Fragz' verdict
This comparison is a landslide victory for the RTX 5090, which leads the Radeon 680M by a staggering 3157.4% in GPU score, securing the top rank out of 66 cards. The performance difference is clear across the board, with the RTX 5090 delivering 132.8 FPS in Earth II (Vulkan), 171.4 FPS in Mission to Earth II (DX12), and 113 FPS in Earth II Landing (DX12 Ultimate), while the Radeon 680M struggles with 4.1, 4.3, and 3.9 FPS respectively. This immense gap is driven by the RTX 5090's vastly superior raw compute, featuring an ALU index of 1020560, 660 GB/s of memory bandwidth, 31 GB of VRAM, and a peak clock of 3112 MHz, compared to the Radeon 680M's ALU index of 36353, 8 GB/s bandwidth, and 2 GB of VRAM. It is worth noting that the Radeon 680M's data comes from only one verified run, so its exact performance might vary slightly. For serious gaming, the RTX 5090 is the obvious choice, with the Radeon 680M only being suitable for extremely light tasks where gaming is not a consideration.

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
