 for the CPU to communicate with the floating point accelerator, while the Turbos added a ribbon cable dedicated for this. 60 Hz monitors were used for the 2000 series.

The height of the machines using Motorola CPUs was reached with the IRIS 3000 series (somewhere around 1989, models 3010/3020/3030 and 3110/3115/3120/3130, the 30s both being full-size rack machines). They used the same graphics subsystem and Ethernet as the 2000s, but could also use up to 12 "geometry engines", the first widespread use of hardware graphics accelerators. The standard monitor was a 19" 60 Hz non-interlaced unit with a tilt/swivel base; 19" 30 Hz interlaced and a 15" 60 Hz non-interlaced (with tilt/swivel base) were also available.

The IRIS 3130 and its smaller siblings were impressive for the time, being complete UNIX

 workstations. The 3130 was powerful enough to support a complete 3D animation and rendering package without mainframe support. With large capacity hard drives by standards of the day (two 300 MB drives), streaming tape and Ethernet, it could be the centerpiece of an animation operation.

The line was formally discontinued in 1989, with about 3500 systems shipped of all 2000 and 3000 models combined.

 microprocessors. These machines were more powerful, able to address more memory and came with powerful on-board floating-point capability. As 3D graphics became more popular in television and film during this time, these systems were responsible for establishing much of SGI's reputation.

SGI produced a broad range of MIPS-based workstations and servers during the 1990s, running SGI's version of UNIX System V, now called IRIX

 and RISC architectures in non-embedded computers, SGI announced their intent to phase out MIPS in their systems. Development of new MIPS microprocessors stopped, and the existing R12000 design was extended multiple times until 2003 to provide existing customers more time to migrate to Itanium.

In August 2006, SGI announced the end of production for MIPS/IRIX systems, and by the end of the year MIPS/IRIX products were no longer generally available from SGI.

IRIS GL and OpenGL

). As more features were added over the years, IRIS GL became harder to maintain and more cumbersome to use. In 1992, SGI decided to clean up and reform IRIS GL and made the bold move of allowing the resulting OpenGL

This meant that for the first time, fast, efficient, cross-platform graphics programs could be written.

Name and logo changes

In 1999, in an attempt to clarify their current market position as more than a graphics company, Silicon Graphics Inc. changed its corporate identity to “SGI”, although its legal name was unchanged.

At the same time, SGI announced a new logo consisting of only the letters “sgi” in a proprietary font called “SGI”, created by branding and design consulting firm Landor Associates

, in collaboration with designer Joe Stitzlein. The new logo drew criticism for wasting the professional goodwill associated with the previous cube logo (or "bug"). SGI continued to use the "Silicon Graphics" name for its workstation product line, and later re-adopted the cube logo for some workstation models.

Acquisition of Alias, Wavefront, Cray and Intergraph

In 1995, SGI purchased Alias Research and Wavefront Technologies

Switch to Itanium

In 1998, SGI announced that future generations of its machines would be based not on their own MIPS processors, but the upcoming “super-chip” from Intel, codenamed "Merced" and later called Itanium

, found use only in their own machines.

But this plan quickly went awry. As early as 1999 it was clear the Itanium was going to be delivered very late, and then that it would have nowhere near the performance originally expected. As the production delays increased, MIPS' existing R10000-based machines grew increasingly uncompetitive. Eventually it was forced to introduce faster MIPS processors, the R12000, R14000 and R16000, which were used in a series of models from 2002 until 2006.

SGI's first Itanium-based system was the short-lived SGI 750 workstation, launched in 2001. SGI's MIPS-based systems were not to be superseded until the launch of the Itanium 2-based Altix servers and Prism

The Altix was the most powerful computer in the world in 2006, if a "computer" is defined as a collection of hardware running under a single instance of an operating system. The Altix had 512 Itanium processors running under a single instance of Linux

The first Altix XE systems were relatively low-end machines, but by December 2006 the XE systems were more capable than the Itanium machines by some measures (e.g., power consumption in FLOP/W, density in FLOP/m3, cost/FLOP). The XE1200 and XE1300 servers use a cluster architecture. This is a departure from the pure NUMA architectures of the earlier Itanium and MIPS servers.

in June 2007, SGI announced the Altix ICE 8200, a blade-based Xeon system with up to 512 Xeon cores per rack. An Altix ICE 8200 installed at New Mexico Computing Applications Center (with 14336 processors) ranked at number 3 on the TOP500

Re-emergence

In mid-2005, SGI hired Alix Partners to advise it on returning to profitability and received a new line of credit. SGI announced it was postponing its scheduled annual December stockholders meeting until March 2006. It proposed a reverse stock split to deal with the de-listing from the New York Stock Exchange.

In January 2006, SGI hired Dennis McKenna as its new CEO and chairman of the board of directors. Mr. McKenna succeeded Robert Bishop, who remained vice chairman of the board of directors.

On May 8, 2006, SGI announced that it had filed for Chapter 11 bankruptcy protection for itself and US subsidiaries as part of a plan to reduce debt by $250 million. Two days later, the US Bankruptcy Court approved its first day motions

SGI emerged from bankruptcy protection on October 17, 2006. Its stock symbol at that point, SGID.pk, was canceled, and new stock was issued on the NASDAQ exchange under the symbol SGIC. This new stock was distributed to the company's creditors, and the SGID common stockholders were left with worthless shares.

On April 1, 2009, SGI filed for Chapter 11 again, and announced that it would sell substantially all of its assets to Rackable Systems for $25 million. The sale, ultimately for $42.5 million, was finalized on May 11, 2009; at the same time, Rackable announced their adoption of "Silicon Graphics International" as their global name and brand. The Bankruptcy court scheduled continuing proceedings and hearings for June 3 and 24, 2009, and July 22, 2009.

After the Rackable acquisition, Vizworld magazine published a series of six articles that chronicle the downfall of SGI.
