The Intel
®
Pentium
®
III
processor based on 0.13 micron process is designed for high-performance
desktops and for workstations and servers. It is binary compatible with previous Intel Architecture
processors. The Pentium
®
III
processor on 0.13 micron process provides great performance for
applications running on advanced operating systems such as Windows* 98, Windows NT*, Windows*
2000, Windows Me*, Windows XP*, and Linux. This is achieved by integrating the best attributes of
Intel processors—the dynamic execution, Dual Independent Bus architecture plus Intel MMX™
technology and Internet Streaming SIMD Extensions—bringing a new level of performance for systems
buyers. The Pentium
®
III
processor based on 0.13 micron process extends the power of the Pentium
®
III
processor with performance headroom for business media, communication and internet capabilities.
Systems based on Pentium
®
III
processors based on 0.13 micron process also include the latest features
to simplify system management and lower the cost of ownership for large and small business
environments. The Pentium
®
III
processor based on 0.13 micron process offers great performance for
today’s and tomorrow’s applications.
