GeForce GTX 1080 Ti vs GeForce GTX 1660 SUPER benchmarks
For gaming, the GeForce GTX 1080 Ti graphics card is better than the GeForce GTX 1660 SUPER in our tests.
The GeForce GTX 1660 SUPER 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 SUPER also has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.
Next up, in terms of GPU memory, the GeForce GTX 1080 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 SUPER has a significantly lower TDP at 125 W when compared to the GeForce GTX 1080 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 GTX 1080 Ti is better than the GeForce GTX 1660 SUPER.
