AMD Radeon RX 6900 XT sets new world record at 3.2GHz

Overclocker Der8auer set a new world record with the AMD Radeon RX 6900 XT. In a YouTube video released Wednesday, the German overclocking legend used a liquid nitrogen cooling rig to push AMD’s flagship Big Navi GPU to 3.2GHz, setting a new world record for graphics card speed. The 6900 XT is already an absurdly fast graphics card with a boost clock of 2.25GHz, but Der8auer was able to take the card 1GHz beyond even its fastest speed.

The clock speed goes beyond the artificial clock limit of 3.0GHz on the 6900 XT. That’s because Der8auer was using a PowerColor LiquidDevil Ultimate card, which has a clock limit of 4GHz. It uses the updated XTXH variant of the Navi 21 processor inside the 6900 XT, upping the previous version’s frequency limit.

The LiquidDevil Ultimate uses binned GPUs — meaning silicon that has been vetted for high overclocking potential — and features 16-phase VRM for excellent power management. It’s a card made for this kind of extreme overclocking, so it was inevitable that someone would set a world record.

Although the LiquidDevil Ultimate comes with a water block pre-installed, Der8auer stripped the PCB to attach an LN2 cooling chamber, pushing the card to sub-zero temperatures to create an optimal overclocking environment. He also used a custom BIOS, as nearly all extreme overclockers do, and said it will be released into the wild soon.

It was only for a split second, but Der8uer achieved a clock speed of 3,225MHz on the card before crashing. At the end of the video, he said the card has “enormous potential, at least for extreme overclocking,” and that other cards may be able to hit speeds as high as 3.5GHz.

But that’s getting into the territory of high-end, heavily-binned GPUs, and most gamers and hardware enthusiasts would be happy getting their hands on a 6900 XT at all. Like previous world records, this one is cause for celebration. However, it comes amid one of the worst GPU shortages the market has seen, which may not fully recover until 2022.

Radeon RX 7900 XTX vs. RX 7900 XT: AMD’s monster GPUs, compared
RX 7900 XTX and RX 7900 XT on a pink background.

The long-awaited RX 7000 series has finally arrived, or more specifically, AMD's two top-end GPU flagships have. The 7900 XT and the 7900 XTX are set to go head-to-head with the Nvidia RTX 4080, although they may not keep up with the RTX 4090.

Given how different the 4080 and 4090 are from each other, you might wonder if the same thing is going on with the 7900 XT and the 7900 XTX. Here's everything we know so far.

What power supply do you need for the AMD Radeon RX 7900 XTX?

Upgrading your graphics card can sometimes mean upgrading your power supply too, especially if it's one of the latest generations of flagship cards, like the AMD Radeon RX 7900 XTX. If you want to make sure everything's smooth and stable, it's best to check whether your current PSU can handle the upgrades provided by AMD's new range of GPUs, dubbed RDNA 3 or Radeon RX 7000.

So far, the new GPU range only has two cards: the RX 7900 XTX and the 7900 XT. Out of those two, the RX 7900 XTX is the one that consumes the most power. Even then, it's still fairly conservative when compared to the Nvidia flagship, the RTX 4090. In Nvidia's case, the Founders Edition has a total board power (TBP) of 450 watts and calls for an 850-watt PSU. However, some of Nvidia's board partners that made custom versions of the GPU require a much beefier PSU, reaching as high as 1,200 watts.
