Intel Corp. has launched its first four energy-efficient halogen-free 45nm Intel Xeon processors.

Lead and halogen materials have been used by the entire electronics industry for decades and there are concerns about the impact they’re having on the environment. Removing the materials makes the processors “eco-friendly.”

Much of the energy efficiency these new processors provide comes from Intel’s 45nm manufacturing capability and its new transistors that use a Hafnium-based high-k metal gate formula. In addition, all previously launched versions of the Intel Xeon 5200 and 5400 series will now be halogen-free.

The processors are drop-in compatible with existing Intel dual processor platforms that have been in the market since 2006. The Quad-Core Intel Xeon Processor 5400 Series consists of the new X5492, X5470 and L5430 processors, the fastest of which clocks in at 3.4GHz. The low voltage version uses 50 watts of power (12.5 watts per core). The Dual-Core Intel Xeon Processor X5270 runs as low as 80 watts with frequencies up to 3.5 GHz.

Systems vendors supporting these new processors including Asus, Dell, Fujitsu, Fujitsu-Siemens, Gigabyte, HP, IBM, Microstar, NEC, Quanta, Rackable Systems Inc., Sun Microsystems, Supermicro, Tyan and Verari Systems. The new 5400 series processors are available now, and the X5270 will be available this fall.
