IRIX (at least circa 6.5, that's the earliest I can remember) was primarily used for graphics. I'm not sure what specifically made the architecture so graphics-friendly (maybe a co-processor daughter board?) but it could render 3d protein fold simulations from PDB files circa 1995 with little difficulty compared to the other gear in his lab. I also remember IRIX being used heavily for CGI in major motion pictures. (I want to say Lightwave or Maya was originally SGI only, due to architectural limitations on every other platform.) AFAIK NeXT didn't even come close to putting out any hardware that came close to allowing that sort of rendering capabilities. Xerox PARC's platform is probably the closest analogue.[1] Basically all of our modern day GUI paradigms are based off of what they did in the late 70s. @pjmlp will jump in with more detail if he sees this.

SGI built in what became OpenGL and had the graphics hardware to pair it with. Later on they added things like the XFS file system (think 9TB volumes in 1994), 64-bit MIPS support, and multi-CPU support. All which were key in allowing SGI to do the things they did with 3D.

  To this day I still have an irrational love for SGI systems. I've been keeping an eye out for a case to use in a modern build just because. SGI also did a lot of pushing of the industry in good directions imho.

    SGI is basically the company that shows amazing engineers cannot overcome psychotic management. From their Windows strategy to their spending, SGI is the pulled defeat from the jaws of victory company.

      I wonder whether it all went wrong when SGI bought Cray Research in '96 or if things were already sliding downhill by then.

        I think in 1995 with the Windows NT strategy marked the end. They were sliding in 96 and had already sold patents to Microsoft by then.

        I think they were just torn between doubling down on their own RISC processors or moving with the times and going Intel. They ended up trying to do both, and that's never going to work.

    Same here. And the colors! those purple shades, wow. I remember seeing my first Indigo machine and being utterly amazed at both the design of the computer, the big ass monitor, the graphical interface (my friend and I just stood there opening and closing the program groups since they had this very cool 3D effect... and of course we were younger so this was super rare for us). Amazing machines. I would love to get my hands on one of them.

      They were great machines, the Indy, the O2, Octane, etc. At the time there was really nothing comparable from a graphics performance perspective. However, even the latest mips SGI machine the tezro gets absolutely spanked by a modern machine in every possible way. They still have a premium price tag, probably due to rarity and legacy software in a few industries, but have poor performance vs alternatives. I'm putting my hope on raptor engineering or another firm delivering a Power based system, the days of the great unix workstation providers are in the past.

  I was only 12 or 13 then but I remember the discontinuity between an AS/400 setup vs SunOS 2.6 (does that sound right for about '98?). But yeah I distinctly remember fighting against the platforms with such frustration (though it helped me a lot in my career so I can't complain too much). Wow, I realized they had a bit of advantage over their competitors but I didn't know their engineers were of that caliber. I knew that SGI made STL, but I had totally forgotten that they standardized OGL as well. Multi-CPU support VAX/VMS style still takes the cake in my book but I remember XFS being absolutely incredible re: latency against ext2 on Linux (2.2?) for small files while running an image host in the early 2000s. Anyways, that makes a lot lot more sense now as to why it'd be the platform of choice. I wish I had a chance to grab that gear before it was decommissioned :( RIP SGI - fond memories.

"I'm not sure what specifically made the architecture so graphics-friendly (maybe a co-processor daughter board?)" It had 64-bit processors, high-bandwidth NUMA links for CPU's/boards, plenty of RAM, interconnects from CPU's to graphics cards that removed obstacles to performance, often custom graphics cards, custom software interfaces, whole-program optimization, and ability to scale up to 256 CPU's and hundreds of gigs of RAM in one image. Compare original Final Fantasy movie to anything 3D animated from that time period to see what SGI Onyx machines could do. ;) Hell, it still looks good despite all the advances since then by gaming and rendering engines: https://www.youtube.com/watch?v=2zQ-LhwYqdQ https://www.youtube.com/watch?v=2zQ-LhwYqdQ That doesn't happen a lot. Quite a bit can be done in real-time on modern systems. A few things in trailer still look better to me than modern games. I recall the detail even included individual strands of hair's physics and rendering. Too bad the plot and acting sucked because it was first to look real enough to fool people passing through the living room. Scared the rural ones, too. Took 32 Onyx2 Machines fully loaded plus tons of custom software. For desktops, Bill Gates and SGI did this demo on a machine with two, 150-200Mhz processors plus their graphics cards: https://youtu.be/zuMSk_S2ARI?t=1m22s https://youtu.be/zuMSk_S2ARI?t=1m22s I start there because the first trick will impress you if you recall what multimedia, graphics, or concurrency were like on Windows PC's in 1998.
