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.

Released in 2007, the Phenom was AMD's highest-end line of processors until the launch of the Phenom II. They were AMD's first processors to be based on the K10 microarchitecture, so they introduced a plethora of new features, including 2 MB of L3 Cache, a faster HyperTransport link, a 128-bit FPU, an integrated memory controller that supports DDR2-1066 (PC2-8500) memory and were manufactured at a 65 nm process for the first time. AMD claims the Phenom X4 to be the first "true" quad-core processor, because it uses a monolithic die design rather than the multi-chip-module design used by the Core 2 Quad and quad-core Core 2 Extreme processors. Suffixes: B=Business class, e=energy efficient, Black Edition=unlocked clock multiplier.
