Intel's Haswell architecture based Xeon E3-1200 V3 processor family has been leaked within the Intel server PDF file that was revealed a week ago (via Computerbase).

Intel Xeon E3-1200 V3 "Haswell" 1S Processor Family Revealed

According to the details, Intel's Xeon E3-1200 V3 family is based on the 22nm Haswell architecture is the successor to the Ivy Bridge based Xeon E3-1200 V2 based around single-socketed 1S systems. The Xeon E3-1200 V2 processors are part of the "Denlow" platform and are compatible with the upcoming LGA 1150 workstation boards based on the 8-Series Lynx Point chipset. Their launch is expected in Q2 2013 (June) alongside the launch of Haswell Destkop and mobile processors on 2nd June 2013.

The Xeon E3-1200 V3 processors are almost all quad cores with the exception of the single dual core E3-1220 L V3. The CPUs range from a frequency of 1.6 GHz all the way upto 3.6 GHz on the E3-1285 v3 chip and turbo boost clocks as high as 3.8 GHz all and 4.0 GHz single core frequencies. Each CPUs comes with 8 MB L3 cache while the 1220 L V3 has 4 MB L3 cache. The Xeon E3-1200 V3 parts ship in 84/65/45W TDPs for those chips with either GT2 or GT1 graphics chip and 82/80/25W for those chips with the HD graphics. The E3-1220 L V3 has a rated TDP of 16 W.



Furthermore, the Xeon E3-1200 V3 Haswell processors feature support for DDR-1600 ECC memory, Trusted Execution, Virtualization technologies enabled, AVX 2.0 and TSX instructions. The TDP is a slight bump over Ivy Bridge E3-1200 V2 since the E3-1200 V3 Haswell lineup comes with an Integrated VRM module hence the lesser power phases on motherboards. The Xeon E3-1200 V3 Haswell CPU Lineup is listed below:
