Radeon RX 640 vs GeForce MX350 comparison

In our benchmarks, the GeForce MX350 beats the Radeon RX 640 in gaming performance.

Our database shows that the Radeon RX 640 has a significantly 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 640 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 MX350 has a significantly lower TDP at 20 W when compared to the Radeon RX 640 at 50 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 MX350 over the Radeon RX 640.
