Fragz' verdict
The Radeon RX 7900 XTX is the clear winner, outperforming the UHD Graphics 770 by an astonishing 10775.9% in GPU score, though both cards have a thin sample of verified runs. The Radeon RX 7900 XTX delivers vastly superior performance across all our tests, hitting 79.8 FPS in Earth II (Vulkan) and 101.6 FPS in Mission to Earth II (DX12), compared to 0.7 FPS and 1.8 FPS respectively for the UHD Graphics 770. This massive gap is supported by its significantly higher raw compute with an ALU index of 803269, 122 GB/s memory bandwidth, and 24 GB of VRAM, while the UHD Graphics 770 has an ALU index of 20381, 7 GB/s bandwidth, and 0 GB of VRAM. Furthermore, the Radeon RX 7900 XTX supports ray tracing and mesh shaders, capabilities the UHD Graphics 770 lacks, providing more advanced in-game effects without directly impacting the GPU score. For gamers, the Radeon RX 7900 XTX is undoubtedly the choice for any serious gaming, as the UHD Graphics 770, ranking last among all GPUs, is only suitable for basic display output or extremely light desktop use where a dedicated graphics card is not an option.

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
