First Intel Haswell Xeon CPUs to be E3-1200 v3 series

Intel's first Haswell-based Xeon server processors will be the E3-1200 v3 series, these chips will be part of the Denlow server platform, which also includes the Lynx Point chipset. The E3-1200 v3 series will receive most of Haswell's new features, including improved CPU and graphics performance, AVX 2.0 instruction set, and the integrated voltage regulator. The onboard dual-channel memory controller will support up to two DDR3/DDR3L modules per channel, with supported frequencies of up to 1600MHz.

Just like the desktop Haswell processors, the server series will use the Socket 1150, which will be compatible with the 2014 "Broadwell" based E3-1200 v4 processors. Most of these chips will be quad-core models with Hyper-Threading support and 8MB L3 cache, but some features depend on the intended market. The workstation parts have 95W TDPs, the server chips have 80W to 95W TDPs, the low-power models range from 15W to 45W and the VHD (Virtual Hosted Desktop) line will range from 65W to 95W.
Xeon processors for workstations will have 95 Watt TDP, and there will be CPUs with and without GT2 graphics. Similar to Bromolow platform, that had Xeon E3-1290 model, which required high efficiency heatsink, Denlow platform will also have at least one 95 Watt CPU, requiring high efficiency heatsink.

Xeon E3 family will include several SKUs for micro-servers and other low-power applications. These include two quad-core processors: one with GT1 graphics and 45 Watt TDP, and another without GPU and with 25 Watt - 30 Watt TDP. There will be also dual-core part with 3 MB L3 cache, and 15 - 20 Watt TDP. This processor will lack integrated GPU.

Lastly, Intel will release a few SKUs for Virtual Hosted Desktop (VHD) applications. These Xeons will be shipped with GT2 graphics, and they will be rated at 65 Watt and 95 Watt TDP.

The Xeon E3-1200 lineup looks mostly similar to E3-1200 v2 with a few exceptions. As much as we can tell, the v2 lineup didn't have workstation model with non-standard heatsink requirements. The E3-1200 v3 also includes new low-power chip with 25W - 30W TDP, and processors for VHD market.
Market Cores/Threads L3 cache Graphics TDP
Server 4 / 8 8 MB GT0 95 Watt
  4 / 8 8 MB GT0 80 Watt
Workstation 4 / 8 8 MB GT0 95 Watt
  4 / 8 8 MB GT2 95 Watt
Low power 4 / 8 8 MB GT1 45 Watt
  4 / 8 8 MB GT0 25 - 30 Watt
  2 / 4 3 MB GT0 15 - 20 Watt
VHD 4 / 8 8 MB GT2 95 Watt
  4 / 8 8 MB GT2 65 Watt
