GeForce GTX 660M vs GeForce 930MX benchmarks

In our benchmarks, the GeForce GTX 660M beats the GeForce 930MX in gaming performance.

Our database shows that the GeForce 930MX 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 930MX 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 930MX has a significantly lower TDP at 17 W when compared to the GeForce GTX 660M at 50 W. TDP (Thermal Design Power) measures total heat output from the chip.

According to the results of the hardwareDB benchmark utility, the GeForce GTX 660M is faster than the GeForce 930MX.
