Quadro P400 vs Radeon RX 6400 comparison

In our benchmarks, the Radeon RX 6400 beats the Quadro P400 in gaming performance.

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.

Next up, in terms of GPU memory, the Radeon RX 6400 has significantly more memory with 4 GiB of memory compared to 2 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 Quadro P400 has a significantly lower TDP at 30 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 Quadro P400.
