3.00 GHz OC Possible on AMD Radeon RX 6900 XT; RX 6800 XT Capped at 2.80 GHz
It's becoming clear that AMD's new "Big Navi" Radeon RX 6800 XT is a treat for overclockers, and that it launched with much lower engine clocks than the silicon is capable of, resulting in what is possibly the largest overclocking headroom on an AMD GPU in a long time. This has been highlighted by recent conquests of the 3DMark Fire Strike leaderboard by RX 6800 XT cards, displacing even the RTX 3090 from the top. It's becoming even more clear now just how far the RX 6800 XT can be pushed. Patrick Schur on Twitter reports that the RX 6800 XT engine clocks are capped at 2.80 GHz, which is possibly why we're yet to see anything faster than that. The upcoming RX 6900 XT, on the other hand, is a better-endowed beast.
According to Schur, the RX 6900 XT has a raised engine clocked limit to 3.00 GHz in comparison to the 2.80 GHz of the RX 6800 XT. This 200 MHz increase, coupled with the 8 additional RDNA2 compute units, should mean that the Fire Strike leaderboards will get another shake-up in December, when these cards are released to market. The memory clock on both cards is capped at 1075 MHz (real), or 17.2 Gbps GDDR6-effective, although this should depend heavily on the overclocking headroom of the memory chips. It's important to note here that neither the 3.00 GHz of the RX 6900 XT, nor the 2.80 GHz for the RX 6800 XT, are advertised clock speeds for the cards, and are achievable only by manual overclocking, in some cases employing extreme cooling solutions such as liquid nitrogen.

Also, this year has been a perfect storm of product release from AMD and hardware utilizing AMD chips, so TSMC can only supply as much as was contracted and all that supply that was contracted has to be divided up between consoles (two major releases), GPUs (6000 series) and CPUs (5000 series). So many hot new products and not enough supply for all that new stuff.
nVidia on the other hand just screwed you by having supply but selling a healthy amount of it to miners. How much hot new hardware did they release? They released the 30 series of GPUs. See above for comparison and see who loves gamers more.
I'm excited to buy new gear, but I can wait and let the I-can't-wait-must-have-now people buy the scalper priced hardware and when prices finally drop to reasonable levels then I can upgrade.
It happened, I've no doubt, just like a lot of Xfx amd card's went to miners.
But step back and both big GPU makers ffd this release up.
Both will happily sell to miners, scalpers whoever buys first and fastest, that's what they're there for, to sell stuff.
As for a 6900 @3Ghz ,do want but can't pay so it doesn't matter to much to me.
Good for the future though.
Not to mention, these cards scale well with the clocks. No wonder AMD had to lock the clocks artificially.
