Radeons RX 6600 XT are the most powerful graphics cards with the small AMD Navi 23 core. The Navi 22 in the RX 6700 XT is naturally better, but it still humbles the GeForce RTX 3060 with ease. However, in making this bold claim, it should be clarified that this dominance only works perfectly under certain circumstances – at lower resolutions without ray-tracing. This graphics card, in short, begs for high-speed monitor gamers with FHD resolutions.
