HD 620 vs Radeon RX 6400 specs and performance

For gaming, the Radeon RX 6400 graphics card is better than the HD 620 in our tests.

Our database shows that 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. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

In addition, the HD 620 has a significantly lower TDP at 15 W when compared to the Radeon RX 6400 at 53 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

According to the results of the hardwareDB benchmark utility, the Radeon RX 6400 is faster than the HD 620.
