Intel today increased its energy-efficient performance lead with the introduction of 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 2.50GHz.
The Quad-Core Intel Xeon Processor L5400 series takes advantage of Intel’s unique 45nm manufacturing capabilities and reinvented transistor formula that combine to boost performance and reduce power consumption in data centers.
Benefiting companies with power-constrained, high-compute density environments, the Quad-Core Intel Xeon L5400 processors are as much as 25% faster and have a 50% 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 2.50GHz and 2.33GHz, respectively, and feature a unique 12Mb of on-die cache and dedicated 1333MHz 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,” says Kirk Skaugen, vice-president and GM 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 3GHz, with a 6MB cache size and a 1333MHz FS
