GeForce GTX 1660 vs Radeon RX 6500 XT benchmarks
For gaming, the GeForce GTX 1660 graphics card is better than the Radeon RX 6500 XT in our tests.
In our comparison, the Radeon RX 6500 XT 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. In addition, the Radeon RX 6500 XT also has a significantly higher boost clock speed. The boost clock speed is the frequency that the GPU core can reach if the temperature is low enough. The allows for higher performance in certain scenarios.
Furthermore, the spec sheet for both these GPUs show that the GeForce GTX 1660 has significantly more memory with 6 GiB of memory compared to 4 GiB. Lots of memory is good when playing at high resolutions or with many monitors.
In addition, the Radeon RX 6500 XT has a slightly lower TDP at 107 W when compared to the GeForce GTX 1660 at 120 W. Heat output doesn't match power consumption directly but, it's a good estimate.
In terms of raw gaming performance in our GPU benchmark, the GeForce GTX 1660 is better than the Radeon RX 6500 XT.
