Is everyone forgetting how good RDRAM was, when Intel used it properly?
The lawsuits get tiring, for sure, although I can hardly blame them since they make money from them, and get others to sign licensing agreements, but to comment negatively on Rambus' technology is ill-informed. They have come out with some interesting stuff, and useful products, and still do. There was a time when getting a Pentium 4 without RDRAM was accepting a big loss in performance, compared to DDR. Intel created the i850 and never did anything with it, but it was still the fastest chipset for the Pentium 4 for a long time, despite newer ones from competitors and Intel.
Even for the Pentium III, with the very limited FSB, the i840 was the fastest chipset in dual-processor configurations, by a lot. In single processor setups, the overclocked 440BX could beat it in some. RDRAM wasn't a bad technology, it was just Intel used it too soon (prices were astronomical) and for a processor that couldn't hope to use the bandwidth, and it still performed pretty well.
Don't forget, XDR is used in the PS3, the best selling console in September (I never thought I'd be able to say that

).
Rambus is viewed negatively, and some of it is justified, but it's gotten so extreme it's become exaggerated and uninformed.
