Radeon RX 5500 vs GeForce GTX 660 benchmarks

In our benchmarks, the Radeon RX 5500 beats the GeForce GTX 660 in gaming performance.

Our database shows that the Radeon RX 5500 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 5500 also has a significantly 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 5500 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 GeForce GTX 660 has a slightly lower TDP at 140 W when compared to the Radeon RX 5500 at 150 W. Heat output doesn't match power consumption directly but, it's a good estimate.

In conclusion, all specs and GPU benchmarks considered, will recommend the Radeon RX 5500 over the GeForce GTX 660.
