GeForce GTX 1660 Ti vs GeForce GTX 660 Ti specs and performance

For gaming, the GeForce GTX 1660 Ti graphics card is better than the GeForce GTX 660 Ti in our tests.

In our comparison, the GeForce GTX 1660 Ti 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 GTX 1660 Ti also has a significantly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

As stated by the manufacturer, the GeForce GTX 1660 Ti has significantly more memory with 6 GiB of memory compared to 3 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the GeForce GTX 1660 Ti has a slightly lower TDP at 120 W when compared to the GeForce GTX 660 Ti at 150 W. Heat output doesn't match power consumption directly but, it's a good estimate.

In conclusion, all specs and GPU benchmarks considered, will recommend the GeForce GTX 1660 Ti over the GeForce GTX 660 Ti.
