GeForce GTX 1660 vs Radeon RX 6600 comparison

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

Our database shows that the Radeon RX 6600 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 Radeon RX 6600 also has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

As stated by the manufacturer, the Radeon RX 6600 has slightly more memory with 8 GiB of memory compared to 6 GiB. If you're planning at playing games at high resolutions with high-quality textures, you will need a lot of memory.

In addition, the GeForce GTX 1660 has a slightly lower TDP at 120 W when compared to the Radeon RX 6600 at 132 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 Radeon RX 6600 over the GeForce GTX 1660.
