450 MHz to 733 MHz
Datasheet
Product Features
■ Available in 733, 667, 600B, 600EB, and
533B MHz speeds suport a 133 MHz
system bus (‘B’ denotes support for a 133
MHz system bus; ‘E’ denotes support for
Advanced Transfer Cache and Advanced
System Buffering)
■ Available in 700, 650, 600E, 600, 550, 500,
and 450 MHz speeds support a 100 MHz
system bus (‘E’ denotes support for
Advanced Transfer Cache and Advanced
System Buffering)
■ Available in versions that incorporate
256 KB Advanced Transfer Cache (on-die,
full speed Level 2 (L2) cache with Error
Correcting Code (ECC)) or versions that
incorporate a discrete, half-speed, 512 KB
in-package L2 cache with ECC
■ Binary compatible with applications
running on previous members of the Intel
microprocessor line
■ Dynamic execution micro architecture
■ Power Management capabilities

on advanced 32-bit operating systems
■ Single Edge Contact Cartridge (S.E.C.C.)
and S.E.C.C.2 packaging technology; the
S.E.C. cartridges deliver high performance
with improved handling protection and
socketability
■ Integrated high performance 16 KB
instruction and 16 KB data, nonblocking,
level one cache
■ Dual Independent Bus (DIB) architecture
increases bandwidth and performance over
single-bus processors
■ Internet Streaming SIMD Extensions for
enhanced video, sound and 3D
performance
■ Enables systems which are scaleable up to
two processors
■ Error-correcting code for System Bus data
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.
