GeForce 830M vs GeForce 940M benchmarks

According to the hardwareDB Benchmark, the GeForce 830M GPU is faster than the GeForce 940M in gaming.

In our comparison, 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 940M at 75 W. Heat output doesn't match power consumption directly but, it's a good estimate.

According to the results of the hardwareDB benchmark utility, the GeForce 830M is faster than the GeForce 940M.
