No no no. Don't get me wrong here. I SHOULD have been more clear what I
was typing. SGI used RDRAM for texture memory, on their graphics cards.
Intel uses(used?) RDRAM for main memory and not for texture ram on the
graphics boards.
Big difference.

You are right, but countless performance figures shows lacking
performance out of a probably good design thinking. Uhm. Intel + Good
design. Erh...

That is another story.
