GeForce GTX 1660 vs Radeon RX 580X benchmarks

For gaming, the GeForce GTX 1660 graphics card is better than the Radeon RX 580X in our tests.

Our database shows that the GeForce GTX 1660 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 also has a slightly 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.

As stated by the manufacturer, the Radeon RX 580X has slightly more memory with 8 GiB of memory compared to 6 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the GeForce GTX 1660 has a significantly lower TDP at 120 W when compared to the Radeon RX 580X at 185 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

In conclusion, all specs and GPU benchmarks considered, will recommend the GeForce GTX 1660 over the Radeon RX 580X.
