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 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 processors run at 2.50 GHz, and feature a unique 12 megabytes (MB) of on-die cache and dedicated 1333 MHz front side buses (FSB).
This processor upgrade comes with Service Kit.
