HD 620 vs Radeon RX 6600 comparison

According to the hardwareDB Benchmark, the Radeon RX 6600 GPU is faster than the HD 620 in gaming.

In our comparison, the Radeon RX 6600 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 6600 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 HD 620 has a significantly lower TDP at 15 W when compared to the Radeon RX 6600 at 132 W. Heat output doesn't match power consumption directly but, it's a good estimate.

According to the results of the hardwareDB benchmark utility, the Radeon RX 6600 is faster than the HD 620.
