Radeon RX 480 vs GeForce GTX 660 comparison

For gaming, the Radeon RX 480 graphics card is better than the GeForce GTX 660 in our tests.

Our database shows that the Radeon RX 480 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 480 also has a slightly higher boost clock speed. The boost clock speed is the frequency that the GPU core can reach if the temperature is low enough. The allows for higher performance in certain scenarios.

Next up, in terms of GPU memory, the Radeon RX 480 has significantly more memory with 8 GiB of memory compared to 3 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the GeForce GTX 660 has a slightly lower TDP at 140 W when compared to the Radeon RX 480 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 conclusion, all specs and GPU benchmarks considered, will recommend the Radeon RX 480 over the GeForce GTX 660.
