Some information has surfaced regarding Intel’s new lineup for Enthusiast grade CPU’s – The Intel Skylake-E processors are supposedly to use LGA 3647 Socket with Six Channel DDR4 Memory.
In recent years, every series of Intel motherboards has supported two generations of CPUs, be it LGA 2011 (X79), LGA 1155, or LGA 1150. It is now expected that with Intel’s upcoming Skylake generation of Xeon and Skylake-E series CPUs that Intel will be moving to a new, larger socket designs and will be upgrading several key parts of their server platform.
Intel’s upcoming Skylake-E socket LGA 3647 will feature 6-channel/Hex-channel DDR4 memory and will feature a larger number of PCI lanes than the previous generation of Intel Xeon CPUs.Right now it is believed that Intel’s Skylake-E Xeon CPUs will feature 48 PCI 3.0 lanes, giving CPUs on this platform the ability to run with more PCI devices like GPUs, ultra-fast storage, and other PCI devices with the hex-channel memory providing the CPU with much more memory bandwidth and support for much higher amounts of onboard memory.
This new CPU socket is huge, with a total of 1636 more pins than Intel’s current 2011-3 platform, making Intel’s Skylake-E CPUs considerably larger than their current Generation Broadwell-E based chips.
