About the AMD Radeon RX 6900 XT GPU

The Radeon RX 6900 XT is a desktop graphics card by AMD. It launched in Q4 2020 with a suggested retail price of $999. Its Navi 21 chip that powers the GPU uses the RDNA 2.0 architecture and is fabricated on the 7 nm process.

This GPU is paired with 16 GB of GDDR6 VRAM. Its 2,000 MHz memory clock and 256 bit interface gives it a bandwidth of 512 Gb/s. This impacts how much data it can store, and how fast it transfers the data to and from memory.

The RX 6900 XT is a large graphics card, taking up 3 PCIe slots. It supports HDMI 2.1, DisplayPort 1.4a, USB Type-C display ports. This desktop card has a TDP of 300 W. AMD recommends using a power supply of at least 700 W with this card. A power supply lower than this might result in system crashes and potentially damage your hardware.

The Radeon RX 6900 XT has the 18th highest 3DMark 11 Performance GPU score among the 540 benchmarked GPUs in our database. It achieves 56.34% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 59,119 score and $999 launch price (MSRP) gives it a performance per dollar of 59.18. This is the 55th best in value for the 3DMark 11 Performance GPU benchmark.

About the AMD Radeon RX 7900 XT GPU

The Radeon RX 7900 XT is a desktop graphics card by AMD. It launched in Q4 2022 with a suggested retail price of $899. Its Navi 31 chip that powers the GPU uses the RDNA 3.0 architecture and is fabricated on the 5 nm process.

This GPU is paired with 20 GB of GDDR6 VRAM. Its 2,500 MHz memory clock and 320 bit interface gives it a bandwidth of 800 Gb/s. This impacts how much data it can store, and how fast it transfers the data to and from memory.

The RX 7900 XT is a dual slot graphics card, taking up 2 PCIe slots. It supports HDMI 2.1a, DisplayPort 2.1, USB Type-C display ports. This desktop card has a TDP of 300 W.
