Fudzilla have 'obtained' a slide showing details of a forthcoming APU from AMD based on their new "Zen" architecture.
The highest end compute HSA part has up to 16 Zen x86 cores and supports 32 threads, or two threads per core. This is something we saw on Intel architectures for a while, and it seems to be working just fine. This will be the first exciting processor from the house of AMD in the server / HSA market in years, and in case AMD delivers it on time it might be a big break for the company.
Each Zen core gets 512 KB of L2 cache and each cluster or four Zen cores is sharing 8MB L3 cache. In case we are talking about a 16-core, 32-thread next generation Zen based x86 processor, the total amount of L2 cache gets to a whopping 8MB, backed by 32MB of L3 cache.
This new APU also comes with the Greenland Graphics and Multimedia Engine that comes with HBM memory on the side. The specs we saw indicate that there can be up to 16GB of HBM memory with 512GB/s speed packed on the interposer. This is definitely a lot of memory for an APU GPU, and it also comes with 1/2 rate double precision compute, enhanced ECC and RAS and HSA support.
The new APU sports quad-channel DDR4 support, with up to 256GB per channel at speeds of up to 3.2GHz. No information yet on which processor socket this APU will use, but it's safe to assume the DDR4 support alone will render it incompatible with all AMD's current motherboards. Support is also included for secure boot and AMD's encryption co-processor.

Ugh. Anandtech is a bunch of amateur hobbyists. The problem with sites like that and (and tom's etc) are that they do not know what they do not know. That's the curse of being a self-educated hobbyist, you learn by exploration but without a guide you have no idea what might be around the corner. That's not to say that professionals can't be ignorant, just that is so much easier for a hobbyist to fool themselves into thinking they understand the elephant when all they've seen is the trunk.

No, that's the curse of being poorly educated, which many college and university graduates suffer from as well. Sure, if you only talk about the ones at the top, you can make them seem like elites, but in that case, people who self-educate properly also know what they're doing. Don't lump all self-educated people together in the same group; it can be done poorly, and it can be done well. In fact, the best people in colleges and universities all self-educate, because if they just mindlessly took in information, they wouldn't understand a thing.
In the Age of Information, it's more possible than ever to self-educate. The lazy make up excuses for not doing so, and the intellectually lazy look at these lazy people and blame the very idea of self-education for the failings of specific individuals.

Hah! It's the AC with a degree persecution complex.
You'll note I said nothing about being degreed and everything about being a professional.

Seriously though, everyone's an individual - you can't realistically lump people into boxes and hope to be correct about it. There are amateurs who really really know their stuff, and there are professionals you wonder how they ever got even their toe in the door.

The fact that there are edge cases is not particularly meaningful when talking about generalities.
