Intel prepares three embedded Intel Xeon E5-2400 processors

Next year, Intel plans to launch new Xeon E5 group of families for socket 2011 and socket 1356 Romley platforms. There will be three different subfamilies, aimed at single-, dual- and quad-processor servers, based on socket 2011 platform. Only one subfamily, E5-2400, will be compatible with socket B2 (socket 1356). Microprocessors from Xeon E5-2400 series will be built on Sandy Bridge-EN core, and have from 4 to 8 cores, and from 10 MB to 20 MB of L3 cache. They will support three memory channels, incorporate one QPI link, and work in two-way systems. We already published specifications of Xeon E5-2400 CPUs for server market. One server processor, E5-2430, will be also offered for embedded applications. Additionally, next year Intel will introduce three low-power embedded models for socket B2, Xeon E5-2418L, E5-2428L and E5-2448L.

Intel E5-2418L has 4 CPU cores and 10 MB L3 cache. This microprocessor supports Hyper-Threading, therefore it can process up to 8 threads simultaneously. Clocked at 2 GHz, the E5-2418L features the lowest Thermal Design Power from E5-2400 series, only 50 Watt.

Xeon E5-2428L adds two CPU cores, and has larger 15 MB level 3 cache. Despite of lower 1.8 GHz clock speed, than on the 2418L SKU, its power requirements are a bit higher.

Compared to E5-2418L, Xeon E5-2448L packs twice as many cores and L3 cache memory. This 8-core model runs at 1.8 GHz, and has TDP increased to 70 Watt. Like two other models, it supports Hyper-Threading, Virtualization, and Trusted Execution technologies, and incorporates AES instructions.

At this time, we don't know whether these chips support Turbo Boost feature or not. Known specifications of upcoming embedded Xeons are provided in the table below:

Model	Cores	Threads	Frequency	L3 cache	TDP
Xeon E5-2418L	4	8	2 GHz	10 MB	50 Watt
Xeon E5-2428L	6	12	1.8 GHz	15 MB	60 Watt
Xeon E5-2448L	8	16	1.8 GHz	20 MB	70 Watt
