AMD Radeon RX 6900 XT

Released in 2020, the Radeon RX 6900 XT is a GPU from AMD. According to our GPU Benchmark, this GPU is an incredible card for gaming with a score of 137%.

The Radeon RX 6900 XT has 16 GiB of GDDR6 memory, with a total memory bandwidth of 500 GB/s. The memory bus has a width of 256 bits. More memory is beneficial when gaming at high resolutions as the memory needs to store the frame buffer and all the game textures. If you run out of memory, you will experience poor performance as the GPU needs to swap data in and out of the memory as it is used.

In terms of clock speed, the Radeon RX 6900 XT GPU core runs at a frequency of 1825 MHz and if power and temperature permits, it can boost up to 2250 MHz. The clock runs at a speed called the clock speed. It dictates the number of updates per second that the GPU can process. Overclocking a chip, which means increasing the clock speed will improve the performance. However, thermals and power efficiency may be diminished.

As for rendering API support, the Radeon RX 6900 XT supports up to DirectX 12. In addition, in cross-platform titles, OpenGL 4.6 features are supported. Newer APIs are usually more efficient, allowing for better performance in games and better graphical effects.

Power and thermals for the AMD Radeon RX 6900 XT are a TDP (Thermal Design Power) of 300 watts. This measures the amount of heat the GPU produces when running at 100%. This isn't a measure of power consumption, but it's a good estimate.
