GeForce RTX 2080 Ti vs GeForce GTX 660 specs and performance

According to the hardwareDB Benchmark, the GeForce RTX 2080 Ti GPU is faster than the GeForce GTX 660 in gaming.

In our comparison, the GeForce RTX 2080 Ti has a slightly 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 GeForce RTX 2080 Ti 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 Ti has significantly more memory with 11 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 Ti at 250 W. TDP (Thermal Design Power) measures total heat output from the chip.

According to the results of the hardwareDB benchmark utility, the GeForce RTX 2080 Ti is faster than the GeForce GTX 660.
