Radeon RX 560 vs GeForce GTX 660 comparison

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

In our comparison, the Radeon RX 560 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 560 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.

Furthermore, the spec sheet for both these GPUs show that the Radeon RX 560 has slightly more memory with 4 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 Radeon RX 560 has a significantly lower TDP at 80 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.

In conclusion, all specs and GPU benchmarks considered, will recommend the GeForce GTX 660 over the Radeon RX 560.
