Radeon RX 560X vs GeForce 840M comparison

In our benchmarks, the Radeon RX 560X beats the GeForce 840M in gaming performance.

Our database shows that the Radeon RX 560X 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 Radeon RX 560X 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 840M has a significantly lower TDP at 33 W when compared to the Radeon RX 560X 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 Radeon RX 560X over the GeForce 840M.
