15 chips in the Xeon 5600 series include the chip energy and the version 4, 6 cores. The CPU runs faster than the Xeon 5500 series chip feedback was launched in 2009.
The new chip speeds from 1.86 GHz to 3.46 GHz . All have a 12MB cache, is priced from 387 dollars to 1663 USD .

Chips using the new architecture Westmere, produced by the 32nm process should have higher performance, consume less power than the Xeon 5500 chip architecture Nehalem is manufactured using 45nm process.

The new chips have some new features to help improve speed and security systems such as AES-NI new script (Advanced Encryption Standard - New Instructions) to encrypt / decrypt data security technology hardware Intel TXT (Trusted Execution Transaction). Each six-core CPUs can run 12 simultaneous streams to process faster.
