A few interesting pictures were posted on Weibo (a Chinese microblogging website) which appear to show an AMD Radeon RX 6900 XTX engineering sample. The card shown features an all-in-one (AIO) water-cooled design with a 120 mm radiator, much like what we saw on AMD’s Radeon R9 Fury and RX Vega 64 Liquid Edition.
Powering this card is the Navi 21 XTXH silicon. This new silicon is a higher binned Navi 21 XTX and features better overclocking potential. This new silicon we know will power at least three after-market cards including the PowerColor RX 6900 XT Liquid Devil Ultimate, ASRock RX 6900 XT OC Formula, and Sapphire RX 6900 XT Toxic Extreme. It appears as if AMD will be launching their own reference design of the card as well, although it is not clear as this is just an engineering sample.
