The chip giant claims Purley is its biggest update since Nehalem, the new platform promises better performance/Watt and introduces the 100Gbps Omnipath interconnect, six-channel DDR4 support, and the new AVX 512 instruction set.
Intel will be unleashing its new Omnipath Architecture inside of the new Skylake-powered Xeon processors, something it calls Storm Lake (Generation 1). This new PCH will be codenamed Lewisburg, where it will include updated Ethernet controllers. The Skylake Purley update will also pave the way for Socket P, with a TDP that's configurable between 45W and 165W. The PCIe slots will have 48 lanes of bandwidth to play with, but this could change at any time.
