NVIDIA's GeForce RTX 5080 -  Expected Performance
The NVIDIA GeForce RTX 5080 will replace the RTX 4080 and recent rumors suggest that it will offer 10% better performance than the RTX 4090. The RTX 5080 might be better at just Ray Tracing than RTX 4090 as going by the specifications, the RTX 4090 seems to have an edge over the 5080.

Nonetheless, several theories could prove both scenarios and we will need some concrete data to say whether the RTX 5080 is superior to RTX 4090 or not. Compared to the RTX 4080, it's almost guaranteed that the 5080 will be much faster due to an upgrade in specs, which means we can see 60+ fps at 4K resolution in most titles. We should also remember that the RTX 4080 was 20-25% faster than the RTX 3090 and we can expect similar if not better gains from the RTX 5080.

The NVIDIA GeForce RTX 4080 & 4080 SUPER have been delivering some solid performance in modern titles in both rasterization and ray tracing and we can expect the RTX 5080 to continue its domination at higher resolution, particularly at 4K since it brings a higher memory bandwidth.
