GeForce GTX 660 vs GeForce GTX 980M specs and performance

In our benchmarks, the GeForce GTX 980M beats the GeForce GTX 660 in gaming performance.

Our database shows that the GeForce GTX 980M 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 980M 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.

Next up, in terms of GPU memory, the GeForce GTX 980M has slightly more memory with 4 GiB of memory compared to 3 GiB. If you're planning at playing games at high resolutions with high-quality textures, you will need a lot of memory.

In addition, the GeForce GTX 980M has a slightly lower TDP at 100 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.

In conclusion, all specs and GPU benchmarks considered, will recommend the GeForce GTX 980M over the GeForce GTX 660.
