Intel’s Skylake platform is set to succeed Broadwell. There have been many leaks in the past that have said Skylake would support PCI-Express 4.0, but according to VR-Zone this is not true. Luckily though the platform will still have DDR4 support.
Skylake is a long way off still so Intel does have time to change their mind on the PCI-Express 4.0 issue. If that happens we will be sure to let you know.
The first Skylake Xeon processor will be the “E3-1200” model. The platform will have 4 DIMM slots and be capable of supporting 64 GB of DDR-2400 MHz memory. Skylake is set to appear in the Greenlow platform which should have the Sunrise Point PCH, which contains the Intel C230 Series chipset. It will have support for up to 20 PCI-E 3.0 lanes, 8 SATA 6GB/s ports and 3 SATA Express ports. Skylake is set to launch sometime in 2015.
