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.

    I like it because it agrees with my personal mindset about understanding technical detail; and I only have a popular science level notion of the philosophy involved, so it works quite well for me. Probably if I knew more philosophy I would dislike it, in the same way that I dislike popular science because I know too much science so that it is boring.
