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.
Sun Fire
Since late 2010, Oracle Corporation no longer uses Sun Fire brand for their current T series SPARC servers, and since mid-2012 for new X series x86-64 machines based on Intel Xeon CPUs. x86-64 server models which had been developed by Sun Microsystems before its acquisition, and were still in production, have all been rebranded as Sun Server X-series.
