Another article suggest NV's Pascal is due in the 2nd half of 2016, with validation of Pascal to be done in this first half. Samsung will be supplying them with HBM2 chips.
Looks like SK Hynix is supplying AMD, hence the exclusive rumor awhile back.
ST Micro is doing HMC (for Intel?).

The source is a Korean tech news, they have discussions with folks in Samsung to get the article with quoted sources from those in the industry.
This suggests NV is at least 1 quarter behind AMD, if AMD's plans to launch in Q2 isn't delayed.
Here's the interesting part, since the mid-range chip is unlikely to use HBM2, it means NV will be having a big Pascal w/ HBM2 sometime in 2H 2016. Likely Tesla, but maybe consumer Titan class!
IF AMD only has 2 Polaris in 2016, small and mid-range, they got nothing to compete with big Pascal. >
This is potentially a major blow to AMD if NV release consumer Pascal Titan in late 2016, it's the perception, NV is supreme leader in graphics that will be very damaging. <
IMO, if AMD isn't working on a big Polaris for 2016 release, they will be in a world of hurt.
