When you say obsession how did that manifest itself in the real world?
I mean Intel being the ones in charge of their own production schedule did they decide to stop the production of say the 810/815 chipsets to make the 840 chipsets and then go on to force those 840 chipsets onto the world?
Or did they pay off the big OEMs like HP and Dell to sell their 840 chipset systems by offering them cheaper than they should have been? to make their sale more attractive to the OEM?
Maybe starve the market of the 810/815 to force 840 sales?
Or did they just run an aggressive marketing campaign in the hope that people will take up the product they were making?
They basically starved the market of non-RDRAM chipsets.
And they did so in two phases:
1) Phase 1. i820. Basically, if you wanted 133MHz FSB, 4X AGP, UltraATA 66, or any of the other platform improvements, and you wanted an AGP slot, then you needed an i820 with RDRAM.
When the market resisted and 440BX stuck around much longer than expected, they decided to come up with their MTH to 'translate' SDRAM into RDRAM. Then that... turned out to be a snafu and got recalled. So they gave away 128 megs of RDRAM to everybody who had the Intel CC820 board.
Then they were forced to launch the i815, which got you all the nice platform improvements over the 440BX but with SDRAM support. That was the end of RDRAM on the PIII platform - maybe a few high-end Dells got sold with i820/i840 but that's about it.
(As an aside, as someone who would never have touched a VIA chipset back in the day and who is still shopping for an additional retro system, I am continually astounded at how many socket 370 boards/big OEM systems are out there with Via's Apollo 133 chipsets. That's the legacy of Intel not offering a decent non-RDRAM chipset before the i815.)
2) Phase 2. Pentium 4. The Pentium 4 launched with i850 and RDRAM only. I think the MTH was supposed to come back, but didn't. So, again, if you wanted Intel's flagship processor, you needed RDRAM.
After close to a year, they launched the first iteration of the i845, but that only supported PC133 SDRAM, not DDR, and performance was mediocre. I'm googling this and reading old AnandTech articles, apparently it was crazier than I remembered - the i845 could do DDR, but Intel strictly, strictly prohibited motherboard manufacturers from making DDR boards until at least Jan. 1, 2002. And I haven't researched it and I don't remember offhand, but I'm pretty sure the DDR i845 boards remained unappealing alternatives to i850E and it was only with i865/i875 that DDR platforms for P4 really became good.
So basically, for the first 15ish months at least, if you wanted a P4, you had to get RDRAM.
How that manifested itself in the real world? If you weren't VIA-phobic, in late 2001, you were getting a KT266 motherboard with your Athlon XP on socket 462.
Intel had a chipset problem from late 1999 until the launch of the i865 in 2003. There was a gap of about a year where the i815 provided a decent alternative, at least if you could live with the max 512 megs of RAM at a time when 256 megs of SDRAM started costing $60CAD. But otherwise, Intel's chipset options were always flawed because the decent/high-end option was only RDRAM.
(Disclaimer: I had a Willamette P4 with a gig of RDRAM. Never had a real problem with it, although what annoyed me was that the Northwoods that came out a month later used PC1066 RDRAM and mine was PC800... so oops, zero upgrade path for me.)
