Intergraph Corp, which has been plugging away longer and harder at the idea of Intel and NT-based workstations than Compaq, Hewlett-Packard and Digital Equipment Corp, has launched new entry-level personal computers and workstations that it says beats Silicon Graphics Inc’s O2 systems on both price and 3D graphics performance. The Pentium-based TD-20 and Pentium-Pro- based TD 200s are billed as personal computers, while the TD-310, TD-410 and TD-610 are single, dual, and quad Pentium Pro personal workstations, with the TD-610 claimed as the industry’s first quad Pentium Pro workstation. Graphics are handled by Intergraph’s own G76, G95 or Intense 3D add-in cards. Prices for the Pentium based models start at $1,500, while the TD-200, with 3D graphics, has an entry-level price of $2,600, or $5,000 with full 3D graphics capability. And according to Intergraph, the 200 offers twice the graphics performance and more expandability than the Silicon Graphics O2. The machines are intended for entry- level computer-aided design applications such as MicroStation or AutoCAD, web-authoring or Windows applications. The quad processor model is best suited for multi-threaded applications such as Autodesk Inc’s 3D Studio Max. Workstations come with up to 1Gb RAM, Ultra SCSI disk, Ethernet controller, up to ten PCI and ISA expansion slots, eight times CD-ROM, dual-screen support and Windows NT 4.0.
