GeForce GTX 1660 Ti vs GeForce RTX 2080 Ti specs and performance
For gaming, the GeForce RTX 2080 Ti graphics card is better than the GeForce GTX 1660 Ti in our tests.
Our database shows that the GeForce GTX 1660 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 GTX 1660 Ti also has a slightly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.
Next up, in terms of GPU memory, the GeForce RTX 2080 Ti has significantly more memory with 11 GiB of memory compared to 6 GiB. Lots of memory is good when playing at high resolutions or with many monitors.
In addition, the GeForce GTX 1660 Ti has a significantly lower TDP at 120 W when compared to the GeForce RTX 2080 Ti at 250 W. TDP (Thermal Design Power) measures total heat output from the chip.
In terms of raw gaming performance in our GPU benchmark, the GeForce RTX 2080 Ti is better than the GeForce GTX 1660 Ti.
