Radeon Vega 8 vs GeForce GTX 660M comparison

In our benchmarks, the Radeon Vega 8 beats the GeForce GTX 660M 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 Radeon Vega 8 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 8 has a slightly lower TDP at 45 W when compared to the GeForce GTX 660M at 50 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 Vega 8 over the GeForce GTX 660M.
