WHITE PAPER (cont'd) Compaq Professional Workstation - Key Technologies Customer Benefits • Tight integration of the latest technologies to boost system performance • Faster access to data in memory • Support for the latest, fastest Intel Pentium® III Xeon™ and Pentium III processors • Support for the latest and future enhanced 3D graphics controllers with APG Pro • Double the peak bandwidth of the previous AGP 2X with AGP 4X For more information about the 840 chipset, visit the Intel web site at: http://www.intel.com/ 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 − full-speed 256K Level 2, 8-way set associative, 256-bit data bus 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. 6
