The Pentium Pro processor family consists of the following processors: • Pentium Pro processor at 200 MHz (256K and 512K L2 cache) • Pentium Pro processor at 180 MHz (256K L2 cache) • Pentium Pro processor at 166 MHz (512K L2 cache) • Pentium Pro processor at 150 MHz (256K L2 cache) This report provides the latest results of benchmarks for the 200 MHz (256K and 512K L2 cache) and 180 MHz (256K L2 cache) on Pentium Pro processor-based systems using the latest Intel 440FX PCIset. Appendix A contains a comparison with the previous chipset, the Intel 450KX PCIset. Details of all system configurations are described in Appendix B. Modern industry standard benchmarks were chosen to accurately demonstrate the superior performance of the Intel Pentium Pro processor family. Processor-intensive benchmarks such as SPECint95* and several 32-bit benchmarks highlight processor performance and as CPU benchmarks are appropriate for comparing processors, application benchmarks are the best method for overall system performance comparisons. Several popular Windows* software applications are used for this purpose. As operating systems and applications have moved towards a 32-bit environment, they require system vendors and users to be cognizant of 32-bit workload performance. As such, most product planning and purchasing decisions are expected to be based on 32-bit benchmarks in order to ensure that these decisions are relevant for the entire life of a system. Intel is committed to using the most robust and relevant benchmarks in characterizing its products’ performance and over time, Intel will adapt this mix as newer benchmarks appear. Robust benchmark programs should be representative of how well the actual applications will execute. However, performance is often the combined characteristics of a given computer architecture and many other tightly coupled system software/hardware constituents rather than just the CPU. Operating system, compilers, libraries, memory design and I/O subsystem characteristics may well dominate the results and make comparisons difficult. This report is intended to show Intel Pentium Pro processor performance on a consistent set of benchmarks . THE INTEL PENTIUM® PRO PROCESSOR The Pentium Pro family of processors is the next generation of Intel's processor technology. Pentium Pro processors are designed for complete compatibility with all existing Intel Architecture-compatible software. The Pentium Pro processor is especially designed to deliver optimal performance for 32-bit software. This includes demanding software like CAD*, 3D*, and multimedia authoring applications running on performance desktops and workstations, as well as large database and enterprise applications on servers. The Pentium Pro processor delivers its superior performance through an innovation called Dynamic Execution. The 200 MHz Pentium Pro processor with internal 512K L2 cache delivers outstanding integer and floating-point performance (See figures 2 and 3): 5 Pentium® Pro Processor Performance Brief • SPECint95 rating is 8.58 • SPECfp95* rating is 6.48 The Pentium Pro processor may contain design defects or errors known as errata. Current characterized errata are available upon request from Intel. PRODUCT FEATURE HIGHLIGHTS • Fully compatible with an entire library of software based on operating systems such as Windows NT*, UNIX SVR4*, SCO UNIX*, OPENSTEP*, Sun Solaris*, and OS/2*, as well as Windows 95*, Windows for Workgroups 3.11*, Windows 3.1*, and DOS*. • Dynamic Execution, which refers to these techniques: − Out-of-order execution − Register renaming − Speculative Execution • Provides support for enhanced data integrity and reliability features: Error Checking and Correction (ECC), Fault Analysis & Recovery, and Functional Redundancy Checking. • Integrated L2 and advanced transaction bus will greatly simplify the design of multiprocessing systems. iCOMP® INDEX ® The iCOMP (Intel Comparative Microprocessor Performance) index provides a simple relative measure of microprocessor performance. It is not a benchmark, but a collection of benchmarks used to calculate an index of relative processor performance intended to help end users decide which Intel microprocessor best meets their desktop computing needs. Intel has updated the iCOMP Index to version 2.0. There are three major market and performance trends that have influenced the latest formula adjustment: 1. The development of benchmarks appropriate for emerging popular application profiles, 2. The accelerating transition to 32-bit operating systems and applications on the desktop. 3. Proliferation of multimedia, communications and 3D. The iCOMP Index 2.0 ratings cannot be compared with the earlier version of iCOMP because different benchmarks are used. The iCOMP Index 2.0 rating is based on the technical categories that encompass three separate aspects of 32-bit CPU performance: integer, floating-point, and multimedia. The multimedia portion is further divided into four components: Audio, Imaging, Video and 3-D (see Intel Media Benchmark section below). Each category and subcategory is weighted based on the estimated percentage of time it enters into the processing picture. The higher the iCOMP rating, the higher the relative performance of the microprocessor. Each processor's iCOMP Index rating is calculated at the time that processor is introduced except that ratings for processors introduced before iCOMP Index 2.0 were calculated when version 2.0 was released. Four standard benchmarks are used for 2.0 (CPUmark32*, Norton SI32*, SPECint95, SPECfp95) as well as the Intel Media Benchmark. Differences in system design (including software) and configuration will affect actual performance. Figure 1 illustrates the iCOMP 2.0 ratings for three Intel microprocessors. The Intel Pentium Pro processor at 200 MHz has an iCOMP 2.0 rating of 220 (iCOMP Index 2.0 was measured only on the 200MHz Pentium Pro processor with the 256KB L2 cache configuration). System 6 Pentium® Pro Processor Performance Brief configurations used in iCOMP Index 2.0 measurements are listed in Appendix B.

(SPEC), a non-profit group of computer vendors, system integrators, universities, research organizations, publishers and consultants throughout the world. It was designed to provide measures of performance for comparing compute-intensive workloads on different computer systems. SPEC CPU95 consists of two suites of benchmarks: CINT95* for measuring and comparing compute-intensive integer performance, and CFP95* for measuring and comparing compute-intensive floating-point performance. The two suites provide component-level benchmarks that measure the performance of the computer’s processor, memory architecture and compiler. SPEC benchmarks are selected from existing application and benchmark source code running across multiple platforms. Each benchmark is tested on different platforms to obtain fair performance results across competing hardware and software systems. SPEC CPU95 is the third major version of the SPEC benchmark suites, which in 1989 became the first widely accepted standard for comparing compute-intensive performance across various architectures. The new release replaces SPEC CPU92*, which has been discontinued by SPEC. Performance results from SPEC CPU95 cannot be compared to those from SPEC CPU92, since new benchmarks have been added and existing ones changed. The CINT95 suite, written in C language, contains eight CPU-intensive integer benchmarks. It is used to measure and calculate the following metrics: • SPECint95 -- The geometric mean of eight normalized ratios (one for each integer benchmark) when compiled with aggressive optimization for each benchmark. • SPECint_base95* -- The geometric mean of eight normalized ratios when compiled with the conservative optimization for each benchmark. The CFP95 suite, written in FORTRAN* language, contains 10 CPU-intensive floating-point benchmarks. It is used to measure and calculate the following metrics: • SPECfp95 -- The geometric mean of 10 normalized ratios (one for each floating-point benchmark) when compiled with aggressive optimization for each benchmark. • SPECfp_base95* -- The geometric mean of 10 normalized ratios when compiled with conservative optimization for each benchmark. Because today's commercial applications are comprised almost exclusively of integer-intensive programs, SPECint95 represents an appropriate instruction mix for commercial applications and is a much more effective benchmark to predict 32-bit business performance than SPECfp95. Figures 2 and 3 show the SPECint95 and SPECfp95 performances of the Pentium Pro processor compared with the fastest Pentium processor. 8 Pentium® Pro Processor Performance Brief SPECint95* Performance Comparison 9.00 8.50 8.00 7.50 7.00 6.50 6.00 5.50 5.00 4.50 4.00 3.50 3.00 2.50 2.00 1.50 1.00 0.50 0.00 8.58 8.58 8.20 8.20 7.28 7.28 5.10 5.10 SPECint95 SPECint_base95* Pentium Processor 200 MHz 430VX 512k L2 Cache Pentium Pro Processor 180 MHz 440FX 256k L2 Cache Pentium Pro Processor 200 MHz 440FX 256k L2 Cache Pentium Pro Processor 200 MHz 440FX 512k L2 Cache ® Figure 2.

These benchmarks represent the high performance potential achieved with the Intel Pentium processor for running 32-bit applications. CPUmark32* is a 32-bit Windows processor benchmark provided by Ziff-Davis Labs designed to measure the performance potential for running future 32-bit applications. Norton SI32* is a new 32-bit Windows 95 benchmark designed to show the speed of a system (CPU, L2 cache, and memory), compared to the speed of other systems for running common 32-bit applications. This benchmark is part of the SYSINFO* module of the Norton Utilities* for Windows 95. SI16* is the 16-bit equivalent. Figures 4 and 5 illustrate the Intel Pentium Pro processor performance when executing these two popular 32-bit benchmarks.

Intel Pentium Pro Processor Performance for the Norton SI32* Benchmark Intel Media Benchmark Multimedia applications are proliferating rapidly. Intel developed the Intel Media Benchmark since an adequate industry standard multimedia benchmark does not currently exist to measure multimedia performance. The Intel Media Benchmark measures the performance of processors running algorithms found in multimedia uses. It incorporates audio and video playback, image processing, wave sample rate conversion, and 3D geometry. The most probable anticipated use of the microprocessor in video applications will be to provide software decompression of video data. One algorithm, which is increasing in popularity, is the industry standard MPEG1 algorithm, such as that used by the popular Xing Technology decompression and the Berkeley MPEG1 shareware software. The video playback component of the Intel Media Benchmark implements the MPEG1 decompression algorithm (ISO11172-2). This benchmark focuses on the contribution of the processor in implementing a video player. The audio component is based on the MPEG1 audio decompression definition (ISO11172-3). This component of the Intel Media Benchmark decompresses and plays a stereo audio clip. The audio component also includes sample rate conversion, special effects and stereo mixing. The image processing component applies digital filters to true-color (24-bit) bitmap images. These filters include a box filter which is used to implement filters such as Gaussian blur and embossing, an image blending function used to combine two images into one, and a color space conversion function used to change an image’s luminance. The 3D component of the Intel Media Benchmark is based on Direct3D* and a geometry routine from the OpenGL* 3D Triangle benchmark. These tests are used to measure the geometry portion of a 3D workload. 12 Pentium® Pro Processor Performance Brief Figure 6 Illustrates the Intel Pentium Benchmark. ® Pro Processor Performance for the Intel Media Intel Media Benchmark Performance Comparison on Windows95* 250.0 196.29 200.0 200.40 176.70 153.27 150.0 100.0 50.0 0.0 Pentium Processor 200 MHz 430VX 512k L2 Cache Pentium Pro Processor 180 MHz 440FX 256k L2 Cache Pentium Pro Processor 200 MHz 440FX 256k L2 Cache Pentium Pro Processor 200 MHz 440FX 512k L2 Cache ® Figure 6.

This second-generation PCIset for Pentium Pro processors delivers world-class performance at an affordable price. The 440FX PCIset optimizes system performance for 32-bit application software in 32-bit operating system environments, and supports Universal Serial Bus (USB) capabilities for Plug and Play connectivity “outside the box.” Intel 450KX/GX PCIset The Intel 450KX/GX PCIsets are targeted to OEMs and motherboard manufacturers designing and manufacturing Pentium Pro processor servers that deliver superior performance and upgradability through multiprocessing. The 450KX/GX are comprised of four components: a PCI Bridge, a Data Path (DP), a Data Controller (DC), and Memory Interface Component (MIC). Options for QFP (Quad Flat Pack) or Ball Grid Array (BGA) packaging are available on the PCI Bridge and the DP. BGA permits OEMs and motherboard manufacturers to use less space in their design and offer greater manufacturing robustness. The 450’s high reliability and scalability is obtained through ECC from the Pentium Pro processor data bus out to memory and parity protection on the Pentium Pro processor address and control bus and all PCI signals. In addition, single-bit error correction is provided thereby avoiding downtime due to this error. Scalability is ensured through upgradable memory of up to 4Gbytes with 4-way interleaving for X-1-1-1 clock data bursts with 450GX. 20 Pentium® Pro Processor Performance Brief Table 3: SYSmark/NT* for Windows NT 3.51*, SYSmark32* Results for the Intel 450KX PCIset Pentium Pro Processor 180 MHz Intel 440FX Dell Dimension Pentium Pro Processor 200 MHz Intel 440FX Dell Dimension Pentium Pro Processor 200 MHz 512k L2 Intel 440FX Dell Dimension Pentium Pro Processor 180 MHz Intel 450KX Hewlett Packard Pentium Pro Processor 200 MHz Intel 450KX Hewlett Packard Pentium Pro Processor 200 MHz 512k L2 Intel 450KX Hewlett Packard SYSmark/NT*/ Windows NT 3.51 602 666 679 601 655 665 Spreadsheet 538 587 613 535 577 604 Project Management 756 838 836 760 833 836 Word Processing 558 622 638 555 600 593 Presentation 639 705 724 635 694 715 CAD 545 606 610 546 603 607 SYSmark32*/ Windows 95 180 197 201 176 191 196 Publishing 164 176 181 162 172 178 Graphics 157 181 177 162 180 180 Presentation 189 207 210 184 201 205 Word Processing 179 193 196 174 186 190 Spreadsheet 191 210 217 187 204 213 Database 159 174 180 156 167 172 SYSmark32*/ Windows NT 3.51 202 221 227 202 220 227 Publishing 244 265 269 245 267 275 Graphics 260 289 269 258 285 293 Presentation 219 242 246 202 219 223 Word Processing 220 239 245 221 241 249 Spreadsheet 164 180 188 178 193 200 Database 194 213 220 191 209 217 SYSmark32*/ Windows NT 4.0 246 268 278 245 265 274 Publishing 299 316 335 299 318 338 Graphics 291 322 332 289 321 331 Presentation 257 280 288 249 271 277 Word Processing 256 276 286 255 275 285 Spreadsheet 226 246 257 228 246 252 Database 230 251 266 232 250 264 System-Level Benchmarks 21 Pentium® Pro Processor Performance Brief APPENDIX B — TEST CONFIGURATIONS UNIX SYSTEM CONFIGURATIONS Processor ® Pentium Pro processor 180 and 200 MHz Pentium Processor 200 MHz System/Chipset Dell Dimension (Intel 440FX) Hewlett Packard (Intel 450KX) Dell Dimension XPS 166S (Intel 430VX) - modified FPU Integrated Integrated Primary Cache 16 KB (8 KB I + 8 KB D) 16 KB (8 KB I + 8KB D) Secondary Cache 256 KB WB / 512 KB WB (200 MHz only) 512 KB WB Memory Size 64 MB EDO (Dell Dimension) 64 MB ECC Fast Page (Hewlett Packard) 64 MB SDRAM Hard Disk Controller Integrated Integrated Hard Disk Quantum Fireball 1080AT E-IDE Quantum Fireball 1080AT EIDE Operating System UnixWare 2.0 UnixWare 2.0 C Compiler Intel C Ref.
