HD 620 vs UHD 770 benchmarks

For gaming, the UHD 770 graphics card is better than the HD 620 in our tests.

By comparing the spec sheets, both the HD 620 and the UHD 770 have the same base clock speed. Despite this, the UHD 770 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, both the HD 620 and the UHD 770 have an identical TDP. Heat output doesn't match power consumption directly but, it's a good estimate.

According to the results of the hardwareDB benchmark utility, the UHD 770 is faster than the HD 620.
