GeForce GTX 660M vs Radeon Vega 6 benchmarks

For gaming, the GeForce GTX 660M graphics card is better than the Radeon Vega 6 in our tests.

In our comparison, the GeForce GTX 660M 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. Despite this, the Radeon Vega 6 has a significantly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

In addition, the Radeon Vega 6 has a slightly lower TDP at 45 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 Radeon Vega 6.
