GeForce GTX 660 vs GeForce GT 720M specs and performance

According to the hardwareDB Benchmark, the GeForce GTX 660 GPU is faster than the GeForce GT 720M in gaming.

The GeForce GTX 660 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 GTX 660 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 GT 720M has a significantly lower TDP at 33 W when compared to the GeForce GTX 660 at 140 W. Heat output doesn't match power consumption directly but, it's a good estimate.

According to the results of the hardwareDB benchmark utility, the GeForce GTX 660 is faster than the GeForce GT 720M.
