GeForce RTX 2080 SUPER vs GeForce GTX 660 specs and performance

For gaming, the GeForce RTX 2080 SUPER graphics card is better than the GeForce GTX 660 in our tests.

The GeForce RTX 2080 SUPER has a significantly 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 GeForce RTX 2080 SUPER 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 GeForce RTX 2080 SUPER has significantly more memory with 8 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 GeForce GTX 660 has a significantly lower TDP at 140 W when compared to the GeForce RTX 2080 SUPER at 250 W. TDP (Thermal Design Power) measures total heat output from the chip.

In conclusion, all specs and GPU benchmarks considered, will recommend the GeForce RTX 2080 SUPER over the GeForce GTX 660.
