PowerColor has listed AMD's Radeon RX RX 6900 XT LC on their website, confirming the specification of AMD's leaked Radeon flagship. This new graphics card model is an AMD reference design that features a 120mm liquid cooling solution and features higher clock speeds than AMD's existing RX 6900 XT air-cooled designs. 

AMD has a long history of releasing liquid cooled graphics cards, such as their RX Fury X, RX Vega 64 LC, and RX 295x2. The RX 6900 XT LC appears to be AMD's continuation of this high-end liquid cooling trend, offering gamers higher core clock speeds and memory speeds than the company's existing air-cooled RX 6900 XT reference model. 

According to PowerColor's listing, AMD's Radeon RX 6900 XT LC graphics card features a "game clock" of 2250 MHz and 18Gbps GDDR6 memory. These changes indicate that AMD's RX 6900 XT LC features a game clock speed boost of around 11.7% and a VRAM bandwidth increase of 11.25% when compared to the company's reference air-cooled RX 6900 XT.  

Samsung confirmed in 2018 that they planned to produce 18Gbps GDDR6 memory modules, memory chips that are almost fast enough to enter GDDR6X performance levels. Using these modules, AMD can deliver more memory bandwidth on their flagship RDNA 2 silicon, leading to a significant performance boost in some memory-limited workloads.

Below are the specifications of AMD's RX 6900 XT LC, as listed by PowerColor. Below we have also included leaked imagery of a Sapphire RX 6900 XT LC graphics card, which appears to use an AMD/Radeon heatsink design.

Looks like a tidy solution at fist glance; but the sleeved cables zip tied to the hose look as though they are too short and zip ties on a premium of premium product? Please. The little details, guys; the little details.Quote

Looks like its designed to fit as an exhaust fan at rear of the case and no where else.Quote

It looks more like an after thought really, they shouldÂ’ve gone the Fractal route - hiding the fan cable inside of the sleeving.Quote

Not to mention a single 120 rad, as Alien mentioned in another thread. Rads are cheap, and these cards are ridiculously overpriced already, they can't make a 240 / 280 / 360 variant?Quote
