Maxwell, Re: "If you draw the speed of the transistor versus the temperature you will find that the speed of the transistor switching to the on state increase significantly as the temperature is dropped. At -50C the speed improvement is about 40-50%." But Maxwell, this goes "against" everything that Ali says ... Remember, it's the "architecture" not the process, according to Ali Babble. <ggg> Re: "Yousef pretended that he knows Intel 0.25um PII process but he really doesn't know it." No, Yousef does know the .25um process ... Are you still trying to say that +- 20nm is not good enough control at the gate level ?? Well Maxwell considering that "state of the art" SEM's have repeatability accuracy of about +- 5nm, you have a hard enough time with a +- 20nm spec . You need to learn more about "gauge tool studies" and process control. Make It So, Yousef

Maxwell - Re: "Kryotech is the only company that makes such device to cool down the CPU. It was used to demo a 0.35um PII running at 400MHz." WRONG ! AGAIN ! Intel used a recirculating, refrigerated ice-water bath - to cool the 0.35 micron KLAMATH - not a KRYOTECH cryogenic device. And the Klamath ran at 433 Mhz during that demo. You play fast and loose with the facts - maybe that explains why the yield problems in MegaFlop 25 lasted so long. Paul {========================} Intel makes it a race with 451MHz Klamath processor By Andy Santoni InfoWorld Electric Posted at 5:59 PM PT, Feb 7, 1997 SAN FRANCISCO -- While the microprocessor horsepower race still goes to Digital's Alpha architecture at 600 MHz, Intel on Friday surprised attendees at the International Solid State Circuits Conference here by disclosing that it has pushed the P6 Pentium Pro architecture to as fast as 451 MHz. Scheduled to present a paper on a 300-MHz Klamath processor, Mustafiz R. Choudhury, design manager at Intel's Microprocessor Products group, in Santa Clara, Calif., instead disclosed that the processor is running at 433 MHz. And, he said, Intel researchers have seen 451-MHz operation in the laboratory. Choudhury called the device "the highest performance Intel Architecture-compatible microprocessor." The 7.5 million-transistor processor offers a projected performance of about 12 SPECint95 in its 300-MHz version, he said. However, Choudhury stressed that the processor is a technology disclosure and not an available product. The device's power dissipation bears this out. While he would not say how much power the chip dissipates, Choudhury admitted that it requires an ice-water heat sink to maintain an operational temperature. A system based on the device and running at 400 MHz was demonstrated for the press after Choudhury's presentation, and this computer required a cooling system hidden under the table.

Maxie, Kryotech may be one of the few who sell such coolers on the open market but assorted cryo coolers using freons, Peltier devices, heat pipes to cold sinks and more have been around ever since the 70's. Take a look at the insides of the supercomputers. Many have full Freon systems, others coooled water, others have peltier coolers to a water sold sink and so on, many assorted mechanisms . Bill

Re: "There is no need for me to prove anything here. " There sure is, if you want credibility. Re: "Yes I am that good. Let me give you a hint. If you draw the speed of the transistor versus the temperature you will find that the speed of the transistor switching to the on state increase significantly as the temperature is dropped. At -50C the speed improvement is about 40-50%. At room temperature (water cooled) the improvement is minimal. Kryotech is the only company that makes such device to cool down the CPU. It was used to demo a 0.35um PII running at 400MHz." You're that good??? Even a non expert like me knows that voltage changes the curve, just like temp does. AMD has used this to goose up their slower processors. And Intel did NOT use a Kryotech device, they used a water cooled system. That won't get you to -50C. If you didn't know this, why should we believe your other claims about Intel's process, or AMD's for that matter? This is another example of you shooting off your mouth and proving you are NOT the expert you pretend to be. Go back to making up hype Maxwell, it's the only thing you do well. EP
