Intel continued their 45nm push with the announcement of their first four halogen-free Intel Xeon processors today. These processors utilize their new Hafnium-based high-k metal gate formula which in turn helps to reduce the environmental impact these processors make. The new Xeon processors include three quad core 5400 series processors - the X5492, X5470, and L5430, as well as a new dual core Xeon X5270 processor. The specs and prices are as follows:

• Quad core Intel Xeon processor L5430 - 2.66GHz 1333MHz 50 Watts - $562
• Quad-core Intel Xeon processor X5470 - 3.33GHz 1333MHz 120 watts - $1386
• Quad-core Intel Xeon processor X5492 - 3.4GHz 1600MHz 150 watts - $1493
• Dual-core Intel Xeon processor X5270 - 3.5GHz 1333MHz 80 watts - $1172

Intel also announced that all previously launched versions of the Xeon 5200 and 5400 series will now be halogen-free. To make life easier for hardware manufacturers, these new processors are drop-in compatible with existing Intel dual processor platforms that been in the market since 2006.
