With the latest SUPER upgrades from Nvidia joining the company's extensive lineup of graphics cards, there has been some speculation that the green team could also release a SUPER variant of the top-end GeForce RTX 2080 Ti. Although an Nvidia executive has categorically stated there are no plans to release such a product, it may depend on what AMD has in store.

AMD can make RTX 2080Ti competitor even today, the only reason holding them back is the TSMC's available capacity on the 7nm, if TSMC could offer them Extra 7nm silicons for GPU's without hurting the Zen2 chiplets volume they AMD would put out RTX2080/2080TI killers cards already, until then they are making more money for Zen2 chiplets then they could on 300+mm2 GPU silicons with all the Extra BOM for working GPU.
for example Navi is 255mm2 and sells for $399 with all extra BOM parts vs 3950X @$749 that uses just two 7nm chiplets that are just 75mm2 each with much higher Yields since they are super tiny.
