GeForce 920MX vs GeForce GT 720M specs and performance

For gaming, the GeForce 920MX graphics card is better than the GeForce GT 720M in our tests.

Our database shows that the GeForce 920MX has a slightly 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 920MX 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 GeForce 920MX has a significantly lower TDP at 16 W when compared to the GeForce GT 720M at 33 W. Heat output doesn't match power consumption directly but, it's a good estimate.

In conclusion, all specs and GPU benchmarks considered, will recommend the GeForce 920MX over the GeForce GT 720M.
