If the 820 launch had not been screwed up by Intel (not Rambus)

That's your opinion. What I heard is that the interface specs provided to Intel by Rambus on the high frequency characteristics requirements were woeful. Results: GIGO: Garbage in- garbage out. Of course, Intel could have scrutinized those specs better. You're talking about data rates not used before on a computer board. Intel should not have assumed textbook quality waveforms without treating the thing with a transmission line design methodology. Anyway, both sides were guilty.

elly,

RE:"If the 820 launch had not been screwed up by Intel (not Rambus) the sales of the 820 would IMO been much higher.
The 820 is a good platform but it could have been much better."

If Intel couldn't do it nobody could. Perhaps rather than patent and litigate, Rambus should have cooperated a bit more with Intel or at least tell Intel how it really was, if they even knew. Apparently Rambus memory leaves very little tolerance.

RE:"We will have to see how well the P4 with RDRAM performs. As you know, it is the first processor designed to actually be able to use the bandwidth delivered by RDRAM."

Two problems...
1. We already have an idea how the Pentium 4 w/Rambus performs and it's best attribute right now is Mhz. Not Rambus, not IPC.

2. Since the P4 was designed for Rambus, at the very least it will have to be tweaked to run with DDR SDRAM or plain 'ole SDRAM. Given the record of trying to get stuff designed for RDRAM to run on other types of memory, this may not be a cakewalk. You think Intel people are mad now? Could get worse before it gets better. At least there is a light at the end of the tunnel.

Jim - Re: "If the 820 launch had not been screwed up by Intel (not Rambus) the sales of the 820 would IMO been much higher. The 820 is a good platform but it could have been much better."

Ever wonder why the 820 launch was screwed up?

Could it have been due to RAMBUS not working correctly according to RAMBUS's own specifications?

Oh well - maybe you can list all the non-Intel Chip Sets that have successfully been launched with Rambus support.

By the way - why didn't Rambus design their own chip set - are designers more expensive than lawyers?
