As per the tipster, he had received an internal non-public product-AMD RX 6900 XTX water-cooled version. It is said that this AMD public version of the water-cooled graphics card is called RX 6900 XTX and uses AIO integrated water-cooled heat dissipation.
AMD has also released similar graphics cards before, such as RX Vega 64 Liquid Edition and Radeon R9 Fury X. AMD recently released the Navi 21 GPU code-named XTXH for ultra-high-end water-cooled graphics cards, like ASRock’s RX 6900 XT OC Formula, Sapphire’s RX 6900 XT Toxic Extreme or Vibration’s RX 6900 XT Liquid. Devil Ultimate.
Several people speculate that AMD originally planned to use this specially selected Navi 21 GPU to build a public graphics card, but due to the very limited supply, AMD finally decided to hand over to partner manufacturers to build non-public graphics cards. AMD RX 6900 XT has 5120 stream processors and GDDR6 16GB large video memory.
