Check out these prices Notice the sudden price drop of the 366 and 350MHz. Lowest AMD Chip Prices at www.Pricewatch.com Sunday, May 31, 1999 Price Date K6-III 450 - $212 5/31 K6-III 400 - $165 5/28 K6-2 475 - $153 5/28 K6-2 450 - $99 5/31 K6-2 400 - $68 5/31 K6-2 380 - $66 5/27 K6-2 366 - $67 5/26 K6-2 350 - $47 5/29 Sunday, June 6, 1999 Price Date K6-III 450 - $210 6/05 K6-III 400 - $160 6/05 K6-2 475 - $150 6/04 K6-2 450 - $97 6/05 K6-2 400 - $67 6/05 K6-2 380 - $59 6/05 K6-2 366 - $66 6/03 K6-2 350 - $47 6/04 Sunday, June 13, 1999 Price Date K6-III 450 - $208 6/13 K6-III 400 - $154 6/12 K6-2 475 - $147 6/11 K6-2 450 - $102 6/12 K6-2 400 - $72 6/12 K6-2 380 - $55 6/12 K6-2 366 - $73 6/10 K6-2 350 - $48 6/12 Sunday, June 20, 1999 Price Date K6-III 450 - $212 6/20 K6-III 400 - $154 6/16 K6-2 475 - $143 6/20 K6-2 450 - $101 6/19 K6-2 400 - $68 6/20 K6-2 380 - $55 6/19 K6-2 366 - $66 6/20 K6-2 350 - $38 6/19 One thing these numbers doesn't show - During the first 3 weeks, the 350's price was the same; now the price is lower, but it isn't just one vendor. Practically all the vendors have dropped their prices the past few days, which I believe signals they are getting new chips at lower prices. And if they are selling the chips for $38, I doubt AMD is making much money on them. I don't remember the prices of the 300 and 333 last Q at this time, but they were probably equal or less than what the 350's are right now. Also, Compaq and HP came out with new PCs with the 350 in it about 2 weeks ago. The 366's price dropped because of only 1 vendor today. So if the price continues to drop this week, we will know AMD is trying to get rid of these chips too. The 380's price has been relatively stable. The 400's price has started to drop this week. All these processors I have mentioned are below the $78 ASP AMD had last Q. I supply what I see, y'all supply what you know. Oh, yeah. I forgot to say this kind of hints at an inventory build up for those MHz. But this doesn't hint whether or not it is *2M.*

<What makes you think that the "north" bridge can't send these messages simultaneously? Remember, every processor has a separate "bus", is not it?> Doesn't matter. The chipset has to receive the request from the processor before it informs the other processors. It takes time to relay that request. On a shared multiprocessor bus, all processors simply watch the bus. No additional latency. On the other hand, this problem can be solved using snoop filters on the north bridge. This way, the chipset knows exactly which lines are owned by which processors, so snoop traffic can be reduced tremendously. Of course, a snoop filter adds additional cost to the chipset (128K per K7 w/ 2MB L2 cache, for a total of 1MB of snoop filter for an 8-way K7 system), but it's not all that much compared to the entire cost of a 4 or 8-way K7 server. <Second, how did you manage to do a research on a non-disclosed-yet system architecture?> Because the P2P architecture has been done before. Alpha isn't the inventor of P2P, you know. Tenchusatsu
