It looks like we can expect an AMD APU based on the Zen architecture in the future, though rather interestingly, it will include stacked High-Bandwidth Memory (HBM) with bandwidth speeds of 128GB/s along with a larger onboard GPU for better gaming performance.
This information comes to light from a paper(via: wccftech), which was co-authored by AMD graphics engineer, Mike Mantor. The paper shows that this Zen-based APU would make use of an upgraded version of the memory technology found in Carrizo, which started off as an improved design over the memory interconnects found on the current generation consoles.
On top of that, the Zen APU is shown to use stacked HBM with 128GB/s of bandwidth. Aside from that, we don’t know much more at this time, though earlier reports have suggested that Zen-based APUs won’t arrive until 2017, following the release of desktop Zen CPUs in the fourth quarter of 2016.
As far as the use of HBM goes, we do know that some of next year’s GPUs from both Nvidia (Pascal) and AMD (Arctic Islands) will make use of second generation High-Bandwidth Memory though it looks like this Zen-based APU will be using first generation HBM technology instead.
KitGuru Says: 2016 is going to be a big year for AMD, especially with its new Zen architecture coming out towards the end of the year. Are any of you waiting for AMD to release Zen at the moment?
