GeForce GTX 950M vs GeForce GTX 660M benchmarks

For gaming, the GeForce GTX 950M graphics card is better than the GeForce GTX 660M in our tests.

In our comparison, the GeForce GTX 950M 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 950M 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 GTX 660M has a significantly lower TDP at 50 W when compared to the GeForce GTX 950M at 75 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 950M is faster than the GeForce GTX 660M.
