Fragz' verdict
The RTX 5090 is the undisputed winner in this comparison, leading the RTX 4070 by a substantial 230.8% in GPU score, though we should note the RTX 4070’s results are based on a thin sample of only 2 verified runs. This immense performance difference translates directly to gaming, with the RTX 5090 hitting 132.8 FPS in Earth II Vulkan compared to the RTX 4070's 34.3 FPS, and similar leads in Mission to Earth II DX12 and Earth II Landing DX12 Ultimate. The RTX 5090 backs this up with a significantly higher peak clock of 3112 MHz, a massive raw compute ALU index of 1020560, and a huge 660 GB/s of memory bandwidth paired with 31 GB of VRAM. For gamers seeking the absolute best frame rates and future-proofing for the most demanding titles, the RTX 5090 is the clear top-tier choice. However, if your gaming demands are more modest and you don't require peak performance at the highest settings, the RTX 4070 still offers a capable experience in its own class.

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
