SGI and IRIX In the '90s, before MacOSX was released, if people were to reffer to a user-friendly Unix that looked cool at the time, that would have been SGI's 64-bit operating system for the MIPS processors, the IRIX. IRIX was first released in 1987, and by 1995 was already a highly respected UNIX, the first with immense multimedia capabilities! Check out our introduction and some screenshots of IRIX.

RE: the reason that SGI machines are so fast is

that it takes a play right out of the Amiga, it has seperate processors for Grafics and sound, the CPUs realy do not do much work other than system stuff. that, and they have large bus bandwidth.

(opens up his case) Hmmm, let's see I have a separate chip for my networking, I have a couple of separate chips on my SB Audigy for my sound, I have a separate GPU on my GeForce4 Ti4600 for my graphics, I have northbridge and southbridge controllers for bus and memory access...

What exactly was it that SGI learned from the Amiga platform that made them so fast again?

SGIs are fast because they are a closed platform that the engineers can tune and tune and tune. PCs are generalized and open, thus ensuring that no hard-core optimizations will be done for fear that they will break something or create an incompatibility.
