Intel Roadmap Leaks Haswell-E “Lituya Bay” HEDT Platform – Haswell-E and 14nm Skylake Support DDR4


A new Intel roadmap has been leaked by VR-Zone which details Intel's upcoming HEDT and CPU platforms, most notably Haswell-E and Skylake. Earlier, VR-Zone had also reported the upcoming Z97 and H97 chipsets for Broadwell generation of CPUs.

Intel Haswell-E Features DDR4 Memory and LGA 2011 Socket Compatibility

According to the roadmap, Intel would launch their Haswell-E HEDT platform codenamed "Lituya Bay" in first half of 2015. The platform would replace Intel's Ivy Bridge-E "Waimea Bay" platform which is supposed to launch in Q3 this year. Ivy Bridge-E processors would be based on the 22nm process technology and the respective Core i7-4000 series models can be found here. Similarly, Haswell-E chips would be based on the 22nm architecture and remain compatible with LGA 2011 socket however a new chipset would be implemented on the next generation motherboards which would allow for native DDR4 memory support. You heard it right, Haswell-E would be the first HEDT platform by Intel to bring DDR4 memory support.

Intel's Skylake 14nm Chips to Feature DDR4 Support

The leaked roadmap has other key details on it as well such as the Haswell - Lynx Point platform for LGA 1150 socket that launches in June 2013. More details can be found here while their features detailed during IDF 2013 Beijing, China are mentioned here. In  Mid-2014, a year after Haswell's launch this year, Intel would release their Haswell refresh platform, it is clearly not known that if these are Broadwell chips or faster Haswell chips. Little to be known that Broadwell is a kind of a refresh of Intel's Haswell processors on a 14nm die however there's only one CPU platform listed under the 14nm tab on the roadmap and that is Intel's 6th Generation Skylake microarchitecture, there's no exact mention to broadwell at all other than in the previous slide that detailed Z97 and H97 chipsets.

Intel Skylake would be the first consumer platform from Intel to support DDR4 while being based on a new 14nm architecture.It's compatibility with LGA 1150 remains unknown but it would definitely be coming with LGA socketed CPUs, a year before Intel goes all out with BGA packaged 10nm Skymont CPUs.
