RE[3]: This was obvious trap

I think MIPS had great future. SGI stopped investing in new products while the rest of the world continued race forward and that killed them.
MIPS is actually still going strong in the embedded market. SGI was never really that important for the proliferation of the MIPS architectures since it has found its way in so many high-volume products already in the early 1990s. It is a mature architecture that is also making a bit of a come back in a more visible computing segment. There is renewed interest in MIPS for Android devices and such.
Besides being a widespread architecture, MIPS has two major advantages going for it today:
a) Unlike ARM it has industry-proven mature 64-bit variants for quite some time.
b) It makes _true_ high-performance, low-power computing look easy. Take Ingenic Semiconductor JZ4770 SoC for instance - a 1GHz part drawing 0.25W under 100% CPU _and_ GPU load. Beat that.

Even if they would push high-end MIPS, they would probably at most just match what x86 (that turned out to be the high-perf thing, not Itanium) would soon offer ...and even if ending up somewhat better, then at ridiculous cost; not much point to it.
Now, the times are different, with focus on perf per Watt and lesser dependence on Windows / x86 binary compatibility (still, where MIPS will probably primarily really live on, long-term - Chinese Loongson has hardware-assisted x86 emulation)

There is nothing wrong with a company without their own fab. AMD, Nvidia, VIA... Not to mention ARM.
That was the death of SGI.
I think you forgot about Itanic
Lets be honest. The only real reason they steered away from MIPS was not the problem with MIPS but false promises that Intel was making with their "revolutionary" new architecture (I think latest example of such crap from Intel was larrabee).
R10k was announced as last MIPS chip from SGI, because SGI belived Intel and their fantastic new architecture will deliver great performance. And commodity CPU (used by everyone) would be a lot cheaper than investment in MIPS.
When they realized that Itanium will be very late and very far from promises they quickly released R12k and R14k and some new workstations. But it was too late. PC market was going crazy fast with Moore's law. It had no sense to pay 3-4 (or more) for SGI when you could get similar performance from commodity PC.
I think MIPS had great future. SGI stopped investing in new products while the rest of the world continued race forward and that killed them. There was no problem to take MIPS and make CPU with 3-4 times higher clock (r16k went up to 1GHz).
In addition their management didn't want to bring their technology to PC market. This market was quickly conquered by Nvidia.
