  1. Re:ohm on Top Ten Intel Slipups · · Score: 1


    there was a day when you were all sitting around eating chips and talking about how kick-ass

    I second that: when I was in highschool in 1986 the BBS scene was full of discussion on the 386 and upcoming 486 (and CGA porn). However, don't forget that anyone who has ever used the word 'l33t' probably wasn't born then... but I do find it interesting how the discussions went from really understanding the architecture (when masm was king), to just politics as usual. Since commodity programming has become so decoupled from the architecture, intellectual discourse on CPU architecture isn't in demand among the throngs. It's mostly a bipartisan thing these days. If everyone would stop shopping at Old Navy, we'd all be able to get along a little better. What the hell am I talking about.

    "...Light" sounds interesting, but not because of the critique ("..lyrical and sureal..."? oh please). I mean, kudos to the scifi authors for writing scifi, but writing a book with QM vs GR as a key plot point just seems kinda weak. I dug Cryptonomicon's portrayal of Turing and his buds, but that wasn't a main plot in the book, it was just food for thought.

    C'mon, either pen some really esoteric SciFi, or let's hear a story about how Newton shafted Leibnitz on the differential calculus.

    I'm a HUGE fan of Dr David Goodstein's "The Mechanical Universe" series, and the little skist they filmed about the individuals are fascinating. Like Galileo being persecuted (or Bruno, for that matter). Hell, Kepler's madness would make a great story too.

"Excalibur" is, IMO, the best D&D movie to date, even though there weren't any cool monsters. "Time Bandits" and the "The Adventures of Baron Munchausen" are also loads of fun and resemble D&D-like fantasy.

    And if the Rambus Scam had gone as intended, Intel's

    It wasn't a scam. The executives that made the dumb decision based on internal suggestions from analysis engineers realized there was no chipset vehicle to deliver higher performance processors based on SDRAM. The executive decision was rooted in fear that their latest CPU wouldn't look as fast b/c of memory bottlenecks.

    Remember, executives were thinking of 2001 in 1996. The were thinking of the future in terms of: bazillions of polygons per sec for 3D T&L, endless streams of motion comp vectors for DVD/MPEG4 playback, and rapid searching of large phoneme databases to compute hidden markov models* in text-2-speech and speech-2-text --- that's a LOT of memory bandwidth, kids. They weren't thinking SpecFP. They weren't thinking Winbench.

    Now you all considered it a scam b/c Intel made a partnership to supply high volume for Rambus, while Rambus would let them see their IP. Why is that a scam? People could by a VIA chipset with SDRAM and slap a PIII into it, can't they? It runs better than 820, doesn't it? How is that bad for consumers? Intel stumbled trying to make a high performance chipset. They weren't out to bone the masses. How would their partnership with Rambus stifle competition??? It hasn't and it wouldn't have if RDRAM panned out on all fronts.

    So does this mean that any decision made by an executive is political? I'm challenging the perception in this thread that Intel is out to screw the masses. What is the problem with my position?

    Claims are cheap, evidence is scarce. The statements made here are all that count, and those statements demonstrate a profound ignorance of the technologies and issues involved. If you know more, use that knowledge in your posts.

    Exactly. That's why I don't understand why you can call me 'ignorant'. What wasn't clear about my statements? I made observations about Intel's decision based on products and timeline. The person challenging me piped up and said I didn't know anything and then proceeded to talk about latency, and then slammed me personally again.

    In my view I made the more intelligent posts. Should I have seeded my post with buzzwords? Ok: skew, timing, reflection, leadoff, page miss, row miss, page hit, column adress strobe. There, now you know I'm smart.

    I supposed I could spout even more buzzwords about memory heirarchies -- which the previous poster said I know nothing about, and was fairly irrelevant to the discussion. Sure, most benchmarks run in the cache, blah blah blah, Spec, blah, Ziff-Davis, blah. (Maybe some genius will now explain to me what I cache is.)

    Again, because you completely ignored my original point: Intel was extrapolating into the future in 1996. That's why they wrote the first version of ZD 3DWB'97 and did the 740 dance. Everything pointed toward 3D as the future and only RDRAM would support AGP 2/4X (NGP) and superfast FSB.

    Someone made a claim that Intel was trying to corner the market by using RDRAM. Since it is obvious there is _no_ market for Intel to corner wrt memory, and based on the changes in intel's technology, I simply pointed out the obvious reason why intel tried to transition.

    But apparently I forgot to slam intel in the process. So much for trying to raise awareness.

    Intel went with RDRAM for 3 reasons, BANDWIDTH, BANDWIDTH, and BANDWIDTH. Intel was the only company trying to do something about the frontside bus bottleneck. They wanted faster frontside busses AND faster AGP being served by one memory channel. SDRAM honestly doesn't have the bandwidth, that is why there are 16, 32 and 64MB of graphics memory on all of your shiney Voodoo or GeForce cards: b/c SDRAM can't handle it.

    Intel wanted faster FSBs and graphics performance, so they absolutely had no choice but to go with RDRAM.

Once we reach that level, then the creme de la creme will be within reach of the real brainbenders.
