Zotac's RTX 2080 AMP Extreme has the highest GPU clocks of all RTX 2080 cards released so far, and its memory is overclocked, too. The VRM has been massively upgraded, featuring a total of 20 phases! Unlike previous cards, the AMP Extreme has Samsung memory, which overclocks much better than Micron.
