The latest leak coming from AMD's graphics engineer shows the new AMD Zen-based APU with High Bandwidth Memory (HBM) and a large on-board GPU.



According to a leak spotted in a paper co-authored by AMD's Mike Mantor, AMD is working on a Zen-based APU that will use High Bandwidth Memory (HBM), offering 128GB/s of memory bandwidth, as well as pack a large on-board GPU.

That same paper, spotted by Wccftech.com, shows a couple of interesting things, including a bunch of details for AMD Zen APU interconnect, called Onion3.




The Onion3 interconnect will offer up to 50GB/s of total bandwidth and is an evolution of AMd's Onion3 interconnect used with Carrizo APUs. The same paper also suggest that we will see "stacked memory", or 4-Hi stack of first generation HBM, with 128GB/s of memory bandwidth. It also say that AMD Zen-based APUs will have "more CUs" suggesting that we will see a rather large GPU, packing quite a few Stream Processors.

Earlier last year, we have seen some rumors suggesting that AMD might make a big Zen-based APU with sixteen Zen cores, 32MB of L3 cache, 16GB of HBM, quad-channel DDR4 memory controller and integrated Arctic Islands GPU, which should make a beast of an APU.

Hopefully, AMD will be able to keep up with earlier revealed schedule and we could see such APUs early next year or in best case scenario, even late this year.
