SUN ANNOUNCES 450 MHz and 400 MHz UltraSPARC-II MICROPROCESSORS

Processor-of-Choice for Workstations and Servers Boosts Speed by as Much as 25 Percent

SAN JOSE, Calif. - Nov. 2, 1998 - Sun Microsystems, Inc. today announced the availability of samples of the 400 MHz version of the UltraSPARC^TM-II microprocessor and the plans for the 450 MHz version to be available in the Spring of 1999. The new processors are proof of Sun's commitment to its recently announced microprocessor roadmap - a roadmap taking the UltraSPARC microprocessor architecture into the next century.

Sun's ability to continually deliver higher performance processors with industry-leading bandwidth that enables higher system throughput while maintaining binary compatibility has made the UltraSPARC architecture the leading choice for the server and workstation markets. This is demonstrated in recent reports from independent market research which indicate that Sun leads the market in workstation and servers shipments. (See Sun Microsystems' announcements from October 12 and September 15)

"Sun is the leader in the workstation and server markets. Our UltraSPARC processors deliver a high level of performance, great throughput, as well as scale from one- to 64-way," said Marge Breya, vice president of marketing, Sun Microsystems, Microelectronics. "UltraSPARC is the processor-of-choice for server and workstation customers. Our recently announced microprocessor roadmap that takes the UltraSPARC architecture up to 1.5 gigahertz demonstrates our intention to continually deliver performance improvements that will keep Sun at the forefront of these markets."

Process Improvements Lead to Greater Performance

The performance boost to the 450 MHz and 400 MHz UltraSPARC-II chips is achieved by moving the design into Texas Instruments' 0.25 micron process technology.

The UltraSPARC-II microprocessor family now spans from 250 MHz to 450 MHz. An UltraSPARC-II microprocessor, running at 450 MHz with 4 Mbytes of Level 2 cache is estimated to deliver a SPECint95 rating of 19.6 and a SPECfp95 rating of 27.1.

UltraSPARC processors are the first line of chips to support the recently announced fully 64-bit Solaris^TM 7 operating environment. As a result, users don't have to wait to take full advantage of the performance, reliability and scalability delivered via the combination of a 64-bit operating system matched with a 64-bit processor.

Availability and Pricing

Samples of the 400 MHz version of the UltraSPARC-II microprocessor are available today in a 4 Mbyte Level 2 cache configuration. When available in volume, the UltraSPARC-II processor at 400 MHz is expected to sell for $4,249 in 1,000 unit quantities. Pricing for the 450 MHz version will be announced when it is available in the Spring of 1999.
