The upcoming Radeon RX 6900 XT will have a higher GPU clock limit than the Radeon RX 6800 and Radeon RX 6800 XT, the flagship model from AMD will allow a frequency of up to 3.0GHz. VideoCardz says the limit seems to be a way from AMD to further differentiate the cards:
This limit is clearly AMD’s attempt to prevent a cheaper model from reaching a better performance than a much more expensive Radeon RX 6900 XT. If both SKUs were to offer the same limits, chances are that once overclocked the cut-down variant could easily reach RX 6900XT performance territory. After all, both cards have identical TGP (300W) and reference clock speeds.So far, no one has been able to circumvent the limit. Overall, this is not really a concern for the average user as these clockspeeds are not achievable with typical cooling.
The RX 6800 XT is limited to 2800 MHz... but not the RX 6900 XT. ???? pic.twitter.com/mw0udx9rqp— Patrick Schur (@patrickschur_) November 29, 2020
