Much off topic in here there is, Nvidia i see. WoW.

On a side note, have people seen the PureHair performance on Pchardwaregaming's review of Rise of the tombraider? only drops the FPS by 1 - 2 frames

No and it would be welcome. Link please.

Add a 17% memory overclock on top of that.

You can't state the reference one is 1200mhz as The reference 980ti boost clock is not stated. They vary and it could be almost anything, could be 1000mhz for all we know The only figures they give are for the AIB MSI and that is 6% core + 17% memory with an 11% gain.
Can we get off this now for the sake of our sanity?

According to ICDP they clock to 1300 by default, which would make some of these results less than 10% core for 22-36% fps increases, I'm saying 1200 because cards defaulting to 100mhz over stated boost seems pretty usual and makes the %core make some sort of sense to %fps gain (18% core, 22%fps)

If you want to use 1000mhz for the 980ti then it means its overclocking by 50% on the core, so yeah if you want me to change my signature to "Humbug: 980ti's overclock by 50%" well go with your number

If you used the Kingpin for what it is designed for (LN2), you would see a much better clocking card. Running a kingpin on air is fine but if you want 2000Mhz+ clocks, you will need LN2 and this then would be a good overclocking card.

Edit:

And to make it fair, the Fury X also overclocks much better on LN2 with 1450Mhz and 1000Mhz on the memory :cool:

The Kingpins intended purpose is to run fantastic on air not LN2.

This may sound like a crazy statement but it is backed up by the fact it comes with probably the best air cooler on the market.

If it was designed to run fantastic only on LN2 it would either come with a cheap nasty cooler or in just a bare PCB option.

The Kingpin is an example of clever marketing by EVGA.

One would need to use the card in the right capacity to take advantage of the KPEs level of engineering. Also Maxwell as an architecture does not respond well to voltage and as such most if not all cards will hit a limitation around 1500mhz to 1600mhz or not far short of this. In order to push past this the GPU needs to be ran at sub zero temperatures.

This has even been pointed out by Vince multiple times when speaking about the similarity between one GPU to the next. Lower ambient temperatures just aren't enough, this is through no fault of EVGA or the cards engineering. If the proper research is done these types of things (disappointment) can be avoided.

I have no disappointment with my Kingpins, in fact I would say they are the best cards I have ever used.

The reason I bought them is because of the cooler the cards come with as I did not want to run them on water.

Kingpins are not designed for LN2 though as if they were they would come with LN2 pots fitted and not a fantastic (and expensive) air cooler. If EVGA did this though they would not sell many.
 
Seriously if you want to discuss 980ti ocing make a damn sub about it; this is not the place for it......

Tress FX 3 is looking very impressive....curious to what changes AMD will do the AC engine in Polaris
 
It's so hard being Pc gaming enthusiasts, we just have to hope that polaris will keep our chiseled abs and stunning features really really, really really ridiculously good looking.

Polaris should make NVidia look a lot leaner and more chiselled, they are probably going to lose a lot of market share.:D

Anyone with an NVidia card at the moment should be careful what they say on these forums as this time next year they could be using a Polaris based card.:D

I want to be using them THIS year. AMD just give them to me!
 
Funny how the Pascal thread is full of AMD people laughing at woodscrews 2.0 and then this one turned into 5 pages of dredging up old news. For what reason, I can't discern...

AMD won this one, that's all there is to say. Now let's stick to new news and not 980ti OCing or the Fury X.
 
To be honest i think many people will be surprised by this years competition.
People tend to have short memory, and forget that nvidia only had one gpu family which really was in advantage (the advantage is mostly power efficiency, not performance tho) and thats maxwell.
Last year AMD got shafted because 20nm cancellation and HBM delays and shortage, but this year both companies start on equal terms so i think it will be a lot closer than many thinks. Apart from the last gen they were usually pretty evenly matched.

what is polaris 10? a graphics processor for ants! how do we expect people to see the details of lara crofts firm posterior at high frame rates? it needs to be at least three times bigger that this!
 
AMD Polaris specifications
Polaris will use the FinFET manufacturing process, meaning a shrink down to 14nm. This should bring a marked improvement in power efficiency; something that is seen to be a key feature of the Polaris range. As in current high-end Radeon R9 cards, newer Polaris-based models will feature the performance enhancing GCN (Graphics Core Next) architecture, but this time utilising a 4th generation design which boasts features such as a primitive discard accelerator, hardware scheduler, instruction pre-fetch, improved shader efficiency, and memory compression.
Display technologies have also been given some attention, with Polaris supporting capabilities for HDMI 2.0a, DisplayPort 1.3, and 4K h.265 encode/decode.

There is some speculation around how memory will work, as reports have stated that Polaris will incorporate both GDDR5 and High Bandwidth Memory (HBM) products. This led Anandtech to draw the conclusion that the GDDR5 cards would be the lower end, more cost-effective models, with HBM reserved for more demanding use-cases. This makes a good deal of sense, as would a similar theory whereby AMD splits production of the Polaris range across two different fabrication plants, utilising the 14nm process for some and a 16nm for others. These theories, of course, remain highly speculative, but hopefully there will be some clearer definition as the release date draws nearer.
AMD Polaris Release date UK

AMD did recently provide a live demonstration of a new Polaris-based graphics card, where it faced off against an Nvidia GeForce 950 variant, both seated in identical Core i7 systems running Star Wars Battlefront at 1080p on medium settings. Throughout the demonstration the two cards were hooked up to power meters, and the results were interesting. While the Nvidia card returned a respectable average performance/watt rating of 150w, the Polaris clocked a very impressive 88w, illustrating the potential energy efficiency that the next generation brings. It’s early days of course, and we’ll only know the accuracy of these figures when we can do some real world testing of our own, but so far AMD’s Polaris is shaping up very nicely indeed.

Yep and good power efficiency will translate to low heat and faster cards :cool:

The difference in power draw is quite nuts, if it turns out there wasn't any trickery going on.

The 950 is 'officially' rated at 90W, so that would put little Polaris at 28W haha. So there must have been some cherry picking going on.

But hopefully this means, a 2.5x performance/watt increase is realistic in the real world.
