Intel prepares Xeon E3-1200 series processors

Earlier today we revealed Intel's plans to release new version of Xeon microprocessor for single-socket workstations. The W3690 is not the only one-way Xeon that we can expect at the beginning of 2011. In the first quarter Intel is going to replace most of Xeon 3400-series CPUs with new E3-1200 series, based on Sandy Bridge microarchitecture. Intel Xeon E3-1200 lineup consists of 11 low- and standard-power microprocessors with core frequencies ranging from 2.2 GHz to 3.5 GHz. All microprocessors from this series feature Turbo Boost technology, as well as Virtualization and Trusted Execution technologies. The specifications of these processors were published by 4gamer.net website, and we decided to post one slide from Intel roadmap as a confirmation of these specs:

The slowest Intel Xeon E3-12xx microprocessor is a low-power E3-1220L. This model operates at 2.2 GHz, includes two CPU cores, but can handle 4 threads at once with the help of integrated Hyperthreading technology, and has impressive 20 Watt Thermal Design Power. Level 3 cache on the 1220L is limited to 3 MB, which is considerably smaller than on other Sandy Bridge Xeons. The second low-power Intel Xeon, E3-1260L, runs at 2.4 GHz, has twice as many cores than the 1220L, and incorporates large 8 MB level 3 cache. This model integrates graphics controller, and has 45 Watt TDP.

Two slowest standard-power models, Xeon E3-1220 and E3-1225, operate at 3.1 GHz, and include 4 cores without HyperThreading support. The E3-1220 has 8 MB L3 cache and it fits 80 Watt thermal envelope. The Xeon E3-1225 has higher power consumption, primarily due to added graphics controller.

Remaining standard power Xeon E3-1200 models are clocked from 3.2 GHz for E3-1230, and up to 3.5 GHz for E3-1280. These microprocessors have 4 cores, and they support HyperThreading technology. Some standard-power Xeon CPUs come in two variations - E3-12x0 without graphics controller, and E3-12x5 with the graphics controller. All these models, including the fastest Xeon E3-1280 at 3.5 GHz, consume no more than 95 Watt on average.
