Fastest Intel Processor Designed for the Internet

SANTA CLARA, Calif., May 17, 1999 - Intel Corporation today introduced the 550 MHz Intel® Pentium® III processor. The Pentium III processor is designed to power an Internet experience filled with rich audio, video, animations and 3-D that make information come alive. The 550 MHz Pentium III processor is available now in volume and is in systems from several major PC manufacturers, as well as in a boxed format from Intel product dealers and resellers.

"The 550 MHz Pentium III processor enables powerful computers to run the next generation of productivity and media rich applications in modern multitasking operating systems, both on and off the Internet," said Pat Gelsinger, vice president and general manager, Intel Desktop Products Group. "The Pentium III processor's Internet Streaming SIMD Extensions Instruction Set has been a hit with software developers resulting in numerous optimized Web sites and software applications available today."

Performance for Today's and Tomorrow's Applications
For users who interact with the Internet or data-rich applications, the most important advances are the Pentium III processor's high clock speed and its Internet Streaming SIMD Extensions - 70 new instructions that dramatically enhance the performance of advanced imaging, 3-D, streaming audio, video, and speech recognition applications. With all the power needed for the next generation of Internet-enabled software, Pentium III processors will continue to deliver an exceptional experience for PC users well into the future. The Pentium III processor at 550 MHz is 108 percent faster than the Intel Pentium II processor at 450 MHz on CPU intensive 3-D calculations, as shown by Ziff-Davis' 3D WinBench* 99 transform and lighting test. Using Futuremark's MultimediaMark* multimedia performance benchmark, the Pentium III processor at 550 MHz is 53 percent faster than the 450 MHz Pentium II processor.
