Take it with salt.
But there was also that HBM2 delay rumor, which given HBM1 issues thus far is within the realms of possibilities.
Given potential yields, cost with HBM2, it makes sense to use it only for high-end and stick with current cheaper tech for mid-range and below... that's my thought process on this issue.
Take it with salt.
The latest rumor is that there will be a successor to GDDR5 called GDDR5X, and it will debut with NVIDIA's next-gen GeForce product. GDDR5X will reportedly keep the same 256-bit memory interface we have on the current GTX 980 while ramping up the memory bandwidth to 448GB/sec - higher than the best AMD cards, save the Fiji-based HBM-powered cards. HBM2 is still obviously on the cards, and will include a 4096-bit memory bus at 1GHz with memory bandwidth hovering at 1TB/sec.
In our post about NVIDIA testing its new Pascal GPU internally, I did say "I would love to see a GDDR5-based offering for the cheaper mainstream side, and a HBM2-powered GeForce 1000 series card for the enthusiasts" and it looks like I could be right on the mark if the current rumors are true. It looks like we could expect a GDDR5X-powered, Pascal-based GeForce card while the enthusiast-class cards will enjoy the much faster, but more expensive HBM2 technology.
