What reviewers say
Reviewers agree it is a fast 4K card with plenty of memory, clearly quicker than the RX 6950 XT, in a well-designed reference cooler. All of them found it hard to recommend at launch because the faster RX 7900 XTX cost only a little more; power draw is high, and ray tracing still trails NVIDIA.
