With prices on RDRAM lowering, the incredible increase in memory bandwidth and Rambus in dier need of a new partner why not AMD and RAMBUS. AMD, nVidia and RAMBUS could put their heads together come out with a shared memory architect that is a quad channel dual RIMM set up that totally kicks the sh*t out of Intel's so far un-inspiring plans. nVidia has already got half of it down with the introduction of nForce. Just an idea...
AMD would have to be completely mad not to have some backup chipset it could use with RDRAM. The big issue for them would be to make the latency much lower than RDRAM provides so we may well see quad RDRAM channels and a large L3 cache They may well get NVidia to do it in which case the chipset prefetch could be incorporated.
Of course they may well incorporate CPU mods as well such as a better branch predictor which would help whatever memory type was used.
AMD doesn't need a quad channel rambus solution, yet. That's like 6.4 GB/sec bandwith, and Athlon systems don't need nearly that much. The nForce chipset provides just about all the Athlon needs right now. Until Athlons start working off a 333 or 400 mHz bus, whats out there is fine, but even when that happens we'll see DDR SDRAM at PC2700 and PC3200, in dual-channel like configurations that will be offering up to 6.2 GB/sec bandwith.
Also, RDRAM is not where the future's at. Memory manufacturers expect DDR SDRAM to account for some 70% of memory sales and production a few years from now, while RDRAM will abount for about 12%. There's no reason for AMD to go a RDRAM solution right now, being that it is a technology that is still unproven on how great it is.
The funny thing about RDRAM is how it’s supposedly sooooo much better.
But in real world performance AMD systems perform just as good or better then P4’s with there supposedly superior RDRAM.
I think the high latency in RDRAM nullifies it’s bandwidth advantage. When the P4 comes out with DDR then we will see the truth about RDRAM. I can’t wait. What about U?
Thx & Cya
BTW
RAMBUS = a company that everybody hates.
RDRAM = Another type of memory featuring high bandwidth with high latency.
I see the two used interchangeable which is wrong.

AMD doesn't like RAMBUS and RDRAM. They want DDR-SDRAM to become the next memory standard. I have no doubt they're preparing a chipset that supports RDRAM, as a contingency, but they won't release it unless they absolutely have to.
