What reviewers say
Reviewers agree it is very fast in games without ray tracing, often ahead of the pricier RTX 4080, and a big step up from the RX 6950 XT, in a compact reference design. The common criticisms are ray tracing well behind NVIDIA and high power draw; PC Gamer's two reference samples both ran with excessive hotspot temperatures, and KitGuru heard coil whine.
