GeForce GTX 660 vs GeForce 830M comparison

According to the hardwareDB Benchmark, the GeForce GTX 660 GPU is faster than the GeForce 830M in gaming.

The GeForce 830M 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 830M 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 830M has a significantly lower TDP at 33 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 660 over the GeForce 830M.
