Intel's New Chips Leaner and Greener

Loraine Lawson

By the end of this year, Intel's processors will be leaner, meaner and greener. The chip maker is now using its 45-nanometer transistor technology to build chips.


Just how small is 45-nanometers? It's so small, you could place 10 nanometers on top of one red blood cell, says an Intel sales manager quoted in this Inquirer article. Previous to this new manufacturing process, Intel manufactured 65-nanometer chips.


For the past few years, Intel couldn't build smaller chips because of power leakage. The company says it's solved that problem with a Hafnium-based High-K (Hi-k) metal gate transistor technology, reports the Inquirer. So, the new processors are not only smaller, but they're more energy efficient.


According to Green Computing, the 16 new chips also are lead free.The new chips will be used in Intel's Xeon processors and Intel Core 2 Extreme quad-core processors, which are placed in servers and high-end PCs.


By this time next year, Intel says it will be able to produce 32-nanometer, halogen-free chips, according to IT Jungle.


So far, only two U.S.-based fabrication plants are making the 45-nanometer chips, but two more plants should be producing the chips by 2008.
