I dont think NV expects 980Ti users to upgrade. They have already stated numerous times that they target and show benches from the previous gen ie; 780 in this case..

Yep. The target is 980 and below. And more focus on below than 980.

No hbm2 for Nvidia 1080ti?

Based on memory bandwidth one the card is a failure! /sarcasm
Why people use that one metric I don't get. Interesting to see if a ddr5x 1080ti would top vega with hbm2. Just to again prove people that it's the whole card and not silly memory bandwidth Ina vacuum that determines performance

Crappy yields. They know a 1080Ti w/ HBM2 would sell faster than HBM2 makers could keep up with, by a huge margin. I still think there may be an HBM2 Pascal Titan, though. Likely for $1200-1500.

So it looks that 8-pin connector isn't an issue with overclocking 1080...

According to Mad Tse, the 8-pin power connector design on reference design is not really a limitation for overclocking. The reference board is using different components than custom designs. MAD points out that reference cards are most likely using locked BIOS. He also mentions that his card was using increased voltage up to 1.3V, which is not possible on reference cards.

While the 2.5 GHz clock he achieved using LN2 cooling is already impressive, it’s not really as important as the clock achieved using air-cooling only. GALAX HOF GTX 1080 is supposedly able to overclock up to 2.2 GHz, without any extreme modifications.

However it is uncertain if NVIDIA approved this card design and its unlocked BIOS, so we don’t know if retail cards will be able to achieve similar frequencies.

Question is if there will be available unofficial unlocked BIOS for reference cards :)

Should I sell my MSI 980ti 6g and get a 1080 ?

The upgrade price would be 180€ for the same brand and cooler type card.

Will the 980ti devalue even more in the commng weeks ?

Pretty sure the resale value of the 980ti will tank once 1070 hits. I would definitely go ahead and do it if all you need to pay for the upgrade is €180.

So throttling, not rendering things properly in games, and fan issues, and a added 100$ makes a lot of sense to me now..........

The throttling only happens if you don't push the power envelope higher or leave fan speeds at stock settings on the FE edition. If you use a custom fan profile you don't throttle. Also the 1080s aren't having any issues rendering things correctly in games. If you are talking about the AoS demo, you have to realize that there will still be driver updates/changes and the fact that it looked better then the amd card whether or not it rendered the snow "correctly" in one demo. The rest of the games benchmarked around the world had zero issues.

So the throttling on the FE only occurs if you use it at stock, or am I missing something?

Correct. If you just drop the card in and leave it alone, you will see some thermal throttling of the boost clock after intensive gpu load because the fan speed doesn't go up high enough to keep it cool.

If you simply use any program, like evga precision, msi afterburner etc, or whatever is currently supported for fan speeds. Up the fan speed to 60,70,80% depending on your ambient/case temps, you won't have the throttling issues at stock speeds.

If you want to overclock as well, you can as long as you push the fan speed and power envelope. These chips get anywhere from 2050 boost clocks to 2.2 boost clocks depending on the silicon lottery.

The FE cards aren't terrible by any means, however the aftermarket cards coming from all of these different companies will have much better cooling and should allow for zero thermal throttling at stock settings. As for overclocking the aftermarkets, we will have to wait and see when they come out, but they will also be able to achieve the same 2 to 2.2 range with the proper cooling and voltage.

Considering no review sites reported the missing snow (and please don't try and spin that as better in any way) what makes you so sure there aren't any other rendering issues. Not that anyone is claiming there is. But you decided to mention it for some reason.

But for review purposes it'll be reported by most sites as not throttling and the noise curve will be worse for those who want to stop the throttling.

Do you think it's the proper way to distribute something that you need to do modifications to make it run as advertised? And then you don't know whether or not the noise is going to be acceptable until after you buy it. Especially when they marketed it as a new and improved high quality cooler that you were paying an extra hundred for?

The card runs as advertised. OCing is a different story. I've yet to see a review where the card failed to hold clocks if not OC'd.

AMD is cheating in the Witcher 3 with Hairworks. Why do you have now a sudden problem with nVidia and Ashes?

It's not really needed. 980 Ti was never memory starved and got pretty much no gains from memory overclocking.

1080 has 10GBps GDDR5X, these chips can easily run up to 14GBps. That means a 1080Ti with 50% more cores will have 40% more memory bandwidth, which is plenty to keep everything running smoothly, especially with the lower clockspeed the 1080 Ti will likely have with the bigger die.

It's well known, reviewers should be aware of this and a single mouse click in the Radeon Settings will turn that behavior off permanently. Not exactly the same if you ask me.

AMD doesnt have the source code for Hairworks, while Nvidia has the one of AOTS (and of TressFX for a nearby HW effect..) , so that s not comparable situations, but i guess that you already knew it...

Source? Or are you talking about limiting tessellation to only render pixels which are actually visible on screen?

Here's my pros and cons of upgrading:

Pros:

-Will have more silent gaming since a 980ti overclocked makes the fan go to 75% which while not that noisy it's still audible.

-Less power consumption vs oced 980ti around 120w difference ?

-Easier to sell 980ti for higher price now than later.

-Overall better DX12 performance.

-New card = 2 years of warranty.

Cons:

-180€ upgrade.

-Not that much increase in performance in DX11 games.

-Might be without a gaming card for a few weeks.

Sooo.. as soon as I find a buyer I accept the deal ? MSI 980Ti Gaming 6G vs MSI 1080 Gaming X

I'm with you. 384-bit 12ghz G5X = 576 gb/s. Screw HBM2. Leave it for the $5,000+ video cards for now. Use it where needed, and save on costs when not.
