PowerColor has lifted the curtains on the brand's Liquid Devil Radeon RX 6900 XT and RX 6800 XT. The new graphics cards arrive with a full-cover EKWB designed waterblock and are ready to be integrated into your custom watercooling system.

The Liquid Devil Radeon RX 6900 XT and RX 6800 XT jump out of the same mold. Both offerings measure 266 x 162 x 42mm while only requiring two slots from your case. PowerColor has outfitted the RDNA 2 graphics cards with a 14+2-phase power delivery subsystem to unleash Big Navi's full potential without any compromises. 

Both of the cards come with 16GB GDDR6 of memory but their clock speeds differ, with the RX 6900 XT offering a 2,135 MHz game clock, and 2,365 MHz boost and the 6800 XT coming in at a slightly slower 2,110 MHz and 2,360 MHz respectively. Powercolor has also implemented high polymer capacitors into the card that can deal with over 400W of power. Naturally, the EKWB waterblock plays an important role in cooling the graphics cards.

The waterblock features a nickel-plated copper baseplate that effectively transfers the heat away from the GPU. It features a full-cover design that covers all the important components inside the graphics card, such as the GPU, memory and PWM. The waterblock is partially made from acrylic so it also offers some RGB flair. A matching aluminum backplate rounds out the design.

The perks of putting a graphics card under liquid cooling include performance and silence. In regards to performance, Liquid Devil models are up to 6% and 5% faster than AMD's reference specification.

Since not everyone wants to go all out on performance, PowerColor added a handy switch on the graphics card to switch between the vBIOS profiles. Both the Liquid Devil Radeon RX 6900 XT and RX 6800 XT come with two operational modes: Unleash for the utmost performance and OC for stable overclocked performance.

The graphics cards require three 8-pin PCIe power connectors to function correctly. PowerColor recommends a power supply that has a minimum capacity of 900W to feed these monsters. As for display outputs, both offer one HDMI 2.1 port and two DisplayPort 1.4 outputs and the USB Type-C port.

The Liquid Devil Radeon RX 6900 XT and RX 6800 XT will be available starting March 15, but PowerColor didn't reveal their pricing.

    Being as these require custom watercooling loops, I wonder if they will have a little more availability than air cooled cards.

    Or they'll have less availability as most places don't like stocking water cooled cards in significant numbers.
