We point out that these numbers are highly theoretical and far above of what these GPUs get at stock settings. Both the Radeon RX 6800 XT and 6900 XT have a nominal boost clock of 2,250 MHz. So unless you are using liquid nitrogen or other aggressive cooling methods, it is unlikely that you will reach or be able to exceed the indicated limit of 2. , 8 GHz on the 6800 XT, 3GHz on the 6900 XT and, finally, 2.95 GHz on the 6700 XT.

It makes sense that the RX 6900 XT has the highest frequency limit, as this is AMD's top-of-the-line GPU and will presumably use the best components. But the really interesting thing is that the RX 6700 XT is assumed to have a maximum clock of 2,950 MHz, while the RX 6800 XT reaches 2.8 GHz. This indicates that the 6700 XT could really be an overclocking marvel.

IgorsLAB dug a little more into the BIOS of the RX 6700 XT, finding that AMD's partner BIOSes have much higher power limits and a higher core voltage than the reference RX 6800. The first BIOS (which Igor thinks is for reference) points to 186W of TGP, while the second goes up to 211W.
If this is true and the RX 6700 XT cards will offer these specifications, we could see on the graphics card market with factory overclocking quite high. The 40 CUs on the RX 6700 XT would potentially be powered with more power, allowing for higher frequencies. Furthermore, the presence of only 40 CUs means that they will be much easier to cool than the more powerful models.
