Fragz' verdict
The RTX 3080 Ti clearly outperforms the RTX 4070, securing a 14.3% lead in overall GPU score, though we must note the RTX 4070's performance is based on a single verified run. The 3080 Ti consistently delivered higher frame rates, hitting 42.4 FPS in Earth II Vulkan against the 4070's 35.5 FPS, and reaching 53.7 FPS in Mission to Earth II DX12 compared to 45.8 FPS from its counterpart. This superior performance stems from its higher raw compute, reflected in an ALU index of 497242, and a significantly wider memory pipeline, boasting 290 GB/s bandwidth versus the RTX 4070's 137 GB/s, which means more data can be accessed faster for smoother gaming. While both cards feature 12 GB of VRAM and support advanced rendering like ray tracing, the RTX 3080 Ti currently stands as the stronger choice for raw power, though the 4070's higher peak clock of 2790 MHz could make it an interesting alternative if other factors come into play.

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
