The next generation Opteron has 32 Zen x86 cores

No APU, 16MB L2, 64MB L3 cache

We recently showed you a new 16 Zen core next generation processor with Greenland integrated graphics and DDR4 support. 

This part definitely sounds interesting but we got an update on the 2016 Opteron server market parts. The next generation Opteron won't have an integrated graphics part but it will have up to 32 Zen x86 cores with 64-thread support. Unlike the highest end compute HSA part that comes with Greenland HBM graphics, the next generation Opteron doesn't have any integrated graphics. The Opteron needs all the silicon space for the L2, L3 cache as well as its Zen x86 cores. 

Just like the 16 Zen core high performance market APU, each core has 512KB of L2 cache and four processors share 8MB L3 cache. The highest end part will come with eight clusters of 4 cores and if you do the math this server oriented CPU will come with 64MB of L2 cache and 16MB of L2 cache for its CPU cores.

A few other notable features for the next generation server parts include a new platform security processor that enables secure boot and crypto coprocessor. The next generation Opteron has eight DDR4 memory channels capable of handling 256GB per channel. The chipset supports PCIe Gen 3 SATA, 4x10GbE Gig Ethernet and Sever controller HUB. Of course, there will be a SMP, dual socket version.

The next generation Opteron will have 32 CPU cores in its highest end iteration, and we expect some Stock Keeping Units (SKUs) with fewer cores than that for inexpensive solutions.

In case AMD comes to market with this part on schedule, and if the Zen core ends up performing as expected, Intel might finally get some competition. Let's just hope for AMD's sake that this server CPU is coming in 2016, sooner rather than later.

We can only on possible Zen-based FX parts for high-end desktops, or the manufacturing process for Zen chips, but at this point we cannot confirm FX parts are coming, and whether or not they will be manufactured in 14nm.
