I guess I could copy my post from a different forum to here.
Is 2300 mhz a pipe dream? Lets just take a look at TSCM 16FF+ technology.

TSMC's 16FF+ (FinFET Plus) technology can provide above 65 percent higher speed, around 2 times the density, or 70 percent less power than its 28HPM technology. Comparing with 20SoC technology, 16FF+ provides extra 40% higher speed and 60% power saving. By leveraging the experience of 20SoC technology, TSMC 16FF+ shares the same metal backend process in order to quickly improve yield and demonstrate process maturity for time-to-market value.
Now remember this is being applied to the 980 based process. Looking at the power of the 1080 it appears Nvidia went only with performance and no power savings. You can see this in the charts from Tech power up looking at 1080 and 980 typical game consumption.

Since they claim above 65% higher speed and we see that they did not try for reduced power lets use 70%. A typical 980 has a base clock of 1126 mhz with an ASUS strix card having a 1240 mhz clock.

So lets do the math 70% of 1240 is 868 mhz which equals 2104 for max frequency. at same power as a ASUS Strix which is 190 w. The Strix can OC to 1481 so add 168 more to 2104 and you get 2272 mhz. This is a best case scenario with TDP moving into the > than 200 watt area. The problem then becomes temperature of the chip and would cause the card to throttle just as we are seeing with the reference 1080 only averaging a 1778 mhz clock frequency in games after 20 mins. Nvidia showed us a clock of 2141 mhz during their launch, do you think if they could have gone a lot higher they would not have displayed that capability?

The maximum achievable 1,886 MHz, the GeForce GTX 1080 Founders Edition are more of a theoretical value: In games you never see this clock. There, the highest ever measured frequency was during the tests 1,835 MHz, but was also the clock after a few seconds history. In demanding titles 1.785 MHz has finally placed as the highest, realistic clock out.
I would hope that now since everyone has had a day to become more objective the hype train would slow down. Don't misunderstand my point of this card, it is a good product and is clear that Nvidia went for max performance. The problem I have is a 980TI is only 13% slower and the price of a 1080 ASUS Strix will not be less than $700.
