GeForce GTX 1660 vs Radeon RX 7900 XT comparison

For gaming, the Radeon RX 7900 XT graphics card is better than the GeForce GTX 1660 in our tests.

The Radeon RX 7900 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 7900 XT also has a slightly 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 7900 XT has significantly more memory with 20 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 has a significantly lower TDP at 120 W when compared to the Radeon RX 7900 XT at 315 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 7900 XT is faster than the GeForce GTX 1660.
