GeForce GTX 660 Ti vs GeForce 940MX specs and performance

According to the hardwareDB Benchmark, the GeForce GTX 660 Ti GPU is faster than the GeForce 940MX in gaming.

The GeForce 940MX 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 940MX 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 940MX has a significantly lower TDP at 23 W when compared to the GeForce GTX 660 Ti at 150 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

In conclusion, all specs and GPU benchmarks considered, will recommend the GeForce GTX 660 Ti over the GeForce 940MX.
