Xeon
Introduced in May 2013, Xeon E3-12xx v3 is the first Xeon series based on the Haswell microarchitecture. It uses the new LGA 1150 socket, which was introduced with the desktop Core i5/i7 Haswell processors, incompatible with the LGA 1155 that was used in Xeon E3 and E3 v2. As before, the main difference between the desktop and server versions is added support for ECC memory in the Xeon-branded parts. The main benefit of the new microarchitecture is better power efficiency.
Itanium
Rumors of a successor to Poulson (code named "Kittson") began to circulate in 2012–2013. This was at first associated with a forthcoming 22 nm process shrink, and later revised in the face of declining Itanium sales to a less-ambitious 32 nm node. In April 2015, Intel, although it had not yet confirmed formal specifications, did confirm that it continued to work on the project. Meanwhile, the aggressively multicore Xeon E7 platform displaced Itanium-based solutions in the Intel roadmap.
