The Radeon RX 6650 XT replaces the RX 6600 XT in AMD’s lineup. That one beats the GeForce RTX 3060 in performance under certain circumstances, but always only narrowly. Now, after the GPU’s frequency and memory bandwidth increase, Radeon’s dominance is clear, and yet efficiency is still on AMD’s side. The non-reference Sapphire Nitro+ design is also super-quiet – the cooler is now quite a bit more robust.
