The Radeon RX 6900 XT is now available for presale, and this Sapphire-branded GPU does not feature any of the characteristics of third-party GPUs. Instead, it appears to be a reference liquid-cooled design with a compact 120mm radiator.

Upon closer inspection, the shroud and cooler certainly look the part of AMD's RDNA 2 reference design.

The card is listed on Kabum (well found, Videocardz) and is listed as available starting June 30, 2021. We can also see an image of such a card previously posted on the Chinese forum Chiphell.

If this date makes sense, this retailer may have jumped on the broad announcement of a liquid-cooled RX 6900 XT from AMD. It is also possible that this card, which is in high demand and low supply, will only be released in certain markets, as the regular reference RX 6900 XT is now as scarce as a gold mine.

The specs for the remaining liquid-cooled RX 6900 XT are as follows: 5,120 cores, 80 CUs, 80 Ray accelerators, 16GB of GDDR6 memory at 16Gbps.

However, the liquid-cooled model differs in a few key areas: the GPU boost clock is set at 2,435 MHz, 185 MHz higher than the air-cooled reference card, and the memory is 18 Gbps.

The faster core clock is probably due to the improved cooling of the liquid-cooled card. The card may also have a Navi 21 XTX GPU, which is a binned variant of the GPU found on the first production run of the RX 6900 XT graphics card, which can run slightly faster.

This is not entirely new territory, at least for AMD; AMD has offered liquid-cooled reference cards in the past, such as the RX Vega 64 XTX, which was available through AMD partners including Sapphire. [However, the liquid-cooled RX Vega 64 was an incredibly limited run, and once the first wave of cards sold out, they virtually never came back. It was also quite expensive, and the same could be said for the liquid-cooled RX 6900 XT. In the list above, it costs 19,999 Brazilian reais (about US$4,000).

I have asked Sapphire for more information, but the card will not be officially released for some time now.
