Intel has introduced two new quad-core Xeon CPUs, they are 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 new Xeon L5420 runs at 2.5GHz, and the L5410 runs at 2.33GHz, both feature a 12MB cache and a front side bus of 1333MHz. The two new Xeons are expected to compete with AMD’s Opteron Processors.

“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.”

The Intel Quad-Core Intel Xeon processor L5420 2.50GHz 1333MHz 50W is priced at $380 while the Intel Quad-Core Intel Xeon processor L5410 2.33GHz 1333MHz 50W is priced at $320.
