AMD's Radeon RX 6900 XT, the flagship Big Navi GPU based graphics card, launches next month & is expected to compete against the GeForce RTX 3090. Twitter fellow, Patrick Schur, managed to get access to the BIOS of the reference AMD Radeon RX 6900 XT which reveals a higher max frequency than the RX 6800 XT.

AMD Radeon RX 6900 XT Max Clocks Rated at 3.0 GHz, 200 MHz Higher Than The Radeon RX 6800 XT
The BIOS was accessed and its specifics were listed within the MorePowerTool which lists down various parameters such as clocks, the power limit, and fan speeds. The AMD Radeon RX 6900 XT seems to feature the same fan profiles and power limits as the RX 6800 XT however, the minimum power limit is raised from 6% to 10%.

The AMD Radeon RX 6900 XT features more than just higher clocks. It has more cores and a faster-binned GPU which should allow for faster and more stable clocks. It looks like the Radeon RX 6900 XT will be breaking some big world records when it launches. The card is expected to launch first in reference flavors only but users shouldn't give up hopes on getting custom models in the future or at least when the RX 6000 series supply gets better.

The AMD Radeon RX 6900 XT will come packed with the Navi 21 XTX GPU which is the fully enabled die featuring 80 Compute Units or 5120 SPs. The card will also feature 16 GB of GDDR6 memory across a 256-bit bus interface, a 512 GB/s total bandwidth, and clock speeds of 2015 MHz base and 2250 MHz boost at reference specs. There are also 80 Ray accelerators for ray-tracing enablement on the graphics cards (one RA per Compute Unit). The graphics card will feature a TBP of 300W.

Can't wait for the card that's going to take on the BFGPU.......The 6900XT lands on the 8th of December, about a week's time from now....

Care to address this after your original comments in the 6800XT/6900XT reveal thread?

The difference in architecture makes all the difference.

those are the bios limit clocks. Very few will go past 2800mhz for sure. On the 6800XT the limit is 2800mhz but only a few cards hit 2700mhz.

Crazy clocks none the less.

Wow 80 CUs @ max 3ghz, this is gonna be a monster.

It's unlikely that the reference cards will hit those frequencies if the reference 6800xt cooler is anything to go by (while overall ok, it's still lacking in some key areas).

We will definitely see some interesting results from AIB's though.

Whether it will be enough to take the performance well clear of the 3090 remains to be seen.

LoL all gpus have boost table going into unreachable numbers

Its been true to say that so far. But the some 6800XT AIB are into the 27xxmhz already. Less than 100mhz away from the hard limit. Thus, the video der8auer made complaining about it.

Hope the performance difference between it and the 3080 is big enough.
Very unlikely, it's just 8 extra CUs (and it's always more difficult to use extra CUs as you increase them). Maybe in the long run it will pull away more as new games get developed around RDNA2 consoles, but I wouldn't expect much past parity at launch.

Not that it matters much, I reckon there will be fuck all 6900XTs on the market, even beyond the next 3-4 months, simply because it's a perfect chip & those will be very scarce.

that will only materialize on LN2 and maybe on water
Given that the 6800XT can do 2750MHz on air, I think water might get it close. LN2, once the bios limiters are removed should go well past 3GHz.
Baring in mind that the 6900XT is a better bin than the 6800XT.

It seems like there's a real tangible difference in clocks and performance on the higher binned chips the AIBs are putting in their premium models. Last I checked it's still up in the air whether or not we get AIB 6900 XTs, but if we do, some of these cards are going to be absolute monsters.
