About the AMD Radeon RX 6600 XT GPU

The Radeon RX 6600 XT is a desktop graphics card by AMD. It launched in Q3 2021 with a suggested retail price of $379. Its Navi 23 chip that powers the GPU uses the RDNA 2.0 architecture and is fabricated on the 7 nm process.

This GPU is paired with 8 GB of GDDR6 VRAM. Its 2,000 MHz memory clock and 128 bit interface gives it a bandwidth of 256 Gb/s. This impacts how much data it can store, and how fast it transfers the data to and from memory.

The RX 6600 XT is a dual slot graphics card, taking up 2 PCIe slots. It supports HDMI 2.1, DisplayPort 1.4a display ports. This desktop card has a TDP of 160 W. AMD recommends using a power supply of at least 450 W with this card. A power supply lower than this might result in system crashes and potentially damage your hardware.

The Radeon RX 6600 XT has the 41st highest 3DMark 11 Performance GPU score among the 540 benchmarked GPUs in our database. It achieves 37.21% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 39,051 score and $379 launch price (MSRP) gives it a performance per dollar of 103.04. This is the 14th best in value for the 3DMark 11 Performance GPU benchmark.
