Yes, it was stated by AMD months ago that Polaris has DP1.3
A lot can happen in months, DP 1.4 was just released, literally in march, is it impossible for AMD to change out the ports for 1.4?
It depends on how the new compression method works, The designs for P10 and P11 were already finalised last year since they have shown working silicon before the finalisation of DP1.4.
If the compression block is updatable with a firmware update then they could claim full DP1.4 without needing to change any hardware. If it means they need to change something in hardware then they will not update to DP 1.4 since it will mean that they need to respin the core design.

How come we have loads of info on the new Nvidia cards and not the AMD cards even though the hype train and rumors have been churning for AMDs for ages?
Not long ago no one had the foggiest idea what Nvidia were doing, now there are confirmed model names and performance figures, where as AMD is supposed to be releasing before Nvidia and theres not a peep from them?

They more than likely have something hidden up their sleeve, showing a certain level of performance and waiting on the competition to show their hand.
Not late at all. Did they EVER post a release date?
Also Nvidia posted absolutely nothing about these cards until yesterday.
The thing is i doubt Pascal was only finalised after DP 1.4 release, IE April, literally weeks ago...
I don't think Polaris is any different in this rearguard to Pascal, Pascal has DP 1.4 because it was compatible, i don't see why the same would not be true for Polaris.
They did exactly the same with Hawaii, Nvidia with the original Titan... nothing from AMD, not a peep. romours were rife of a new card but everyone said "AMD doomed, there is no way AMD can match the Titan on 28nm......" ecte....
Then one day out of the blue the 290X appeared and it beat the Titan. even on a junk cooler.
That same card is still with us today, its actually that good after a couple of tweaks it now competes with the GTX 980. In DX12 with a 980TI

While the physical connection and raw bandwith are the same between DP1.3 and 1.4, 1.4 has a new compression method. And as i said it depends on if AMD's implementation can be upgraded via firmware since the hardware is already set. They have also Said DP 1.3 as the DP version for Polaris.

As i said. with 99.9% certainty Pascal hardware was set a few weeks ago, and yet Nvidia still managed to stick one on, i don't see why that would not be the case with Polaris.
It depends on how Nvidia handle the video outputs and if it is part of the core die or not. They could have even been working DP 1.4 into their design from the start. Just because it was finalised last month does not mean that early implementations were not released. It is no different to how we get draft versions of new Wifi devices. They most likely worked from a draft version of DP1.4 that was just waiting final ratification.
With AMD the video output is part of the core die, which is why they couldn't just upgrade to HDMI2.0 when they refreshed to the 300 series. So it can even depend on how Nvidia implements their display controller and outputs. If the controller does not have the display output hardware embedded and instead uses external logic then it is quicker for them to switch out to newer implementations. But it is more than likely the first case that i mentioned and that they were working from a draft version from the start. The only thing that was changed was the compression method, the underlying connection is still the same as DP1.3.
There's been tons of rumors about Nvidia over the past few months. Many of them entirely correct.
One site obviously had perfectly accurate info back in March:

As Polaris 10 is a mid-tier card is there really any point in putting DP1.4 on them? To be honest I think Nvidia have only done it because it is a bit of one-upmanship and they can say yours is 1.3 ours goes up to 1.4 a la Spinal Tap.
Looking more closely at all this it does seem like the rumours are true about Pascal being a version of Maxwell on 16nm and using brute force to overcome any deficiencies in DX12 or more importantly Async Compute. You will notice that nothing was mentioned about DX12 or Async Compute in Pascal on the show itself.
I believe DP 1.4 will be included in Vega, but not Pascal as it will not be needed for that range of cards.
Bring on AMD Polaris and the benches for Nvidia. Lets get to the real nitty gritty

They have:

How much of a hardware difference is there between 1.3 and 1.4? From a quick search, both still have the same max bandwidth, but 1.4 offering better compression with a couple of extra features.

Well said. DP1.3 is more than enough for such cards. It is vega and big pascal that 1.4 maybe more useful for. By the time they come out, there maybe monitors out that make use of it.
What matters a lot more right now is price and performance. Hurry up AMD, let's get that info out.
Where are those people who said Pascal = Maxwell and doesn't have async in hardware now?
(OK we are yet to actually see it in action).
That is the only difference, A newer compression engine in 1.4, but it still requires a hardware change as it will use a hardware encoder. The only way AMD could support it is if they had implemented the required features in their hardware encoder and only need to activate it with a firmware update. But amd have already claimed Rec2020 capability with their DP1.3 connection, even though Rec2020 is part of the dp1.4 standard.
So based on what Nvidia has shown, here's my prediction for Polaris (based on 14LPP supposedly being better):
Polaris 10XT beats GTX 1070 performance for £300-350
Polaris 10Pro matches/beats GTX980/Nano performance for £200-250
Polaris 11XT matches GTX 970 performance for £120-150
Polaris 10XT beats GTX 1070 performance for £300-350
Polaris 10Pro matches/beats GTX980/Nano performance for £200-250
Polaris 11XT matches GTX 970 performance for £120-150
