HD 620 vs Radeon RX 550 comparison

According to the hardwareDB Benchmark, the Radeon RX 550 GPU is faster than the HD 620 in gaming.

Our database shows that the Radeon RX 550 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 550 also has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

In addition, the HD 620 has a significantly lower TDP at 15 W when compared to the Radeon RX 550 at 50 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

In terms of raw gaming performance in our GPU benchmark, the Radeon RX 550 is better than the HD 620.
