Fragz' verdict
The Radeon RX 6600 XT takes the win in this comparison, leading the RTX 3060 by 7.5% in GPU score, though with only one verified run, its lead carries some uncertainty. This performance advantage is clear across the board, with the Radeon card achieving higher FPS in Earth II Vulkan (17.5 FPS vs 15.7 FPS), Mission to Earth II DX12 (22.5 FPS vs 20.5 FPS), and Earth II Landing DX12 Ultimate (20.4 FPS vs 19.7 FPS). Its significantly higher raw compute, with an ALU index of 238724 compared to the RTX 3060's 164979, is a major factor in this lead. However, the RTX 3060 comes with a more generous 12 GB of VRAM compared to the Radeon's 8 GB, plus a much higher memory bandwidth of 121 GB/s versus 42 GB/s, which could prove beneficial in games that are particularly memory-intensive.

What the numbers mean
The headline score is the part's best measured run, and the measurements under it come from that same run. It shows what the part has been proven to do — not what an average rig gets out of it. 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
