Radeon RX 560X vs GeForce GTX 660 comparison

According to the hardwareDB Benchmark, the GeForce GTX 660 GPU is faster than the Radeon RX 560X in gaming.

In our comparison, the Radeon RX 560X 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 560X 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 560X 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 560X has a significantly lower TDP at 75 W when compared to the GeForce GTX 660 at 140 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 GeForce GTX 660 is faster than the Radeon RX 560X.
