Radeon Vega 11 vs Radeon RX 6400 comparison

For gaming, the Radeon RX 6400 graphics card is better than the Radeon Vega 11 in our tests.

Our database shows that the Radeon RX 6400 has a significantly higher core clock speed. The core clock speed (or base speed) is the frequency at which the GPU core runs. This metric makes sense when comparing GPUs of a similar architecture or generation. 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 Vega 11 has a significantly lower TDP at 15 W when compared to the Radeon RX 6400 at 53 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 6400 is better than the Radeon Vega 11.
