Radeon RX 6500 XT vs GeForce GTX 660 Ti comparison

For gaming, the Radeon RX 6500 XT graphics card is better than the GeForce GTX 660 Ti in our tests.

Our database shows that the Radeon RX 6500 XT has a significantly 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 6500 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.

Next up, in terms of GPU memory, the Radeon RX 6500 XT has slightly more memory with 4 GiB of memory compared to 3 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the Radeon RX 6500 XT has a slightly lower TDP at 107 W when compared to the GeForce GTX 660 Ti 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.

In terms of raw gaming performance in our GPU benchmark, the Radeon RX 6500 XT is better than the GeForce GTX 660 Ti.
