Fragz' verdict
The RTX 4080 SUPER is the undeniable victor here, outperforming the RTX 3080 Ti by a significant 43.7% in overall GPU score. This translates directly to higher frame rates across our tests, hitting 79.2 FPS in Mission to Earth II DX12 compared to the RTX 3080 Ti's 53.7 FPS, backed by its superior 2775 MHz peak clock and a larger 16 GB of VRAM for demanding titles. While the RTX 4080 SUPER's performance is impressive, it's important to note that its data comes from a single verified run, making the sample thin. The RTX 3080 Ti, with its strong 290 GB/s memory bandwidth and an ALU index of 497242, still offers solid gaming performance and could be a smart choice if found at a better value.

What the numbers mean
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
