AMD's unreleased Radeon RX 6900 XTX Liquid Cooled graphics card featuring the Big Navi 21 XTX GPU has been pictured. The graphics card, which will never be released in the consumer segment, was going to be a liquid-cooled variant of the existing RX 6900 XT graphics card but was canceled due to unknown reasons.

The AMD Radeon RX 6900 XT reference model comes with a triple-fan cooling solution but it looks like AMD had initially planned to offer a liquid-cooled variant too. This graphics card was going to be known as the Radeon RX 6900 XTX Liquid Cooled and as such, came with an AIO liquid cooling solution to cool down the Big Navi 21 XTX GPU.
