Pomp, I expect 2GHz by early 2002. The requirements for DRAM bandwidth will exceed what SDRAM can provide, and a different solution will be required. The question then becomes, DRDRAM, DDR, or something else? I am not very familiar with the electrical noise issues discussed on the thread, and rely on the information presented by others. I hope that this forum will provide me with some information towards this end. At some point in the not too distant future, I will have to make this decision for a design, and would like to make the correct choice. Regards, Scumbria

Re: Let's say, for arguments sake, that Intel expects to market a 2.3 [Gigahertz] CPU ... DDR 266 supports a 2.1 GB data rate compared to Rambus 800 supporting a 1.6 GB data rate. Since Carl has now pointed out the astounding fact that it will be as easy or easier to fit 2 DDR channels on a motherboard instead of 2 Rambus channels, the question becomes: at what speed does Rambus begin to show its insufficient data rate weakness. Regards, Dan

Hi pompsander; Re the memory bandwidth situation of 2003. When 2003 arrives, solutions for the engineering problems of that time will also arrive. The whole theme of the DDR movement is no technology before its time. Let the engineers of 2002 handle the bandwidth problems of 2003. One of the problems with trying to predict too far into the future with technology (and tech stocks) is that the ground rules change so quickly. With Rambus, the ground rule that changed was the cost of pins. Back when Rambus started, chips were connected to pins by something called "bonding wires", which were tiny wires individually welded at one end to the silicon chip, and at the other end to the package. These were visible inside the olde EPROMs, for instance. Back then, every pin was expensive. Nowadays, BGA and flip-chip technologies have eliminated bonding wires, and pins are darn near free. The pin expense is now more in the cost of the board they connect into, rather than the cost of the package. (Too many pins causes an increase in the number of board layers.) That is why the new 288Mb RDRAM chips are being put into packages with 92 pins instead of the 76-pin packages that the previous generation RDRAM went into. Simply put, package pins are (almost) free. Who knows what technology will show up in the next 4 years. The next big hurdle in reducing the cost of connecting chips together into systems (which is essentially Rambus' mandate), is the cost of the board, not the package. My bet for the solution to the board cost problem is MCM, which is why every now and then I post a set of links to MCM articles. -- Carl

pompsander, OT The reason the voice recognition is so rare is not because of lack of processing power, but because it is impractical, and probably slower than typing or clicking a mouse. Some people who are computer illiterate (a shrinking minority) are looking to voice recognition to save them from their stupidity. But if one is too stupid to operate a computer, how will this person know what to tell the computer? How will the computer understand? When someone who is not very literate with the computer asks me something about using a program, I sometimes have a hard time understanding from their words what it is they want to do, and what I have at my disposal is experience, huge library of heuristic algorithms in my brain, some clue about the user / his abilities, and rough idea what he is working on.
