45NM QUAD-CORE

INTEL® XEON® 5400

SERIES PROCESSORS:

Featuring the Revolutionary 45nm

enhanced Intel® Core™ microarchitecture

45nm technology is expected to fuel ongo-

ing performance advantages for years to

come. It significantly increases transistor

density over previous-generation Intel

65nm technology.

45nm Intel Xeon processor 5400 series:

820 million transistors

Previous-generation Intel® Xeon®

processor 5300 series:

582 million

transistors

More transistors means more capability,

performance and energy efficiency from

enhancements that include expanded pow-

er management capabilities, enhancements

designed to reduce virtualization overhead

and 47 new Intel® SSE4 instructions which

can help improve the performance of

media and HPC applications.
