Fragz' verdict
The RTX 4070 Ti clearly outperforms the RTX 3080 Ti, leading by 17.3% in our overall GPU score. This performance edge is evident across our test suite, with the 4070 Ti delivering higher frame rates in Earth II Vulkan, Mission to Earth II DX12, and Earth II Landing DX12 Ultimate, driven by its significantly higher peak clock of 2910 MHz and a greater ALU index. However, gamers should note that the RTX 4070 Ti's data is currently based on a very thin sample of just one verified run, suggesting these numbers may shift with more measurements. Interestingly, the RTX 3080 Ti still holds a substantial lead in memory bandwidth, clocking in at 290 GB/s compared to the 4070 Ti's 138 GB/s, which could prove beneficial in certain bandwidth-heavy gaming workloads. Despite this, for raw tested performance, the RTX 4070 Ti secures a higher rank of 2 among all measured GPUs, while the RTX 3080 Ti sits at rank 4.

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
