Water-cooled variants are more common across the Nvidia lineup of GPUs than they are for AMD Radeon. Although that isn't changing, the gap is going to close by a small amount. Sapphire hasn't had a water-cooled variant in a while, but recent teasers suggest a new AIO-cooled Radeon RX 6900 XT. More specifically, a TOXIC variant of the 6900 XT.

The last time we saw a water-cooled variant was with the Sapphire RX 390X TOXIC & the generation before that RX 280X ATOMIC. From the teasers we have seen, it is likely that it will be the Radeon RX 6900 XT TOXIC variant as it features the yellow lighting seen on the RX 390X TOXIC. It might even be TOXIC ATOMIC because we saw a T and an A appear in the Chinese teaser.
