RTX 4080 SUPER vs RTX 3080
Short answer: which is best?
RTX 4080 SUPER is 59.9 % stronger than RTX 3080. RTX 4080 SUPER ranks #7 of 74 measured graphics cards at WhatFPS (14,460 GPU score in its best run — 1 rig, 2 verified runs). RTX 3080 ranks #17 of 74 measured graphics cards at WhatFPS (9,043 GPU score in its best run — best of 2 rigs, 2 verified runs). Each part is shown at its best run, picked from 4 verified WhatFPS runs — measured, not estimated, not self-reported.

Fragz' verdict
The RTX 4080 SUPER takes a decisive win here, leading the RTX 3080 by 55% in overall GPU score and ranking significantly higher at 5th place compared to the 3080's 17th. This performance gap is clear in our benchmarks, with the 4080 SUPER pushing 60.5 FPS in Earth II Vulkan, 76.6 FPS in Mission to Earth II DX12, and 63.3 FPS in Earth II Landing DX12 Ultimate, all substantially higher than the 3080's scores. Under the hood, the 4080 SUPER boasts a much higher peak clock at 2790 MHz, a superior ALU index, and more VRAM at 16 GB compared to the 3080's 1995 MHz, lower ALU index, and 10 GB, although the RTX 3080 does show higher memory bandwidth at 226 GB/s compared to the 4080 SUPER's 189 GB/s. For gamers, this means a significant jump in frame rates and a better experience in demanding titles, especially with the extra VRAM providing more headroom for future games. However, with only two verified runs for each card, our sample size is thin, so keep that in mind when weighing your options.

What the numbers mean
The headline score is the part's best measured run, and the measurements under it come from that same run. It shows what the part has been proven to do — not what an average rig gets out of it. The GPU score is the graphics card's own performance — that is what we rank on. GAMING is the whole rig's score in the best PC we measured the card in, and depends on processor, memory and storage. We show both and never mix them.
All numbers come from our benchmark suite: four hand-built 3D scenes written directly against the graphics APIs in Rust, the same load on every PC. The methodology is open at https://whatfps.com/metodik
