Fragz' verdict
The RTX 5080 takes a decisive lead in this comparison, outperforming the NVIDIA RTX PRO 4000 Blackwell by a significant 53.7% in overall GPU score, though both cards have very thin sample sizes with only one or two verified runs. This performance gap is clear across our GPU benchmarks, with the RTX 5080 hitting 73.6 FPS in Earth II (Vulkan) compared to 44.3 FPS, and 91.7 FPS in Mission to Earth II (DX12) versus 56.2 FPS. Its higher peak clock of 3000 MHz, superior raw compute with an ALU index of 800230, and much greater memory bandwidth at 330 GB/s contribute to a smoother, faster gaming experience. While the NVIDIA RTX PRO 4000 Blackwell does offer more VRAM at 24 GB compared to the RTX 5080's 16 GB, its lower performance means it's not the primary choice for raw gaming power based on these numbers.

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
