SILICON GRAPHICS EXTENDS LEAD IN HIGH-PERFORMANCE 3D GRAPHICS

    SILICON GRAPHICS EXTENDS LEAD IN HIGH-PERFORMANCE 3D GRAPHICS
            Brings High-End VGX Technology to Midrange
    MOUNTAIN VIEW, Calif., Nov. 4 /PRNewswire/ -- Silicon Graphics Inc. (NYSE: SGI) today announced a new suite of top-of-the-line systems, the texture-enhanced IRIS POWERVision(TM) BGXT graphics supercomputers for advanced visualization applications.  The company also announced that it will now offer its current high-end POWERVision VGX systems as the midrange of its product line.  With these moves, Silicon Graphics boosts its already unmatched advanced graphics capabilities while bringing its high-end three-dimensional technology to a new level of affordability.
    VGXT graphics supercomputers incorporate graphics technology Silicon Graphics developed for its SkyWriter(TM) host-integrated computer image generator (HI-CIG).  This technology, now available in a compact deskside chassis, gives users a cost-effective platform for running simulation, animation industrial design, and scientific visualization applications that demand high-performance texture- mapping and superior image quality.  With enhancements to Silicon Graphics' VGX graphics architecture, VGXT systems draw textured 3D surfaces up to three times faster than VGX systems.
    "Silicon Graphics' VGXT technology brings unprecedented graphics performance to general-purpose computing systems, combining high- quality image generation with real-time computation," said Thomas Jermoluk, executive vice president of Silicon Graphics.  "These systems open new possibilities for users whose applications require state-of-the-art 3D capabilities previously available only through expensive, specialized hardware."
    VGXT supercomputers include one to eight parallel processors, offering up to 286 MIPS and 70 double-precision MFLOPS of performance. The systems incorporate Silicon Graphics' POWERpath(TM) parallel architecture, based on the MIPS(R) R3000/R3010 RISC processors.  VGXT systems run IRIX(TM) 4.0, Silicon Graphics' enhanced, standards-based version of the UNIX(R) operating system.  IRIX includes the REACT(TM) real-time kernel, which allows the execution of time-critical parallel tasks without burdening the high-performance graphics subsystem.
    Continuing a company tradition, Silicon Graphics will offer VGXT systems at the same prices at which it offered its previous top-of- the-line VGX systems.  In addition, the company has reduced prices on its VGX systems to provide high-end graphics performance and features at midrange price points.  Silicon Graphics introduced its VGX systems in February 1990.
    VGXT systems will be offered both in a compact deskside chassis with up to 4 CPUs, and in a 62" rack with up to 8 CPUs and over 12GB internal disk storage.  Configurations can include up to 256MB of main memory and 100GB of secondary storage.
    Both VGX and VGXT systems provide programmable video output, HDTV support, real-time shading, texture-mapping and anti-aliasing.  VGXT systems begin at $79,900 and will be available for shipment in December 1991.  New pricing brings the entry price for VGX workstations down from $79,900 to $49,900.
    Silicon Graphics Inc. is the leading manufacturer of visual computing systems.  The company delivers three-dimensional graphics, color and real-time technologies to the technical, scientific and creative computing marketplace.  Silicon Graphics Inc. has offices worldwide and headquarters in Mountain View.
