NVIDIA RTX 4090 vs NVIDIA RTX 5080
How much faster one is than the other, and the resolution at which that difference turns into real frames. Reference: AMD Ryzen 9 7900, 32 GB of RAM.
The NVIDIA RTX 4090 is 16% faster than the NVIDIA RTX 5080 on paper, but paired with an AMD Ryzen 9 7900 it delivers no extra frames at all until 2560x1080 (Ultrawide 21:9). Below that resolution the processor caps both cards equally and you would be overpaying.
WHERE IT STARTS MATTERING
Real-world advantage of the NVIDIA RTX 4090 over the NVIDIA RTX 5080 at each resolution, paired with an AMD Ryzen 9 7900. At low resolution the processor caps both cards equally, so the faster one delivers nothing extra until the load moves onto the graphics card.

HOW THIS IS CALCULATED
The per-game frame rates are the ceiling each card sustains on its own at that resolution, with no processor limiting it. The resolution table does include the processor, because that is where you see whether the difference reaches you.
Native resolution, no upscaling and no frame generation. Measured model error · Methodology
