Intel has announced four new quad-core Xeon models that use a halogen-free packaging technology.
The Quad-Core Xeon L5430, X5470, X5492, and X5270 processors run at clock speeds ranging from 2.66GHz to 3.5GHz. The 5400-series chips are available immediately and the X5270 will be released in the coming months.
Intel is working to use halogen-free packaging for all of its chips. The first halogen-free chips from Intel were the Atom line, released earlier this year.
The use of halogen-free packaging marks the latest step in Intel's efforts to curb the environmental impact of its chips. Last year, it began using lead-free solder with its Penryn family of chips.
