GeForce 940M vs GeForce 840M benchmarks

In our benchmarks, the GeForce 940M beats the GeForce 840M in gaming performance.

In our comparison, the GeForce 840M 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 840M 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 840M 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.

In conclusion, all specs and GPU benchmarks considered, will recommend the GeForce 940M over the GeForce 840M.
