GeForce GTX 1080 Ti vs GeForce RTX 2080 SUPER benchmarks
For gaming, the GeForce RTX 2080 SUPER graphics card is better than the GeForce GTX 1080 Ti in our tests.
The GeForce RTX 2080 SUPER has a slightly 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 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 GTX 1080 Ti has slightly more memory with 11 GiB of memory compared to 8 GiB. If you're planning at playing games at high resolutions with high-quality textures, you will need a lot of memory.
In addition, both the GeForce GTX 1080 Ti and the GeForce RTX 2080 SUPER have an identical TDP. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.
In conclusion, all specs and GPU benchmarks considered, will recommend the GeForce RTX 2080 SUPER over the GeForce GTX 1080 Ti.
