Pentium® Processor with Voltage Reduction Technology
INTRODUCTION
The Intel Pentium® processor mobile family provides outstanding performance for all mobile applications. The Pentium processor mobile family consists of the following processors:
· · · · · Pentium processor at 133 MHz Pentium processor at 120 MHz Pentium processor at 100 MHz Pentium processor at 90 MHz Pentium processor at 75 MHz
These Pentium processors are offered in a package developed especially for mobile systems, the Tape Carrier Package (TCP), and incorporate Voltage Reduction Technology and power management SL technology features. Voltage Reduction Technology allows the processor to "talk" to industry standard 3.3 volt components, while its inner core, operating at 2.9 volts, consumes less power to promote a longer battery life. These features allow system manufacturers to offer high-performance, feature-rich notebook computers with extended battery lives. This report provides test results which illustrate the Pentium processor with voltage reduction technology performance on common benchmarks. The results can be used as one of the predictors of performance on real applications that you can expect to see and use on your mobile system. Details of the system configurations are described in Appendix A. Benchmark results are intended to give a standard measure of performance that can be used to suggest how well the application code will execute. However, the measured performance is often the combined characteristics of a given computer architecture and many other tightly coupled system software / hardware components rather than just the CPU. Operating system, compilers, libraries, memory design and I / O subsystem characteristics may well dominate the results.

VOLTAGE REDUCTION TECHNOLOGY
iCOMP® Index Rating
The iCOMP® (Intel COmparative Microprocessor Performance) index provides a simple relative measure of microprocessor performance. It is not a benchmark, but the results from a collection of benchmarks measured on well-designed commercially-available systems. iCOMP ratings are intended to help end users decide which Intel microprocessor best meets their desktop and mobile computing needs. The iCOMP rating is based on the four major aspects of both 16- and 32-bit CPU performance: integer, floating-point, graphics and video performance. The higher the iCOMP rating, the higher the relative performance of the microprocessor.

DOS / Windows Processor Benchmarks
The 32-bit integer Windows performance of the Pentium processor is illustrated by the commonly used Windows benchmarks presented. These benchmarks represent the high performance potential achieved with the mobile Pentium processor for running the immense and expanding base of 32-bit applications without compromising battery life. The 133-MHz Pentium processor offers processor performance gains of up to 60 percent, when compared to the 75-MHz Pentium processor and up to 10 percent when compared to the 120 MHz. Figures 2 and 3 illustrate the Pentium processor performance when executing Norton SI32 and SI16. 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 provided by Symantec. This benchmark was run using Windows 95. SI16 is the 16-bit equivalent and was run using Windows 3.11. For 16-bit and 32-bit application performance potential, the 133-MHz Pentium processor offers performance gains of up to 64 percent when compared to the 75-MHz Pentium processor and up to 10 percent performance gains when compared to the 120-MHz Pentium processor. CPUmark32, illustrated in Figure 4, is a 32-bit Windows processor benchmark provided by Ziff-Davis Labs designed to measure the performance potential for running Figure 5, is the 16-bit equivalent. future 32-bit applications. CPUmark16, shown in Ziff-Davis Lab benchmarks were run using Windows 95.
