Fragz' verdict
The RTX 5080 clearly takes the win in this comparison, leading the RTX 4070 by a substantial 96.8% in overall GPU score, though our sample size of two verified runs for each card is thin. This performance gap is evident across all our GPU-focused tests, with the RTX 5080 delivering significantly higher frame rates, such as 73.6 FPS in Earth II Vulkan compared to the RTX 4070's 34.3 FPS. Gamers will notice a major upgrade in raw compute power, with the RTX 5080's ALU index of 800230 and its much wider memory bandwidth of 330 GB/s, alongside 16 GB of VRAM. For those prioritizing high refresh rates and maximum detail in modern titles, the RTX 5080 is the clear choice. However, if your budget is tighter and you're aiming for solid 1440p gaming without pushing the absolute limits, the RTX 4070, while clearly slower, still offers a capable experience.

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
