GeForce GTX 950 vs GeForce GTX 660M comparison

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

The GeForce GTX 950 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 950 also has a slightly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

As stated by the manufacturer, they both have the same amount of memory at 2 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the GeForce GTX 660M has a significantly lower TDP at 50 W when compared to the GeForce GTX 950 at 90 W. TDP (Thermal Design Power) measures total heat output from the chip.

In terms of raw gaming performance in our GPU benchmark, the GeForce GTX 950 is better than the GeForce GTX 660M.
