Intel 4 BX80531NK160G User Manual

The Intel

®

 Pentium

®

 4 processor is designed for high-performance desktops and entry level 

workstations. It is binary compatible with previous Intel Architecture processors. The Pentium 4 
processor provides great performance for applications running on advanced operating systems 
such as Windows* 98, Windows ME, Windows 2000 and UNIX*. This is achieved by the Intel

®

 

NetBurst™ micro-architecture which brings a new level of performance for system buyers. The 
Pentium 4 processor extends the power of the Pentium III processor with performance headroom 
for advanced audio and video internet capabilities. Systems based on Pentium 4 processors also 
include the latest features to simplify system management and lower the total cost of ownership 
for large and small business environments. The Pentium 4 processor offers great performance 
for today’s and tomorrow’s applications.
