According to details provided by Zotac, the new RTX 2080 Ti ArcticStorm uses a custom PCB with high-end 16+4-phase VRM and a special liquid cooling block with integrated Spectra 2.0 RGB lighting.
While there are no specific details regarding the actual clocks, it is possible that we will see even higher clocks than on the Zotac RTX 2080 Ti AMP! Extreme graphics card.
Hopefully, the card will be up and running at the CES 2019 floor and Zotac will give more details on its actual performance as well as the release date and the price.
