PowerColor quietly launched the Radeon RX 6900 XT Red Devil Ultimate graphics card. Not to be confused with the RX 6900 XT Red Devil Limited Edition, which is essentially an RX 6900 XT Red Devil with a few more accessories in the box; the new Red Devil Ultimate ships with higher factory-overclocked speeds. The default "OC" BIOS runs the card at 2235 MHz game clocks and 2425 MHz max boost frequency; compared to 2105 MHz game and 2340 MHz max boost frequency on the standard RX 6900 XT Red Devil. The silent BIOS of the Red Devil Ultimate runs it at 2135/2335 MHz, which is the same as the "OC" BIOS on the standard Red Devil.
HotHardware, which reviewed the card, reports that the Radeon RX 6900 XT Red Devil Ultimate is based on a higher bin of the "Navi 21" silicon. Our own sources tell us that this card is part of a new wave of RX 6900 XT custom-design graphics cards that AMD partners will be launching in the coming days, based on higher bins of the silicon, enabling both higher clocks on the tin, and better boost frequency sustainability.
Update 17:26 UTC: The Red Devil Ultimate is based on AMD's new Navi 21 XTXH GPU, which has the device ID 0x73AF, whereas all existing Navi 21 variants are 0x73BF. There's claims that XTXH is a special bin with better OC potential, lower leakage, etc. Whether that is true is unknown at this time, it's also unknown whether these cards come with truly increased OC adjustment limits in Wattman, or whether a special BIOS/driver is necessary. Next GPU-Z release will add proper detection for Navi 21 XTXH.
