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.

I still think nVidia has\had some one on the inside to even give so much performance on their card never mind the lesser pricing.
Yep thats going make them sell out hell fast.
Sorry not buying the scalper things is the whole blame here or even close, although it's not helping.
Nvidia just being reported selling 3000 series card to miner directly, so there are less card floating around the retail market
Searching "nvidia direct sales to ethereum miners" will result multiple posts referring to Nvidia's own Q3 earnings report
3Ghz limit is amazing. We're not so long away that your GPU ticks faster then your CPU does.
Could it be that the infinity cache become unstable at high clocks ?
Perhaps there's a indept on how that cache actually works and how the speeds are linked.
There were some rumors around PS5 APU about these becoming unstable in a bit of a weird way at high clocks, maybe that is similar.Red Devil is pretty much extreme cooling already :D
What he is doing is extreme overclocking. Hardware mods and all. Besides, 2.75GHz was not exactly stable even in the test he was using. IIRC he eventually backed off to 2.7GHz for more stability.The only think in Q3 report was that Nvidia sold cards to mining for $175M instead of the expected $150M. An analyst concluded this must be Ampere cards sold to miners. Since Nvidia has not and will not clarify this much further we probably won't know the exact spread on what was sold. For what we know, they could as well be clearing old stock.
You can't cure stupidHardware? A 'terminal' is enough. Some low spec mobile phone, like an Apple or Android device. Note that I'm saying device. They all want you to hook in on that cloud. MS is trying it too, and Azure is taking it pretty far already if you see how its used in enterprise.
You're not even paying for software. You don't even own a license. You get a login, and zero rights, no control, and everything is fluid and subject to change. Cyberpunk already released years ago and we're playing it ;)
1. If a company has a strong position with its product, it can create an initial short supply of it and raise the price.
2. Once the new pricing is established, they slowly ramp up supply. If done right, one ends up with a higher margin without losing any meaningful amount of potential sales.
3. ???
4. Profit!

It certainly shows the potential for future cards! Guess the next 2 years look very promising. :D
