Carl, you won't believe this, but I thought I saw an article showing that the CC820's performance wasn't as bad as I thought it would be. If it's comparable to 440BX, that's good enough for me. But I need the third-party web sites and/or PC Magazine to confirm that for me.

Hi all; As an aside, I was going to do a pin study on the MRH-S and MRH-R when Intel released the data sheets, but the MRH-R is still unreleased.

I'm beginning to suspect that Tenchusatsu is correct, and that the 820 roll out is almost entirely SDRAM. I am also beginning to suspect that he is correct when he suggests that the RDRAM is being tested against the i820 in order to assure functionality, and that is why they are being sent out as a bundled unit.

The Intel page discussing the i820 as a driver for SDRAM:
developer.intel.com

The Intel data sheet for the 82804 MRH-S:
Intel 82804AA Memory Repeater Hub for SDRAM (MRH-S) November 1999
developer.intel.com

The above is needed to connect the i840 up to SDRAM. There is a similar part that allows the i820 to connect up to SDRAM. Up to two of the above parts may be put on a single i840 Rambus channel, thus a total of four could be used, unless I am mistaken. This would allow a pretty good sized server memory.

Re <<Intel pushing CC820s...>>
After running the math through my head this morning, it's amazing now many chipsets and microprocessors Intel has to produce a week to keep channel happy. Intel produced 28 M microprocessors last quarter or roughly 2 M a week. Intel manufacturers 60% of the chipsets to go with those microprocessors or 1.2 M per week. Intel has to be able to deliver mass quantities of products that the market requests. The 820 fiasco really forced Intel to retreat and regroup.
Given these numbers and an almost entire product lineup overhaul but to pressure by AMD to get faster, Intel will be selling at least 90% of a NEW lineup of microprocessors and chipsets in January than they did in Sep.
In third quarter, Intel had BX chipset as the bulk of the chipset marketplace with a rapid rise of the 810 chipset on the entry level. By January, Intel will have 810 and 810e on value systems, 820 and 840 on business and workstations respecitvely and at least 50% of microprocessors will be 0.18 micron production.
The question in January will be does RDRAM really give the performance benifits for the added cost. By January, the issue of supplying the chipsets and faster microprocessors to showcase RDRAM will not be an issue. Customer acceptance will be.
