More information regarding the clock speeds for the AMD Radeon RX 6800 XT custom "Big Navi" graphics cards have leaked out by Patrick Schur. In his latest tweet, Patrick talks about the AMD Radeon graphics card, the ROG STRIX Radeon RX 6800 XT from ASUS, which reportedly comes with boost clocks beyond 2.5 GHz.

The information is based on engineering board samples so final clocks and TGPs may vary but it is interesting just how far AIBs have managed to push AMD's Big Navi GPUs, even if internally. ASUS's ROG STRIX Radeon RX 6800 XT is the highlighted model today & there are three systems mentioned by Patrick that have been tested within 3DMark 11, all with variable clock speeds. The RX 6800 XT is reportedly running with a set TGP of 290W and a 1000 MHz memory clock which represents 16.00 Gbps memory dies.
