HD 620 vs GeForce GTX 770 comparison

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

The GeForce GTX 770 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 770 also has a slightly 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 GeForce GTX 770 at 230 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 conclusion, all specs and GPU benchmarks considered, will recommend the GeForce GTX 770 over the HD 620.
