UHD 620 vs GeForce GTX 660M comparison

In our benchmarks, the GeForce GTX 660M beats the UHD 620 in gaming performance.

In our comparison, the GeForce GTX 660M has a significantly higher core clock speed. The core clock speed (or base speed) is the frequency at which the GPU core runs. This metric makes sense when comparing GPUs of a similar architecture or generation. Despite this, the UHD 620 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 UHD 620 has a significantly lower TDP at 15 W when compared to the GeForce GTX 660M at 50 W. TDP (Thermal Design Power) measures total heat output from the chip.

In conclusion, all specs and GPU benchmarks considered, will recommend the GeForce GTX 660M over the UHD 620.
