Specifications of the AMD Navi 21 XT "Big Navi" GPU for the Radeon RX 6900 XT graphics card have been reported by Patrick Schur who has been very credible regarding his information.

According to the reported specs, the AMD Radeon RX 6900 XT seems to be a beast of a graphics card with insane clocks.

As per previous reports, the 21 XT GPU will be featured on the Radeon RX 6900 XT graphics card but there are also reports that a faster XTX variant exists which would be even faster.

The Navi 21 XT GPU will reportedly be a powerhouse of a chip with a game clock of around 2.4 GHz which are the highest clock speeds we will get to see on a consumer desktop-grade graphics card.

The graphics card based on the Navi 21 XT GPU, which is reportedly the Radeon RX 6900 XT, is said to feature 16 GB of GDDR6 memory which is also what we've seen in various previous leaks.

As for comparative measurements, the performance looks to be really close to the NVIDIA GeForce RTX 3080 graphics card which is very impressive for AMD to hit, and if they can price the Big Navi graphics card right at around $499-$599 US, then they will have a killer 4K solution in their hands.
