processors deliver high performance with
improved handling protection and socketability
Integrated high performance 16-KB instruction
and 16-KB data, nonblocking, level one cache
256-KB Integrated Full Speed level two cache
allows for low latency on read/store operations
Double Quad Word Wide (256 bit) cache data
bus provides extremely high throughput on
read/store operations.
8-way cache associativity provides improved
cache hit rate on reads/store operations.
Error-correcting code for System Bus data
Enables systems which are scaleable for up to
two processors
The Pentium
®
III processor is designed for high-performance desktops and for workstations and
servers. It is binary compatible with previous Intel Architecture processors. The Pentium III processor
provides great performance for applications running on advanced operating systems such as Windows*
98, Windows NT and UNIX*. 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 Extentions— bringing a new level of performance for systems buyers. The Pentium
III processor is scaleable to two processors in a multiprocessor system and extends the power of the
Pentium
®
II processor with performance headroom for business media, communication and internet
capabilities. Systems based on Pentium III processors 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 offers great performance for today’s and tomorrow’s applications.
