Scumbria - Re: "AMD is starting to breath down Intel's neck, and is making Intel's management a little bit nervous" No, not exactly. Here's a good summary from Anand Shimpi concerning the K6-2 350 MHz. It's pretty clear from his work that AMD HAS TO REDESIGN THE K6-2 CORE or the process - since Anand had to JACK UP THE VOLTAGE to 2.4 volts to get a K6-2 to toggle at 400 MHz. With Standard cooling, an overclocked K6-2 at 450 MHz wouldn't even boot! Cryogenic cooling was required to get the part to even BOOT at 450 MHz. {=========================================} anandtech.com "The 350MHz chip AnandTech received for evaluation unfortunately only made it up to 400MHz using normal cooling techniques on the FIC PA-2013 MVP3 test bed. In order to achieve reliable performance at 400MHz, the K6-2's core voltage had to be increased to 2.4v from the standard 2.2v setting. According to AMD, the K6-2 can handle core voltages up to 2.5v without truly harming the chip, however that does not take into account any type of harm you are causing to the CPU by overclocking it. Clocking the chip at 450MHz resulted in a frozen system at the power on self-test (POST) and failed to boot successfully. Using an experimental cooling technology similar to those used by Kryotech to thermally accelerate the K6-2, AnandTech managed to get the processor to boot at 450MHz and run through a set of gaming performance tests. The Winstone 98 (business applications) tests took too long to complete and would not run through reliably enough to obtain a score. Overall, you can expect a fairly decent percentage of 350's to be able to make it up to 400MHz, with the cream of the crop being able to hit the 450MHz marker. Is 500MHz a possibility? It doesn't seem so. Even after cooling the processor down to well below freezing, the system wouldn't even boot past 450MHz." {========================================} Paul
