''The 1080 hits its temperature target by dropping the GPU's clock rate. During a gaming loop, it falls all the way down to its base frequency...although we haven’t seen any partner boards yet, it’s probable that third-party coolers will give enthusiasts access to even more headroom, just as we’ve seen in generations past''
http://www.tomshardware.com/reviews/nvidia-geforce-gtx-1080-pascal,4572-11.html

But that article shows:
03-Temperatures_w_600.png


Where the default profile seems to take the 1080 into the temperature limit, but with the fan at 100% the temps are kept under 70 degrees.

Those are painful, fan turned way up it's not bad but at stock it doesn't even sustain above the base clock.

We will see, right now its sub 2.1Ghz and throttles to way below that once warmed up.
And...

So it not the temperature.

Until we see good overclocks that also hold them it is what it is... but but but nothing. we don't even know yet if the GPU is capable of running 2.5Ghz.

It is temp, it wouldn't be power, though temps can increase power, just not that much. You can't run at 2.1Ghz be then be throttled by power and end up down at 1.6Ghz, the tomshardware shows the direct link from temp to power. From stock it drops significantly from 1850Mhz to 1600Mhz on a prolonged run, overclock and whack the fan to 100% and they can hit over 2100Mhz but that still throttles over time due to temp. If it was power then the stock run wouldn't go from 1850-1600Mhz as temps went up.

But stock running with a quiet fan Tom is saying this card doesn't even stick above the base clock for prolonged gaming. Again stock fan setting and it's down to 50Mhz above the base clock within 5 minutes of gaming. Worse than that really is, if a founders edition while running quietly won't do much above the base clock, then the better cooled AIB cards that might end up 400-500Mhz faster sustained while still quite, then they won't be at all cheaper.

Tom mentioned in the stream that the highest they've seen on the FE cooler so far is 2.2GHz which matches up with my expectation - might get some cherry picked cards that manage a couple of hundred MHz more on decent aftermarket coolers/boards.

The FE seems to hold 2GHz fairly well if you ramp the fan up just not on the stock profile and you hit the power limit much above that - which gives some hope for AIB offerings.

Whose Tom and what does he do?

You don't think every reviewer has cherry picked cards?
 
You know that nVidia guy that Tom.

Not saying every card will run like that - just a hard upper limit on what nVidia has seen so far over a range of cards.
 
I think it's worth pointing out the Tom's Hardware review thinks:
''It offers a substantial step up from GM204 and an impressive boost compared to the former flagship GeForce GTX 980 Ti. In fact, across the eight real-world games we benchmarked today, GeForce GTX 1080 averages 34%-higher frame rates than the 980 Ti at 3840x2160.''

Hard to know because the reviews do not give detailed enough info on anything except stock / default results.

Pretty surprised they've disabled 25% of the chip for the 1070. Almost makes you think they don't want it to be too close to the 1080 :P

Also, that being the case, it means the 1070 is effectively a few mm2 smaller than Polaris 10XT.

It'd be quite interesting if AMD can get in between the 1070 and 1080.
 
after read lot of reviews, I will preorder 1080 when it available . the the full fat Ti/Titan at best will be end of the year or next year anyway so i will enjoy this card till then .

exactly what am thinking...AMD have the ability to poop all over the 1070 launch, if they didnt screw up polaris this should be good.
polaris 10 pro 390x perf for 300$, and polaris 10 XT 400$ with 1070 performance.

That's why you wait for the custom cooling models.

Not really a fair comparison comparing custom cooled 980ti's to reference 1080's.

I don't think any reference model 980ti would hold a 1500mhz overclock either.

Software is an issue with overclocking on Pascal as well, once that is figured out things should be slightly better.

Dont worry, Polaris will certainly be a solid chip so dont worry about that. Its the PR and marketing department you should be worried about and the at times lack of initiative that AMD have. But hardware wise im 90% confident that Polaris will battle well within whatever bracket it fits.

u have the amd belief bug? :cool:
 
So after look ing at almost every review

980SLI VS 1080
1080 best case 200%
1080 worst case -11%

Now all reviews I found used AIB COOLERS or water cooling 980's not a fair comparison at all

After 1080 AIB comes out I reacon 980s will die :)

Plus people seem to forget driver updates two weeks after launch I remember 20% gains from driver tweaks in certain games of course
 
Drivers are key. They will squeeze a lot of performance out I feel.

However, I've decided to keep my 980s until we have the 'full fat' Pascal. I don't really gain anything from SLI 980 to single 1080 except for single figure percent, and maybe less risk of scaling issues.

Mine hold 1500 :). Well 1506 at a push. Reference EVGA SC. watercooled though.

I do agree though generally custom cards will perform better and not have such issues with thermals.
