Intel Corp., the world’s largest microchip manufacturer has announced four new Xeon “Harpertown” processors. According to Intel, the revamped server processors under the 5000 line include three quad-core processors and a dual-core processor built using 45nm technology.

The faster and greener processors include the 150 watts 3.4GHz X5492, the 120 watts 3.5 GHz X5470, and the 50 watts 2.66Ghz X5430 quad-core processors. Also included is the 80 watts 3.5GHz X5270 dual-core processor. These processors are the first in Intel’s server family chips to use halogen-free packaging materials, making them environment-friendly since halogens release toxins if incinerated.

The quad-core models are now available while the dual-core model is expected later this year. Since these processors are used in servers, they are not that cheap, the X5492 is $1493 and the X5430 is $562.
