OEM and embedded Intel Xeon E5 CPUs are launched

The most important event of this month was introduction of Xeon E5-2600 server microprocessors at CEBIT show. Intel announcement included 17 different models, as well as three E5-1600 series chips for one-socket workstations. Alongside the launch of E5-2600 processors, that was widely covered by hardware news sites, Intel quietly released E5-1603, E5-1607 and E5-2689 models. Also, two new embedded E4-2648L and E5-2658 microprocessors are available now.

We reported on Xeon E5-1603 and E5-1607 SKUs in February. These quad-core processors were spotted in ASRock CPU support lists. According to the lists, the E5-1603 and E5-1607 parts had 2.8 GHz and 3GHz clock speeds, 10 MB L3 cache, and 130 Watt TDP. The specs were confirmed, as well as more details were revealed last week. These Xeons support AES instructions, VT-x/VT-d virtualization and Trusted Execution Technology, but lack Hyper-Threading and Turbo Boost technologies. Official prices of Intel E5-1603 and E5-1607 models are $198 and $244.

Xeon E5-2689 is a new SKU, that was not known before the launch. Despite of its high "2689" processor number, this chip is not as fast as the E5-2690. Xeon E5-2689 has 2.6 GHz base and 3.6 GHz maximum Turbo boost frequencies, which is 300 MHz and 200 MHz slower than on the 2690 model. The CPU has lower 115 Watt TDP, and remaining processor features are identical between 2689 and 2690 SKUs: 20 MB L3 cache, and support for all Sandy Bridge technologies. The official price of the E5-2689 was not disclosed.

Specifications of embedded E5-2648L and E5-2658 were first published last September, and they didn't change since then: 1.8 GHz and 2.1 GHz base frequencies, 8 CPU Hyper-threaded cores, 20 MB L3 cache, and 70 and 95 Watt thermal envelopes. According to Intel ARK database, the processors have 2.1 and 2.4 GHz Turbo Boost speeds, and they support all technologies and instruction set extensions, available in Sandy Bridge. Both parts are priced at $1186.
