as its performance is about the same at a fraction of the price.
