<CuMine is testing fine at 600 MHz at room temperature, but degrades with higher temperatures. Could this mean a process problem?> Could be anything, too little information. Actually, if a 0.25u design can routinely run at 600MHz at room temperature, those 600MHz for 0.18 is not an achievement at all. It is called "sux". Speaking theoretically, the shrink to next feature size is supposed to double the speed of design, so we should expect CuMine at about 666Mhz at start (since 0.25 P-II were introduced at 333). BTW, in Intel roadmaps the CuM was listed at 533+, so officially they are on tracks. I guess the interconnect takes it's toll. It was predicted at a time when Intel's officials proclaimed that copper in not necessary for 0.18. Time to pay for missing "inflection point". - Ali
