AMD was planning to release a Radeon RX 6900 XTX graphics card with liquid cooling, according to leaked photos. It uses a factory pre-binned Navi 21 XTXH GPU, the same chip used in select high-end AIB models. The AIO appears to be similar to the ones seen on the Radeon RX Vega 64 Liquid Cooled Edition and Radeon R9 Fury X. It is believed that AMD decided not to release it due to limited GPU supply.
The graphics card is named directly as RX 6900 XTX. The source actually quotes Chiphell where apparently someone shared pictures of an evaluation board featuring AMD’s new reference design. The graphics card features a built-in AIO cooling, similar to other power-hungry SKUs that AMD released in the past, such as RX Vega 64 Liquid Edition or Radeon R9 Fury X.
