GeForce 920MX vs GeForce GTX 660 specs and performance

According to the hardwareDB Benchmark, the GeForce GTX 660 GPU is faster than the GeForce 920MX in gaming.

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 maximum frequency the chip can reach if power delivery and thermals allow.

In addition, the GeForce 920MX has a significantly lower TDP at 16 W when compared to the GeForce GTX 660 at 140 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 over the GeForce 920MX.
