Radeon RX 6400 vs Radeon RX 560 XT specs and performance

For gaming, the Radeon RX 6400 graphics card is better than the Radeon RX 560 XT in our tests.

In our comparison, the Radeon RX 6400 has a significantly 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 6400 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.

In addition, the Radeon RX 6400 has a significantly lower TDP at 53 W when compared to the Radeon RX 560 XT at 150 W. TDP (Thermal Design Power) measures total heat output from the chip.

In terms of raw gaming performance in our GPU benchmark, the Radeon RX 6400 is better than the Radeon RX 560 XT.
