GeForce GTX 660 vs GeForce 930MX benchmarks

For gaming, the GeForce GTX 660 graphics card is better than the GeForce 930MX in our tests.

The GeForce GTX 660 has a slightly higher core clock speed. This is the frequency at which the graphics core is running at. While not necessarily an indicator of overall performance, this metric can be useful when comparing two GPUs based on the same architecture. 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 930MX has a significantly lower TDP at 17 W when compared to the GeForce GTX 660 at 140 W. TDP (Thermal Design Power) measures total heat output from the chip.

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