Companies are trying to harness computing power available in data centers in the most energy efficient way. There is a growing interest in low-power processors like ARM and Atom S, especially from Web-serving companies like Facebook and Google.

The new Atom S chip will have 64-bit and virtualization features, which is key for cloud deployments. ARM's 32-bit processors go into most smartphones and tablets, and the processor design company earlier this week said prototype servers based on its first 64-bit architecture will be released as early as late this year, or by the middle of next year.

The second chip in the Atom S lineup will be Avoton, which will be released next year and be made using the 22-nm process. The chip will have integrated fabric to virtualize storage and networking. Bryant did not provide a specific ship date for Avoton chips.
