Intel's next generation Skylake based Xeon V5 server parts have been listed down at Zauba. The engineering samples give us a glimpse at the specifications for Intel's upcoming Xeon processors. Intel recently released their Broadwell based Xeon V4 series and that would be replaced by Skylake based Xeon V5 series in 1H 2017.
Intel Skylake Xeon V5 Processors Revealed - 28 Core Processor Confirmed With 165W TDP
There are a couple of processors listed down over at Zauba. It should also be pointed out that all processors listed on the site are engineering samples and final specifications are expected to change. As for specs, we are starting at 4 cores and going all the way up to the 28 core SKU. Intel Skylake brings a lot of new features to the table and one of those is the latest Purley platform.
ThePurley platformis ascalable and unified platform that would support2S, 4S and 8S chips in the Skylake-EP and Skylake-EN lineup. It will feature the Storm Lake Gen 1 architecture. This is Intel’s next generation Omni-Path interconnect that will befeatured on Purleywhile the Lewisburg PCH will be powering the entire platform. The new fabric can deliver up to 100 GB/s interconnect speed with 56% lower latency compared to the current generation Infini-band Inter connect, allowing up to 48 ports with the new Switch Chip architecture.

Purley platform comes with a range of new features for Intel's Xeon processors.
The new platform also comes with an updated socket. The socket has been upgraded to feature 3647 pins that gives it the LGA 3647 name. The socket is surrounded by 12 DDR4 DIMM slots. This is due to support for next-generation hexa-channel memory and Intel's Optane DIMMs for faster latency solutions.Overall, Purley will be expanding Intel's server platform wit a range of new features.
