Intel Corporation has introduced two low-voltage 45 nanometer (nm) processors for servers and workstations that run at 50 watts, or just 12.5 watts per core and frequencies as high as 2.50 GigaHertz (GHz).
The Quad-Core Intel Xeon Processor L5400 Series takes advantage of Intel�s 45nm manufacturing capabilities and reinvented transistor formula that combine to boost performance and reduce power consumption in data centres.
Benefiting companies with power-constrained, high-compute density environments, the Quad-Core Intel Xeon L5400 processors are as much as 25 percent faster and have a 50 percent larger cache size than Intel�s previous-generation, low-voltage Quad-Core Intel Xeon processors, while at the same time maintaining the low 50-watt thermal envelope.
The quad-core L5420 and L5410 processors run at 2.50 GHz and 2.33 GHz, respectively, and feature 12 megabytes (MB) of on-die cache and dedicated 1333 MHz front side buses (FSB).
�Using Intel�s hafnium-infused high-k metal gate transistors has allowed our quad-core 45nm low-voltage server chips to attain new heights in power-efficient performance,� said Kirk Skaugen, vice president and general manager of Intel�s Server Platforms Group. �These chips deliver the speed needed while using meager amounts of energy.�
A number of systems vendors are supporting the L5400 series and L5210, including Asus, Dell, Fujitsu, Fujitsu-Siemens, Gigabyte, HP, Hitachi, IBM, Microstar, NEC, Quanta, Rackable, Supermicro, Tyan and Verari.
Next quarter, Intel will also begin shipping a new dual-core low-voltage processor that will boast a 40-watt rating and clock speed of 3 GHz, with a 6 MB cache size and a 1333 MHz FSB. Intel is also extending the existing Quad-Core Intel Xeon processor 5400 series for embedded market segments by offering the Quad-Core Intel Xeon processor L5410 with support for a 7-year life cycle.
The Intel Quad-Core Intel Xeon processor L5420 (2.50GHz 1333MHz 50W ) will cost US$380, while the Intel Quad-Core Intel Xeon processor L5410 (2.33GHz 1333MHz) 50W will be priced at US$320, in 1,000-unit quantities.
