Details of Xeon E3-1200 v3 "Haswell" processors

Another day, another Intel roadmap leak. Last week Intel leaked full product launch schedule, and last weekend Computerbase discovered PDF file, containing recent server roadmap with specifications of Xeon E3-1200 v3 microprocessors. The PDF file since then was taken offline.

Intel Xeon E3 v3 lineup includes 13 microprocessors, clocked as high as 3.6 GHz, and with Thermal Design Power ranging from 16 Watt to 84 Watt. The chips are based on Haswell microarchitecture, and built on 22nm technology. As usually, the family contains standard power quad-core processors with and without integrated graphics. This time though, standard power is defined as 80 Watt - 82 Watt for microprocessors without GPU, and 84 Watt for Xeons with HD P4600 graphics. Higher CPU power consumption is due to addition of on-chip voltage regulator. However, this addition also reduced the number of on-board VRs on the motherboard, and lowered the power, dissipated by the motherboard. Clock frequencies of standard-power processors didn't change from the second generation E3s, starting at 3.1 GHz for the E3-1220 v3, and going up to 3.6 GHz for the E3-1280 v3. All processors support Turbo Boost technology, which for most parts increases clock speed up to 200 MHz for all cores, and up to 400 MHz for 1 core. Only two models, E3-1220 v3 and E3-1225 v3, do not support Hyper-Threading technology.

Low-voltage Xeon E3 CPUs, identified by extra "L" suffix in the model number, also come with and without HD graphics. Unlike mainstream Xeon E3s, TDP of LV parts hasn't changed since E3-1200 v2 generation. Xeon E3-1220L v3 and E3-1230L v3 dual-core parts have 16 Watt and 25 Watt TDP respectively, and they are clocked at 1.6 and 1.8 GHz, that is much lower than their Ivy Bridge counterparts. Our guess that the reduced clock rate was necessary to offset additional power, dissipated by integrated voltage regulator. Remaining Xeon "L" processors have 4 CPU cores. Turbo Boost feature on all LV parts adds up to 300 MHz - 400 MHz for all cores, and 700 MHz - 1.2 GHz for 1 core.

Other standard features of E3 v3 products are 8 MB L3 cache (4 MB on the E3-1220L v3), and support for DDR-1600 ECC memory. The Xeons have Trusted Execution and Virtualization technologies enabled, and they add support for new AVX 2.0 and TSX instructions. The processors fit socket 1150.

Although the E3-1200 v3 SKUs look very similar to v2 generation, there are some differences. The v3 series doesn't have a successor to E3-1290 v2, but it has a new low-power E3-1230L v3 model. Also new in the E3-1200 v3 family are E3-1285 v3 and E3-1285L v3 processors. The E3-1200 v2 generation was supposed to have 1285 v2 and 1285L v2 products, but they were never officially introduced.

Xeon E3-1200 v3 CPUs will be launched from May 27 to June 7. The summary of details of these processors is provided below:

No VT-d, just VT-x?

A reference chart in the leaked roadmap includes VT support, but it doesn't say whether it's for VT-x or VT-d. I believe it is for both, and I updated the specs accordingly, because in other places in the roadmap document it does state "VT-x and -d" support for E3-1200 v3 series.

Any word on sockets or packaging details showing there won't be socketed versions?

All E3-1200 v3 processors will be in socket LGA1150 package.
