GeForce GTX 1660 SUPER vs Radeon RX 5600 XT comparison
In our benchmarks, the Radeon RX 5600 XT beats the GeForce GTX 1660 SUPER in gaming performance.
In our comparison, the GeForce GTX 1660 SUPER has a slightly 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. In addition, the GeForce GTX 1660 SUPER 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 6 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.
In addition, the GeForce GTX 1660 SUPER has a slightly lower TDP at 125 W when compared to the Radeon RX 5600 XT at 150 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 RX 5600 XT over the GeForce GTX 1660 SUPER.
