Intel Corp. on Monday expanded its family of low-voltage Intel Xeon processors with reduced power consumption aimed at applications that require low amount of heat and minimal sizes.

The new processors are dual-core Xeon LV chips 5128 and 5138 that operate at 1.86GHz and 2.0GHz, respectively, and feature 4MB level-two cache. The exact power consumption of the chips was not clear at press time, though, the previously released Intel Xeon LV 5148 had thermal design power of 40W. The new Intel Xeon 5100-series dual-core processors are intended for 2-way servers.

Intel also announced recently that in the first quarter of 2007 it would launch two more quad-core Xeon processors: a low voltage version for ultra-dense deployments with thermal design power (TDP) of only 50W and a processor designed for single socket workstations and servers.

Separately, Intel unveiled on Monday Intel NetStructure MPCBL0050 single board computer for AdvancedTCA (ATCA) blade server.

The dual-core Intel Xeon processor LV 5138 and LV 5128 will cost $617 and $412, respectively, per 1000 units, and will begin shipping in the fourth quarter of this year.
