- Here is the press release:
-
- MIPS TECHNOLOGIES ANNOUNCES R4400 64-BIT MICROPROCESSOR
- World's First PC Processor Rated at Over 100 SPECmarks
-
- MOUNTAIN VIEW, California (November 2, 1992) -- MIPS Technologies, Inc. today
- announced the 150 MHz MIPS( R4400* 64-bit microprocessor, the world's first
- processor over 100 SPECmarks designed for PCs, as well as workstations, servers
- and embedded control applications. The R4400 uniquely blends leading-edge CPU
- performance with the critical ability to build affordable desktop systems. The
- new MIPS RISC processor is the only front-running RISC processor supplied by
- multiple commercial sources.
-
- "The MIPS R4400 will allow system manufacturers to deliver stunning RISC
- performance at PC prices," said Robert C. Miller, president and CEO of MIPS
- Technologies. "Desktop applications increasingly demand this kind of power to
- run state-of-the-art operating systems, such as Microsoft Windows NT and UNIX.
- The R4400 processor delivers proven performance today for users who require
- affordable power for their computing needs." The R4400 allows
- high-performance, low-cost system designs optimized for the personal computer
- market place, and is expected to substantially exceed the performance of the PC
- industry's next-generation CISC microprocessor.
-
- "This is a significant event for the Windows NT marketplace," said Paul Maritz,
- Senior Vice President at Microsoft Corp. "Our support of the MIPS RISC
- architecture is an important element of Microsoft's Windows NT strategy. This
- announcement shows that MIPS Technologies continues to deliver the level of
- performance necessary for next generation applications."
-
- The R4400 chip combines strong performance in both integer and floating-point
- calculations with flexible cache memory configurations, making it competitive
- across a wide range of real applications, both commercial and technical.
- Simulation of an R4400 delivers 95 SPECint89 (integer performance), 126
- SPECfp89 (floating-point performance) and 113 SPECmarks overall.
-
- The R4400 microprocessor is a pin-compatible upgrade to the MIPS R4000* and is
- available in three versions: the R4400PC, the R4400SC and the R4400MC. All
- three versions contain 32 kilobytes of on-chip primary cache, and include
- design enhancements for graphics applications. The R4400PC, in the lower cost
- 179-pin PGA (pin grid array) package, is targeted at affordable desktop
- computers and embedded control applications. For highest performance, up to 4
- megabytes of external secondary cache can be directly connected to the R4400SC.
- Such large caches accelerate real-world applications used in the most demanding
- technical and commercial environments. The R4400MC contains additional
- features to enable a range of multiprocessor configurations used in
- high-performance compute and network servers. The R4400 processor operates
- internally at twice the clock speed of the external input clock, and is
- available in clock speeds of 75 MHz external/150 MHz internal, 67/134 MHz and
- 50/100 MHz, in both 3.3V and 5V operating voltages.
-
- The R4400 is the latest addition to the MIPS Technologies line of compatible
- RISC microprocessors. Its predecessors, the MIPS R2000*, R3000(, R6000* and
- R4000, have been shipped in more than 300,000 embedded, desktop, deskside and
- server products. Since its introduction in October 1991, the R4000 processor
- family has delivered leading applications performance, ranking as the highest
- performance single-chip microprocessor for desktop systems. The
- industry-leading processing capacity of MIPS RISC processors enables
- next-generation applications by removing the need for costly additional
- hardware to support features such as graphics processing, and audio and video
- capabilities. By using the power of RISC processors, even entry-level personal
- computers can support the emerging generation of digital media applications.
