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.
Oracle Exadata
Oracle Corporation releases a new generation of Exadata every twelve to eighteen months. At each release, Oracle refreshes most hardware components to the latest Intel Xeon processors, memory, disk, flash and networking. The hardware refreshes in themselves result in performance increases with every release. Exadata software is also refreshed with each generation and periodically in between, enhancing some combination of performance, availability, security, management and workload consolidation. In October 2015, features to support the Oracle Cloud were introduced.
