Energy efficiency is important to AMD, allowing you to enjoy a cool, quiet PC while saving energy and reducing heat, noise and the effect of your computer on the environment. Energy efficiency innovations include Cool’n’Quiet, AMD CoolCore and AMD Smart fetch. These technologies reduce power consumption and processor activity. You’ll experience up to 50% energy efficiency over previous AMD Athlon II processors.
AMD Athlon II processors also offer support for Virtualization Technology. You can run virtual environments on one system with ease, allowing you to use legacy programs on a separate operating system. Also providing 64-bit support, this processor can handle the most demanding programs with ease. Add the convenience and power of multi-core processing and enjoy the benefits of energy efficiency with an AMD Athlon X2 4450B today!
