GeForce GTX 660M vs Radeon RX Vega 11 specs and performance

According to the hardwareDB Benchmark, the Radeon RX Vega 11 GPU is faster than the GeForce GTX 660M in gaming.

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 RX Vega 11 has a significantly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

In addition, the Radeon RX Vega 11 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 terms of raw gaming performance in our GPU benchmark, the Radeon RX Vega 11 is better than the GeForce GTX 660M.
