The maximum GPU frequency of AMD Radeon RX 6900 XT reaches 3 GHz
|The flagship Radeon RX 6900 XT graphics card will have the highest maximum GPU clock rate among all Big Navi (RDNA 2) accelerators. At least, according to the informant Patrick Schur (Patrick Schur), published on Twitter. |
According to screenshots taken in the MorePowerTool utility, the future flagship of Big Navi-Radeon RX 6900 XT-will be able to reach a higher clock speed limit than the RX 6800 XT and RX 6800 video cards — 3 GHz.
The AMD Radeon RX 6800 XT, which offers 72 Navi 21 compute units (CU), has a maximum allowable GPU frequency of 2.8 GHz. This limit seems to be rigidly set by AMD itself, and is observed regardless of the video card modification by all partners-reviewers and extreme overclockers have not yet been able to overcome this limit.
The restriction may be caused by AMD's desire to prevent the cheaper model from competing with the much more expensive Radeon RX 6900 XT. If both accelerators had the same frequency limits, it is likely that after overclocking, the stripped-down version could easily get somewhat closer in performance to the RX 6900XT. After all, both models have the same base frequencies and a 300W TBP (Total Board Power) power limit.
