A History of Exceptional Technology

The power of the Indigo2 architecture represents a culmination of many technologies. At Silicon Graphics, we have been developing computer systems for the past ten years that easily crunch through large data sets. Our state of the art manufacturing capabilities provide revolutionary solutions at highly competitive prices.

In the past five years alone, we have created seven generations of the Geometry Engine. The Geometry Engine processor now achieves 50 times the performance and occupies one-twentieth the space of the original graphics hardware. This gives you incredible performance for the price of a high-end PC. And finally, our integrated digital media technologies and user environment give you an interactive, highly productive way of working.

Leading desktop compute and graphics performance makes the Indigo2 workstation the fastest application performer in the industry. Indigo2 is the product of the third generation MIPS0 RISC architecture built around the R4400(tm) and R4000(tm) processors running at 150 and 100 MHz, respectively. The CPU and memory bus achieve 400MB/sec and the system I/O bus achieves 267MB/sec throughput. Indigo2 also has the largest cache on the desktop and a standard 64-bit data path which accelerates data at record breaking speeds.

If you need immediate results, this incredible architecture and compute power can be used to move large data sets around, or analyze and compute designs. This combination of tight integration and aggressive design gives you a major price/performance advantage over other architectures. And finally, all this phenomenal power is not loud! Two variable speed fans make Indigo2 one of the quietest systems available.

We've also given Indigo2 unrivaled expandability. So you can choose your configuration. Four industry standard EISA slots or two EISA slots and two high-performance GIO slots are at your disposal. An assortment of industry standard I/O, such as AUI and 10 BaseT Ethernet, as well as two serial ports, a parallel port and five audio connections make Indigo2 comfortable as a stand-alone system or in a networked environment. Compliance with industry standards gives Indigo2 the ability to integrate into a multivendor environment. And Indigo2 can read and write Mac and PC files.
