Fragz' verdict
The Radeon RX 7900 XTX clearly takes the win over the RTX 4070 SUPER, leading by a massive 79% in GPU score. This performance gap is evident across the board, with the Radeon card delivering significantly higher framerates: 79.8 FPS in Earth II (Vulkan) compared to 44.2 FPS, 101.6 FPS in Mission to Earth II (DX12) versus 55.6 FPS, and 89.5 FPS in Earth II Landing (DX12 Ultimate) against 51 FPS for the RTX 4070 SUPER. Backing this up, the Radeon RX 7900 XTX boasts a much higher raw compute with an ALU index of 803269 compared to 511416 and double the VRAM at 24 GB, though it's important to note the Radeon's data comes from a thinner sample of only two verified runs. For gamers, this means a substantial difference in high-resolution and high-refresh-rate gameplay, with the Radeon offering a smoother and more robust experience in demanding titles. However, with a solid GPU score and 10 verified runs, plus a higher memory bandwidth of 150 GB/s compared to 122 GB/s, the RTX 4070 SUPER still presents a strong option for those looking for capable performance in the upper mid-range.

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
