"We thought at the time we could approach 200 watts," Rattner said. However, the PC industry balked at the cooling requirements that would have been needed to prevent 200-watt processors from melting systems, he said. And the 90-nanometer technology was more prone to electrical-current leakage than previous manufacturing technologies, making 90-nanometer chips hot even when they weren't running at full power.
Growing concerns over global electricity useage has with no doubt impacted this research somewhat, as we see almost all industries now placing huge focuses on power reduction. Intel says their new low-power design for CPUs is finished, and they will be utilizing it in the near future. Now their focus is on the motherboard.
