If the zen apu with HBM2 comes out...

[Ajay]

I don't understand this thread. HBM still expensive for high priced consumer GPUs. It'll will be a while before HBM would be price competitive for lower end APUs - by then, DDR5 RAM will be out (best guess).

More latency than clock:

Yeah, Kaveri (and later) really did have a screwed-up IMC. Poor thing. Raven Ridge can't come soon enough.

Around DDR3-1800 was the limit for Deneb with Elpida Hyper IC, anything else around DDR3-1866. ~DDR3-1866 for Elpida Hyper on Thuban (CL7, though CL6 at lower speed was faster), DDR3-2000+ CL7/8/9 with PSC, BBSE, or Samsung / Hynix.

On AM3+ I had a couple Bulldozer/Piledriver CPUs that could run DDR3-2133 to DDR3-2400 all day, and two that would not even POST at DDR3-2400 in dual channel.
I had a DDR3-2000 CL6-6-6 CPU-Z validation on Thuban once. Not stable whatsoever...

Fun times

Yup those were the good old days. Phenom II loved that latency too. Mine sure liked Pi Blacks running DDR-1600 CL6. DDR3-2000 CL7 would have been amazing, and 6 . . .

There's no way they aren't working on a zen + hbm APU, its so clearly right where they want to go. Now whether it materializes as an actual product you can buy is another question, since that will depend on the economics of it, not the technical possibility. I'm sure we'll see one eventually, but when is not guaranteed to be any time soon.

If sony+M$ need/want it in the next consoles we will see it...in consoles,if yields are good and they manage to feed the console market the left overs will trickle to the desktop market as well.

But due to costs I doubt it.
