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.
