What reviewers say
Reviewers agree it is strong value for 1440p gaming, with 16 GB of memory and speed slightly above the RTX 4070 in games without ray tracing. The common criticisms are that it is barely faster than the RX 6800 XT, trails NVIDIA in ray tracing and is less efficient. PC Gamer and KitGuru found the reference card quiet, Tom's Hardware did not.
