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.
