"Nice try. No, the Physics are the same for both INTC and AMD. If AMD is willing to run at higher junction temperatures, then they will exhibit more reliability failures and shorter operating life. This is because device physics failures are accelerated by temperature. Thus, INTC has a different (more stringent) reliability specification than AMD" I Don't think so! Most commercial semiconductors are rated for 125 degrees C Tj max. with excellent long time reliability. Everyone is ignoring is the effect of temperature on logic switching speed. The hotter the chip the slower the switching speed. These processors are being designed with very thin logic timing margins. When the chip gets to hot, setup and hold times for the logic a violated and the processor fails until the temperature is reduced. The lower Tj max for the Intel processor is indicative of less logic timing margin then AMD processors. Regards
