PowerColor has unveiled Ultimate editions of its top-of-the-range Red Devil Radeon RX 6900 XT and Liquid Devil Radeon RX 6900 XT graphics cards with hand-selected GPUs that guarantee a great overclocking potential.

The new Red Devil Radeon RX 6900 XT Ultimate and Liquid Devil Radeon RX 6900 XT Ultimate use exactly the same custom PCB design with a 14+2-phase voltage regulating module (VRM) as well as three eight-pin auxiliary power connectors and cooling systems as their regular versions introduced earlier this year.  

Their key difference of the Ultimate boards from their predecessors is frequency of the Navi 21 XTX GPU (5120 stream processors, 320 TUs, 128 ROPs, 80 RT units). The Red Devil RX 6900 XT Ultimate can boost its Navi 21 GPU to 2425 MHz, whereas the Liquid Devil RX 6900 XT Ultimate can boost its graphics processor to 2525 MHz. To put the numbers into context, AMD's reference Radeon RX 6900 XT does not go higher than 2250 MHz.

In addition to higher clocks, the Red Devil Radeon RX 6900 XT Ultimate is programmed to deliver up to 303W to the GPU, whereas the Liquid Devil Radeon RX 6900 XT Ultimate can deliver up to 332W to the GPU in a bid to further increase their overclocking potential beyond what PowerColor offers out-of-box.

We recently reported that early reviewers of PowerColor's Ultimate Red Devil Radeon RX 6900 XT had discovered that the graphics card carried a Navi 21 XTX GPU which featured an id/firmware which GPU-Z did not recognize. The new identification implied that they were dealing with a die binned by AMD for higher clocks that even received a new designation (Navi 21 XTXH) and id. PowerColor says that its Ultimate graphics cards carry GPUs cherry-picked by the graphics cards maker. 

"Every overclocker knows that every GPU is different; sometimes, one can get lucky and find a card that can be highly overclocked due to the silicon lottery," a statement by PowerColor reads. "With the PowerColor Red Devil Ultimate and Liquid Devil Ultimate cards, you remove the element of chance and guarantee a specially binned GPU with exceptional overclocking — PowerColor assures performance every time."

Like every other semiconductor companies, AMD and its manufacturing partner TSMC have continuous process improvements (CPI) protocols in place and constantly analyze every new batch of chips they produce. Over time, they can improve yields and reduce performance variations, which either reduces costs of higher-end units or opens doors to binning for parts with higher overclocking potential.

For AMD, it does not make much sense to cherry pick GPUs with the highest frequency potential amid dramatic shortages as additional binning takes time, costs money, and creates demand for SKUs that are by definition rare. Graphics cards manufacturers tend to differentiate themselves from their rivals by offering boards with the highest GPU and memory clocks, so cherry-picking GPUs is not something completely new for them (something that EVGA has done for its K|NGP|N cards). However, such cherry-picked GPUs never come with new id/firmware as the latter are AMD's prerogative. That said, it is still unclear whether AMD decided to sell crème-de-la-crème Navi 21 XTX GPUs at a premium, or gave its partners a new degree of freedom with factory-overclocked products.

PowerColor will offer two versions of its Red Devil Radeon RX 6900 XT: the vanilla AXRX 6900XT 16GBD6-3DHE/OC and the AXRX 6900XT 16GBD6-2DHCE/OC Limited Edition. The default board will feature three DisplayPort 1.4 outputs and two HDMI connectors, whereas the LE card will have a USB-C port instead of one DP 1.4 and a bundled Red Devil keycap for mechanical keyboards. 

Right now we have no indications as to their price.
