Radeon RX 580 vs GeForce GTX 660 Ti specs and performance

In our benchmarks, the Radeon RX 580 beats the GeForce GTX 660 Ti in gaming performance.

Our database shows that the Radeon RX 580 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 580 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 580 has significantly more memory with 8 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 Ti has a slightly lower TDP at 150 W when compared to the Radeon RX 580 at 185 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 580 is better than the GeForce GTX 660 Ti.
