Fragz' verdict
The RTX 5080 is the clear winner here, leading the Radeon 680M by a massive 1832.7% in GPU score. This huge gap is evident across all our tests, with the RTX 5080 delivering significantly higher frame rates, such as 74.1 FPS in Earth II Vulkan compared to the Radeon 680M's 4.1 FPS, and 88 FPS in Mission to Earth II DX12 versus 4.3 FPS. The RTX 5080 also boasts vastly superior raw compute with an ALU index of 714811 against 36353, much higher memory bandwidth at 331 GB/s versus 8 GB/s, and a substantial 16 GB of VRAM compared to 2 GB. For gamers, this means the RTX 5080 is in a completely different performance class, offering a premium gaming experience while the Radeon 680M struggles even at low settings. While the Radeon 680M's single verified run suggests a thin sample, its low performance numbers clearly place it as an entry-level or integrated solution, not a competitor for high-end gaming.

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
