Radeon RX 5600 XT vs GeForce GTX 660 comparison

For gaming, the Radeon RX 5600 XT graphics card is better than the GeForce GTX 660 in our tests.

Our database shows that the Radeon RX 5600 XT 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 5600 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.

Furthermore, the spec sheet for both these GPUs show that the Radeon RX 5600 XT has significantly more memory with 6 GiB of memory compared to 3 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 660 has a slightly lower TDP at 140 W when compared to the Radeon RX 5600 XT at 150 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

According to the results of the hardwareDB benchmark utility, the Radeon RX 5600 XT is faster than the GeForce GTX 660.
