New Polaris10 and Polaris11 Specifications
AMDs two upcoming GPUs based upon Polaris architecture might see a different configuration, at least that's what tpu claims according to industry sources. AMD would be planning a mainstream and performance-segment GPU which kind off confirms already what we discussed, a R9 470 and 480 was expected initially.
However, TPU writes that the performance-segment chip called "Ellesmere," would feature 32 compute units (CUs), and not the previously suggested 40. Per CU there are 64 shader processors, so that would indicate to be a drop from 2560 shader processors, towards 2048 shader processors. And that's a pretty significant difference.
It is also stated that this product would be able to perform at 5.5 TFLOP/sec for single-precision floating point performance, which is very close to Hawaii/Grenada aka the Radeon R9 390 series. Hawaii uses a lot of power though, a 250W TDP. The new chip would use 150W only, which is good news. it is drawing it's power from one single 8-pin power connector.
Memory wise it is suggested to get GDDR5 memory at 7 Gbps (effective). Obviously some features will be upgraded like support for HVEC/H.265 hardware encode/decode acceleration, DisplayPort 1.3, and HDMI 2.0a outputs.
The lower specced mainstream part called "Baffin" would only get 14 CU x 64 = 896 shader processors, which quite honestly seems to be a too low number and sounds more of an equivalent to the 360 series. This part has a peak single-precision floating-point performance rated at 2.5 TFLOP/s. The TDP is rated at just 50W, and it is expected to feature a 128-bit wide GDDR5 memory interface, holding 4 GB of memory.

That's definitely not happening around the time of 1080/1070 release.
You mean the paper release, the "some hardware" release, or the point where we can all get one if we can afford them? Because all of these points are different. I believe that they will both get widespread availability in the same time frame.
It isn't so bad if it's 390x performance (probably will exceed it in some cases) at 380x prices, with a low power envelope they can use those same GPUs for mobile, a market which they had been outclassed in recent years...
Anyway, Vega will be the GP104 competitor, and we can safely assume it will have ~4096 SPs like fiji, so Polaris' clocks will give us a rough estimate of what we can expect from vega
If the design wins leaks are true, Polaris should have better performance/watt than the Intel Core M GPUs, since Apple will be using them now (Apple went back to integrated the last couple of years because NVIDIA/AMD cards were way too hot for their designs).

I think they would do just fine due to the fact you have alot of people who just dont want to drop 500+ on a video card just to find out a new better one is already on its way and my guess for the reason to not releasing there highend gpu's is due to zen coming soon.

why not DisplayPort 1.4 ?
do DisplayPort 1.3 have 12bit/14 bit color 4k in the AMD card ?
HDR 1000nits or 2000nits ?
AMD have support in WRGB OLED lg ?

There is always a new, better GPU on the way. Always. If you want high-end, you pay a premium and it loses value incredibly quick until it's eventually completely worthless. This is nothing new.

If the 480 can come close to the 390X for around the price of a 380 as a earlier article suggested the card would still be a steal for non 4k users. I do think AMD is making a big mistake for coming out with lower/midrange cards while Nvidia is coming out with 1070/1080's.
