Intel Gets Sixteen "Broadwell" Cores to Run at 45W TDP
The latest Intel Xeon D-1571 SoC, designed for high-density data-centers and micro-servers, sets a new benchmark for energy efficiency. If the fact that it's an SoC (a combination of CPU and chipset) wasn't enough, the chip also crams in 16 CPU cores based on the "Broadwell" architecture, with HyperThreading enabling 32 logical CPUs, running at 1.30 GHz clock speed, a dual-channel DDR4 memory controller that supports up to 128 GB ECC DDR4 memory, and 24 MB of shared L3 cache; all at a TDP rated at just 45W. On most high-density server boards, such as the X10SDV-series by Supermicro (pictured below), the chip will cooled by just a small fan-heatsink. Such specs won't come cheap. Server board vendors will buy the Xeon D-1571 at $1,222 a piece in 1000-unit quantities.

I was disappointed to find out that others had tested it and found out that although they had 8 cores they did not perform too great for crunching.
This broader llatta 16 core chip would do better but I would not expect much. The avaton chips were too expensive for me to test, and so are these. That does not change that I want one to play with.
I'm not sure where 16 1.3GHZ cores would fit then. They seem to be targeting the micro server market but I'm trying to think of a usage. Video survellance systems? I can't imagine they need that many cores. NAS? same no need for that many cores. Switches, firewalls? no way they spend that much on the cpu. Maybe something far more specific for military/NASA use?

They do well in scale-out situations like the ones above when compared to the Xeon E3. There's also a bit of gap between the E3 (4c) and E5 (2p 4c-18c) families which this helps fill. Like, when you need E3 level features but E5 number of cores there's the Xeon-D.
Probably not too shabby with VMs as well as they support a number of virtualization technologies. Though I can guess why it didn't make it to Intel's list; they push you to use E5 and E7 because of the massive amount of RAM they can address as well as the performance due to a lot of cores/thread and clock-speed. The Xeon-D can only address up to 128GB which limits it's VM density. So it can do it, but in niche situations.
maybe I'm thinking the wrong kind og virtualization, perhaps this is for containers?
