New in Intel's lineup is the Xeon D, a series of 14nm Broadwell-based SoC server processors designed for blade and high-density server systems. The chip giant prepared two models, a 4-core, eight-threaded version with 2.2GHz core, 2.6GHz Turbo and 6MB cache, as well as a 8-core, sixteen-threaded part with 2GHz core, 2.6GHz Turbo and 12MB cache. Full details at ARS Technica.
. Aside from those core count, cache, and clock speed differences, the processors are the same: two memory channels supporting DDR3 and DDR4, for a total of up to 128GB RAM, 24 lanes of PCIe 3, eight lanes of PCIe 2, two 10gigE controllers, six SATA 3 channels, four USB 3 and four USB 2 ports, all with a power rating of 45W.

The processor cores, memory controllers, and high-speed I/O (Ethernet and PCIe 3) are all on the same die. The slow I/O (USB, PCIe 2, SATA) that would traditionally be in an external south bridge chip are on a separate die housed within the same chip package.
