It's difficult to predict Apple's future products, but variants of the A4 chip could reach media servers, entertainment gateways or network servers for cloud storage, analysts said. The low-power chip is designed for devices that do not require much horsepower, and can be tweaked to improve processing power, graphics or communication capabilities.

A remote, but unlikely, possibility is that the A4 also be included in future Macintosh computers as a co-processor alongside Intel's processors for specific network, security or instant-on applications, analysts said. However, the hybrid computers may be more expensive, and software issues may dog systems.

The A4 chip was first unveiled in January when Apple announced the iPad. The chip now powers Apple's iPhone 4 and the Apple TV device, which was introduced this week. The system-on-chip includes an Arm processor that runs at 1GHz and a graphics core capable of rendering 720p high-definition video.

If Apple decides to expand A4 to more devices, likely candidates would be low-power servers, said Jack Gold, principal analyst of J. Gold Associates.

"I suppose A4 could make its way into light 'server' devices, such as media servers where you don't really need all of the power of an [Intel Core] i3 or i5 chip. And there are companies already looking at Arm-based servers, so I would think this might be a direction for Apple to pursue," Gold said.
