In 1994, IRIX 6.0 added support for the 64-bit MIPS R8000 processor, but is otherwise similar to IRIX 5.2. Later 6.x releases support other members of the MIPS processor family in 64-bit mode. IRIX 6.3 was released for the SGI O2 workstation only. [7] IRIX 6.4 improved multiprocessor scalability for the Octane, Origin 2000, and Onyx2 systems.
The SGI Octane with IMPACT-class graphics was first supported by IRIX version 6.4. VPro-class graphics have been supported since IRIX version 6.5.10 for V6 and V8, with V10 and V12 graphics supported as of 6.5.11 (or 6.5.10 with a special driver patch). Linux and OpenBSD have had support.

The Indigo Magic Desktop was renamed to IRIX Interactive Desktop with the release of IRIX 6.5 in 1998. Beginning in 2000, Eric Masson, a passionate user of SGI systems, began work on a recreation of IRIX Interactive Desktop for Linux .
Indy was launched with the IRIX 5.1 operating system, [1] by which it is binary-compatible across the entire SGI family. [1] [3] 5.1 does not take full advantage of the hardware due to inadequate memory management. Later in 1993, SGI increased the base specification to 32 MB. IRIX 5.2 and later have much more efficient memory usage. [3]
IRIX® 6.5 offers system scalability and binary compatibility across the MIPS® processor-based family of platforms and is compliant with UNIX® System V Release 4 and The Open Group's many standards, including UNIX 95 and POSIX®.
These systems ran the IRIX 6.5 Advanced Server Environment operating system. Entry-level variants of these systems based on the same architecture but with a different hardware implementation are known as the Origin 300 and Onyx 300.
The RealityEngine2 is the original high-end graphics subsystem for the Onyx and was found in two different versions: deskside and rack. The deskside model has one GE10 (Geometry Engine) board with 12 Intel i860XP processors, up to four RM4 or RM5 (Raster Manager) boards, and a DG2 (Display Generator) board. [4]
