Radeon RX 590 vs Radeon RX 6900 XT comparison

For gaming, the Radeon RX 6900 XT graphics card is better than the Radeon RX 590 in our tests.

The Radeon RX 6900 XT has a slightly higher core clock speed. This is the frequency at which the graphics core is running at. While not necessarily an indicator of overall performance, this metric can be useful when comparing two GPUs based on the same architecture. In addition, the Radeon RX 6900 XT also has a significantly higher boost clock speed. The boost clock speed is the frequency that the GPU core can reach if the temperature is low enough. The allows for higher performance in certain scenarios.

As stated by the manufacturer, the Radeon RX 6900 XT has significantly more memory with 16 GiB of memory compared to 8 GiB. If you're planning at playing games at high resolutions with high-quality textures, you will need a lot of memory.

In addition, the Radeon RX 590 has a significantly lower TDP at 175 W when compared to the Radeon RX 6900 XT at 300 W. Heat output doesn't match power consumption directly but, it's a good estimate.

In terms of raw gaming performance in our GPU benchmark, the Radeon RX 6900 XT is better than the Radeon RX 590.
