Now now now rbloedow, lets not jump to any drstic conclusions.
Rambus Inc, is a bunch of fraudulent lawyers that are out to line their pockets at any cost, even if it means screwing the consumers.
But I hate nVidia's PR nearly as much....
RDRAM the memory type is actually quite good and has a lot of potentional. The i820 was a disaster...there's not kinder way to put it. That is true and I think even intel employees will acknowledge the i820 is not a good P3 platform. Thus the i815.
But RDRAM in and of itself has lots of potential. DDR-II is supposedly a serial interface. Ultra ATA is being replaced with Serial ATA. USB = Universal Serial Bus, FireWire/IEEE1394 is also serial. For bus design, high speed serial can be very effective if it's done right.
Unfortuantely the P3 is several years old and was designed for a more moderately clocked low-latency parallel bus. It's also designed to have it's FSB synced to the memory bus. The i820 had neither of those properties. It was a high-speed serial asynchronous bus.
The i820 makes RDRAM look bad...and Rambus Inc makes anything they are involved with look bad. But RDRAM still has potential.
