Intel has introduced two low-voltage 45nm processors for servers and workstations that are designed to run at 50 watts, or just 12,5 watts per core, with frequencies as high as 2,5GHz.<\/p>\n
Aiming to benefit companies with power-constrained, high-compute density environments, the Quad-Core Intel Xeon L5400 processors are said to be as much as 25% faster and to 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 50-watt thermal envelope.<\/p>\n
The quad-core L5420 and L5410 processors run at 2,5GHz and 2,33GHz respectively, and feature 12MB of on-die cache and dedicated 1333MHz front side buses (FSB), the company adds.<\/p>\n
"Using Intel’s hafnium-infused high-k metal gate transistors has allowed our quad-core 45nm low-voltage server chips to this power-efficient performance," says Kirk Skaugen, vice-president and GM of Intel’s Server Platforms Group. "These chips deliver the speed needed while using meagre amounts of energy."<\/p>\n
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.<\/p>\n
