IDT PREVIEWS ROADMAP FOR IDT WINCHIP MICROPROCESSOR FAMILY

Product Development Cycle Targets Growing Value PC Market Segment

PC TECH FORUM, SAN JOSE, Calif., May 19, 1998--IDT (NASDAQ: IDTI) today previewed the new product roadmap for its IDT WinChip ™ family of microprocessors including WinChip 2™, WinChip 2 3D™, WinChip 2+, WinChip 2+NB and WinChip 3. In a presentation at PC Tech Forum, Glenn Henry, senior vice president of IDT and president of Centaur Technology, IDT's design subsidiary, previewed new generations of IDT WinChip microprocessors targeted at delivering the best computing experience for users running business applications and entertainment software on sub-$1,000 desktop and sub-$1,500 notebook computer systems.

"We will continue to execute our core strategy of building simpler, smaller, more powerful microprocessors," said Henry. "This approach also allows us to reduce die size and power consumption, add new features faster and deliver greater performance for Windows®-based business applications.

Sampling of IDT WinChip 2 Commences

IDT also announced today that it has begun sampling its new IDT WinChip 2 and WinChip 2 3D processors for the value desktop and notebook computer market. The IDT WinChip 23D incorporates AMD 3DNow!™ technology which accelerates games and applications written to Microsoft's Direct3D® applications programming interface (API). Based on Winstone® 98 Benchmarks, the IDT WinChip 2 and WinChip 2 3D will offer best-in-class performance vs. other Socket 7 processors running at the same MHz. Samples will initially be available at speeds running as high as 266 MHz, moving to 300 MHz later this year.

Performance gains in the IDT WinChip 2 family have been achieved through core CPU improvements combined with new 0.25-micron process technology, superscalar MMX™ capability, a fully pipelined floating point unit and 100-MHz bus support. The IDT WinChip 2 family will support Super 7™ motherboards, providing all the same benefits as the Pentium II® architecture for uni-processor systems, but at a much lower cost. The release of multiple core logic chip sets with features such as 100-MHz bus and AGP support ensures that users can continue to leverage the cost-effective and established Socket 7 motherboard infrastructure.

Preview of Future IDT WinChip Microprocessors

Future generations of the IDT WinChip family will provide improved performance with a faster core, larger caches, speeds of up to 600 MHz and increasing integration. The IDT WinChip 2+ will combine the IDT WinChip 2 core with a larger primary level (L1) cache to improve performance while retaining a very small die size. The IDT WinChip 2+NB with integrated Northbridge will allow the end customer to select from a variety of Southbridge and graphics performance options. This integration will help lower the overall cost of the PC platform through cost-effective packaging and reduction in motherboard manufacturing costs. The IDT WinChip 3 will introduce a new core and superpipelining techniques to double speeds to between 400 and 600 MHz while maintaining small die size and low cost.

"Our roadmap highlights how far we've come in the last year," said Joe Baranowski, vice president of IDT WinChip sales and marketing. "As the value PC segment continues to diversify, our OEMs will be able to optimize IDT WinChip performance for virtually any user need and price point. Today's announcements reflect our commitment to serving multiple segments of the high-volume value PC segment and to ensuring the Socket 7 infrastructure is maintained as the best solution for uni-processor systems."

About the IDT WinChip Family

The IDT WinChip processor family is optimized to deliver the best computing experience for users running business applications and games on sub-$1,000 desktop and sub-$1,500 notebook computer systems.

IDT introduced the first of its IDT WinChip microprocessors, the IDT WinChip C6 ™ in May 1997. Its small die size and low power are achieved by simplifying the architecture and eliminating or reducing complex logic found in other processors. The microprocessor is offered in a 296- pin Ceramic Pin Grid Array (CPGA) Socket 7-compatible package. The IDT WinChip features performance competitive with other x86 processors, based on benchmarks such as Winstone 97, and runs all leading operating systems, including: Windows 95®, Windows NT®, Windows 3.x, MS-DOS®, Novell® NetWare, OS/2 Warp, Unix®, and Solaris™ as well as other software packages and the latest MMX- enabled multimedia applications.
