GeForce GTX 980 vs HD 620 benchmarks

For gaming, the GeForce GTX 980 graphics card is better than the HD 620 in our tests.

In our comparison, the GeForce GTX 980 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 GeForce GTX 980 also has a slightly 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 GeForce GTX 980 at 165 W. TDP (Thermal Design Power) measures total heat output from the chip.

In terms of raw gaming performance in our GPU benchmark, the GeForce GTX 980 is better than the HD 620.
