GeForce GTX 1660 Ti vs Radeon RX 6600 XT comparison

In our benchmarks, the Radeon RX 6600 XT beats the GeForce GTX 1660 Ti in gaming performance.

In our comparison, the Radeon RX 6600 XT 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 6600 XT also 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.

As stated by the manufacturer, the Radeon RX 6600 XT has slightly more memory with 8 GiB of memory compared to 6 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the GeForce GTX 1660 Ti has a slightly lower TDP at 120 W when compared to the Radeon RX 6600 XT at 160 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 6600 XT over the GeForce GTX 1660 Ti.
