PowerColor had recently launched the Radeon RX 6900 XT Liquid Devil Ultimate. For those wondering what the "Ultimate" signifies, basically, these are super-binned versions of the regular Liquid Devil, the best of the best silicon which are expected to reach the highest clocks possible. In fact, today, overclocking guru der8auer has set an all-time core clock speed record with the Liquid Devil Ultimate. And for that to be possible, the Ultimate has a card up its sleeve.
Unlike the regular Navi 21 XTX inside the other 6900 XTs, the Devil Ultimate and other such binned 6900 XT GPUs feature the Navi 21 XTXH, and the XTXH chips do not have the imposed 3GHz clock limit on them. Otherwise, this new record couldn't have existed as the Liquid Devil Ultimate was able to reach 3,225 MHz breaking the previous record of 3,012 MHz held by a GTX 1080.
Below you can see the picture of the Liquid Devil Ultimate in its natural habitat and the GPU-Z screenshot at its overclocked state of 3,225MHz.
The PowerColor Liquid Devil Ultimate RX 6900 XT comes with a rated boost clock of 2,525 MHz in the "Unleash" mode so the world record speed achieved today is around ~20% higher. In terms of hardware specifications, like the regular Liquid Devil, the Ultimate also packs 80 Compute Units (CUs), 16GB of GDDR6 memory, and 128 MB of on-die Infinity Cache.
