AMD RX 6800 XT vs AMD RX 6600
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 AMD RX 6800 XT is 97% faster than the AMD RX 6600 on paper, but paired with an AMD Ryzen 9 7900 it delivers no extra frames at all until 1280x720 (HD 16:9). Below that resolution the processor caps both cards equally and you would be overpaying.
WHERE IT STARTS MATTERING
Real-world advantage of the AMD RX 6800 XT over the AMD RX 6600 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
