The flagship Radeon RX 6900 XT graphics card will have the highest GPU clock speed of any Big Navi (RDNA 2) gas pedal. At least, according to the data from the informant Patrick Schur, published on Twitter.
According to the screen shots taken in the MorePowerTool utility, the future flagship Big Navi & ; Radeon RX 6900 XT & ; will be able to reach a higher clock frequency limit than graphics cards RX 6800 XT and RX 6800, & ; 3 GHz. The AMD Radeon RX 6800 XT, offering 72 Navi 21 processing units (CU), has a maximum GPU frequency tolerance of 2.8 GHz. This limit seems to be tightly set by AMD itself, and is enforced regardless of the modification of the graphics card by all partners; browsers and extreme overclockers have so far failed to overcome this limit. The restriction may be caused by the desire of AMD to prevent the cheaper model from competing with the much more expensive Radeon RX 6900 XT. If both gas pedals had the same frequency limit, there is a good chance that after overclocking the shortened version could easily approach the RX 6900XT in terms of performance. After all, both models have the same bass frequencies and a TBP (Total Board Power) limit of 300W. The AMD Radeon RX 6900 XT, which will offer 80 processing units, with an increased maximum clock speed limit of 3 GHz can be an excellent choice for overclockers, especially if the AMD will allow partners to produce unattended gas pedals. Overclocker Roman Hartung, known as der8auer, recently published a video in which he tried to overcome the 2.8 GHz limit on PowerColor's RX 6800 XT Red Devil. Unfortunately, despite many attempts, it is impossible to do it without special tools:
The AMD Radeon RX 6900 XT with 5120 streaming processors will compete with an NVIDIA GeForce RTX 3090 graphics card worth $1499. Both cards will surely set new world records for overclocking. Unfortunately, graphics gas pedal manufacturers will not be able to meet the huge demand for high-performance graphics cards, so at the recommended price of $999 will be able to buy 6900XT this year only a few select ones. AMD Radeon RX 6900 XT will officially enter the market on December 8.
