AppleInsider reported Friday that Apple has decided to use Intel's upcoming low-power Silverthorne chip in "not one but multiple products currently situated on its 2008 calendar year product roadmap." Silverthorne is Intel's latest push to capture the handheld/mobile phone market as part of a product concept called the Mobile Internet Device.
The report goes on to say that the most likely candidates for Silverthorne are a 3G iPhone and the Newton-like tablet computer that AppleInsider reported on earlier in the year. Based on what we know about Silverthorne, I think the subtablet rumor might make sense, but a Silverthorne iPhone is unlikely.
Intel plans to release more details about Silverthorne at the Intenational Solid State Circuits Conference in February, but we already know from the advance program, and from what Intel said about the chip last year, that we can expect Silverthorne to behave like a much smaller 2004-era Pentium M processor that consumes just a watt or two of power, compared with the 35 watts consumed by Intel's Core 2 Duo notebook processors of today.
