GeForce GTX 1080 vs Radeon RX 6600M comparison

In our benchmarks, the GeForce GTX 1080 beats the Radeon RX 6600M in gaming performance.

In our comparison, the Radeon RX 6600M has a slightly 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. In addition, the Radeon RX 6600M also has a slightly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

As stated by the manufacturer, they both have the same amount of memory at 8 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the Radeon RX 6600M has a significantly lower TDP at 100 W when compared to the GeForce GTX 1080 at 180 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 GeForce GTX 1080 over the Radeon RX 6600M.
