Software engineer Patrick Schur has tweeted some interesting information pertaining to AMD’s new Radeon RX 6000 Series graphics cards. Apparently, the Radeon RX 6800 XT is limited to 2.8 GHz, but red team’s flagship GPU, the Radeon RX 6900 XT, can reach clocks of up to 3.0 GHz.
It isn’t clear why there’s a discrepancy in the clock limits between the Radeon RX 6800 XT and Radeon RX 6900 XT. Some users believe that the limitation is legitimate (e.g., silicon related), while others claim that AMD has intentionally restricted the ceiling of the Radeon RX 6800 XT to make the Radeon RX 6900 XT even more attractive to prospective buyers.
In any case, the implication here is that the Radeon RX 6900 XT will definitely be the card of choice for extreme overclockers who wish to set new records and see what AMD’s RDNA 2 architecture is truly capable of.
Popular overclocker der8auer has shared a video acknowledging the BIOS limit that’s presumably present in all Radeon RX 6800 XT graphics cards. der8auer tried to get around the artificial 2.8 GHz limitation on his PowerColor Red Devil, but his efforts were seemingly in vain.
