AMD Details Exascale Heterogenous Processor (EHP) for Supercomputers
AMD published a paper with the IEEE for a new high-density computing device concept, which it calls the Exascale Heterogenous Processor or (EHP). It may be a similar acronym to APU (accelerated processing unit), but is both similar and different to it in many ways, which make it suitable for high-density supercomputing nodes. The EHP is a chip that has quite a bit in common with the recently launched "Fiji" GPU, that drives the company's flagship Radeon R9 Fury X graphics card.
The EHP is a combination of a main die, housing a large number of CPU cores, a large GPGPU unit, and an interposer, which connects the main die to 32 GB of HBM2 memory that's on-package, and is used as both main-memory and memory for the integrated GPGPU unit, without memory partitioning, using hUMA (heterogeneous unified memory access). The CPU component consists of 32 cores likely based on the "Zen" micro-architecture, using eight "Zen" quad-core subunits. There's no word on the CU (compute unit) count of the GPGPU core. The EHP in itself will be highly scalable. AMD hopes to get a working sample of this chip out by 2016-17.

Maybe AMD is planning to do similar for consumer APUs on a new socket?
This looks really really interesting.
Playing Mineswrepper in Windows 10, in DX12m in triple 4k, thats one of the uses i see!
Would luve to upgrade my dual Xeon v3 system to a dual or quad of these ! That might be something worth upgrading to !
Application: HTPCs, next Nintendo console, Steam Machines, and so on.
Also, NASDAQ:AMD appreciated some 20% last week, is there something I don't know about?
Lowend consumer, yes, because just like the Nano coming out, moving memory onto the same die as the GPU and CPU translates to big power savings which can make AMD competitive again for products that need a series GPU (think gaming tablets).
Highend consumer, yes, because it allows a mid-high end system to fit in a much smaller package making it cheaper and more appealing for HTPCs and gaming systems.
Special orders (like Nintendo), yes, because only AMD can offer a package that includes a ridiculously strong GPU with x86 CPU.Markets were generally up the last week and because AMD's stocks are valued so low, that translated to a pretty big jump for them. I don't think AMD said or did anything to cause it themselves.
So next gen of next gen APU is supposed to be like this then?
Firstly this a HPC only design, and secondly this little teaser of an article was lifted from anabstract article published a month ago. The opening sentence carries the salient fact:This is AMD's vision. There are no time frames appended or implied, nor any implication that the design is intended for anything other than HPC deployment. In short, it is AMD's current thinking of what they think will be their future HPC focus.
This news defenetly caught my attention!
I won't have the money to invest, for another week+ so, I am going to have some conversation and do some research with my Broker. Methinks, if I lose a Hundo, oh well. If that hundo grows, bonus.
:cool:
