Pentium III and Pentium III Xeon Processors
Intel has enhanced the Pentium III and Pentium III Xeon processors to take advantage of the new
Intel 840 chipset. These processors feature 0.18 micron technology and key attributes of the P6
microarchitecture, such as Dynamic Execution, a multi-transactional system bus, Intel MMX
media enhancements, and Streaming SIMD Extensions. The SP750 and AP550 workstations with
the newest processors from Intel are showing industry-leading benchmark performance with
SpecINT_base 95 at 35.6 and SpecFP_base95 at 30.6.

New Processor Features

Support for faster processor speeds: 600EB MHz, 667 MHz, and 733 MHz
Advanced transfer cache
to the Level 2 cache, reduced latency interface to the cache data, and 11.7 GB/s maximum
bandwidth on Level 2 cache transfers at 733 MHz core frequency
Advanced system buffering – six fill buffers providing a 50% increase in concurrent
nonblocking data cache operations, eight bus queue entries allow more outstanding
memory/bus operations, and four writeback buffers that reduce blocking during cache
replacement operations and faster de-allocation times for multiple fill buffer
Support for 133-MHz Front Side Bus (FSB) with a peak bandwidth of 1.07 GB/s
Supports larger memory bandwidth – 1.6 GB/s per memory channel
Customer Benefits
Higher core clock frequency (MHz) performance with 133-MHz FSB and 256-KB full speed
L2 cache provide the power needed to simultaneously run user applications and background
IT services that help reduce network bandwidth requirements and protect corporate data.
Streaming SIMD Extensions provide network bandwidth improvements from enhanced
TCP/IP performance and compression/decompression, as well as an enhanced 3D and
multimedia processing hardware platform. Delivers expanded support for rich data types and
emerging applications and interfaces, such as speech recognition, video and audio.
Improved overall system performance by enhancing the speed at which data is transferred
between the processor and other parts of the system.
Delivers the latest technology with a platform that provides performance headroom and
longevity into the year 2000.
