When it comes to mobile processors, integration is the key to success.
Even though Intel
Intel's Medfield Atom chip hopes to make a big dent in the ARM-dominated mobile market this year, so this battle is just getting warmed up. At the International Solid-State Circuits Conference, or ISSCC, Intel just detailed a research project it's working on: a dual-core Atom SoC with integrated Wi-Fi, codenamed Rosepoint.
The chip is built on a 32-nanometer manufacturing process, and while still years away from actually seeing the light of day, it represents a major advancement in chip integration. Wi-Fi integration is a particular challenge because wireless radios and processors both give off radiation that can interfere with each other. This level of integration promises to bring even more efficiencies in power consumption and potentially boost signal quality.
Intel is looking at using digital RF chips instead of traditional analog ones to accomplish this, as they are simpler and easier to shrink down to sizes necessary for integration. Intel Chief Technology Officer Justin Rattner said, "With a digital approach to radio, you can bring the benefits of Moore's Law to RF and radio circuits." The company also uses noise-canceling and radiation-shielding methods on the chips to cope with possible interference.
While this announcement is still just a research project in the works, it has some serious implications in the mobile-processor space in the longer term and is an example of why Intel is a credible threat to ARM. Intel has some deep pockets and knows where it needs to focus its R&D, while it enjoys efficiencies from vertical integration as the only remaining domestic chipmaker that doesn't outsource manufacturing.
Intel is a one-of-a-kind leader, so I'm also going to give the chip Goliath an outperform CAPScall today. As an ARM shareholder, I still hope ARM can defend its mobile turf against the Intel invasion, but either way, Intel should be a winner.
