Radeon RX 6600 XT vs GeForce GTX 950M comparison

In our benchmarks, the Radeon RX 6600 XT beats the GeForce GTX 950M in gaming performance.

Our database shows that the Radeon RX 6600 XT 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 6600 XT also has a significantly 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 GTX 950M has a significantly lower TDP at 75 W when compared to the Radeon RX 6600 XT at 160 W. TDP (Thermal Design Power) measures total heat output from the chip.

In conclusion, all specs and GPU benchmarks considered, will recommend the Radeon RX 6600 XT over the GeForce GTX 950M.
