Fragz' verdict
The RTX 4080 absolutely dominates this comparison, leading the Radeon 680M by a massive 1582.5% in GPU score, placing it fourth overall among all GPUs we've tested. This huge gap is evident across all our GPU benchmarks, with the RTX 4080 hitting 62.9 FPS in Earth II (Vulkan) and 77.9 FPS in Mission to Earth II (DX12), while the Radeon 680M manages only 4.1 FPS and 4.3 FPS in the same tests. The RTX 4080's vastly superior raw compute with an ALU index of 539839, 195 GB/s of memory bandwidth, 16 GB of VRAM, and a 2895 MHz peak clock crushes the Radeon 680M's 36353 ALU index, 8 GB/s bandwidth, and 2 GB VRAM, meaning the RTX 4080 is built for high-end gaming. Based on these results, and with the Radeon 680M only having one verified run, it's clear this card, despite supporting features like ray tracing and mesh shaders, is simply not in the same league for any meaningful gaming performance.

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
