Fragz' verdict
The Radeon RX 7900 XTX takes a decisive lead in this comparison, outscoring the NVIDIA RTX PRO 4000 Blackwell by a massive 74.1% in overall GPU score. It's important to note that both cards have thin sample sizes, with only one or two verified runs respectively. The Radeon card consistently delivers higher frame rates across our GPU benchmarks, hitting 79.8 FPS in Earth II (Vulkan) and 101.6 FPS in Mission to Earth II (DX12), significantly outpacing the NVIDIA's 44.3 FPS and 56.2 FPS. This performance is supported by a much higher raw compute (ALU index of 803269 compared to 584939), despite the NVIDIA card having a higher memory bandwidth of 189 GB/s versus the Radeon's 122 GB/s. For gamers focused on raw rasterization power and higher FPS, the Radeon RX 7900 XTX is the clear choice based on these numbers, offering a smoother 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
