Intel Xeon W CPUs take Skylake Server to workstations
by from Techreport on (#30MF4)
Intel's Skylake-X CPUs put some of the best elements of the company's Xeon CPUs on the enthusiast desktop, but those chips miss out on a couple of features that many would consider mandatory for workstation-class builds. The lack of ECC RAM support from the X299 platform is the most pressing omission, but businesses might also want support for Intel's vPro suite of remote management tools. Some others might also want AVX-512 support with dual AVX-512 FMA units in lower-core-count chips, a feature that's hobbled on lower-end Skylake-X CPUs and missing entirely from Kaby Lake-X chips. Yet another class of user might want more PCIe 3.0 connectivity from the CPU than lower-end Skylake-X CPUs provide.
