another Titan or Volta could/would be just that

maybe not 1080Ti though ...

They didn't care about HBMv1 for the same reason no one else did, it was a short stepping stone to HBMv2, where the real performance gains are.

Completely agreed with both points. But I'm simply pointing out to Chev that if nVidia didn't bother with HBM1 even though Fury X had it, they're not going to bother with HBM2 just because Vega has it. Unless Vega rips Titan XP a new one, there will be no HBM2 on Pascal cards save for GP100.

HBM1 was 4GB and way too early

HBM2 in mid-2017 should be very viable .. its better tech and if the time is right by then why not use it ? Especially if the Volta rumor is true

I mean you dont think they will stick to G5(x) for all eternity, right ? Right .. if so, then mid-2017 is as good a time to have a HBM2 flagship as any ...

HBM2...lets see here...

1. Higher bandwidth
2. Less power consumption
3. Smaller footprint

Almost all 3 of these things are on the achievement board for Nvidia and AMD. It'll just be a matter of time before it gets adopted. Maybe another 1-3 generations before HBM becomes mainstream. GDDR5 is on the way out. Probably will be replaced by GDDR5x, then a generation or two after that will be all HBM... I'd say we're still a good 2-3 years out till we see full GPU lineups with HBM. Just IMHO...

They can stick with G5X until they need more than 672 gb/s on 384 bit bus.

This fanboy talk about Nvidia quickly jumping on HBM2 is amusing - they don't need the bandwidth.

HBM2 is most exciting in the APU space - performance will jump exponentially for AMD. This is what gets most excited about the prospects.

I'd imagine all next gen consoles will be an APU with 16GB of HBM2 as well.

I think Pascal is pretty much a done deal this point. Unless they have a backup design for GP102 that incorporates HBM2, there will not any HBM2 based Pascal GPUs besides GP100.

Performance don't jump exponentially due to increased bandwidth.

And I doubt AMD will put HBM2 on their APUs any time soon. Console might be possible, but there are cheaper alternatives.

I'm saying that APUs were held back by the limited bandwidth.

HBM on an APU may be here by next summer.

I don't get the HMB hype at all... More bandwidth is required when bandwidth is a limiting factor. I barely get any gains from Overclocking the memory on my 980ti, HBM is a nice new technology, but it's not like suddenly we will need 4 times more bandwidth specially since GDDR5X exist as a stepping stone. In the end all that matters is performance and cost.
