Intel's Silvermont Architecture Revealed: Getting Serious About Mobile
The most frustrating part about covering Intel's journey into mobile over the past five years is just how long it's taken to get here. The CPU cores used in Medfield, Clover Trail and Clover Trail+ are very similar to what Intel had with the first Atom in 2008.
Context & Ripple Effects
Intel's mobile Atom line has been running on essentially the same core for five years: the next-generation Atom details Intel laid out in late 2009 never translated into a new microarchitecture, and the 32nm Medfield SoC that leaked in December 2011 still shipped cores recognizably descended from the original 2008 Atom. Silvermont is the first ground-up redesign of that line, which is why the announcement traveled unusually far — Reuters, Bloomberg, ZDNet and VentureBeat all carried it on the day.
The timing fits a broader pivot visible across Intel's spring 2013 moves: CEO Paul Otellini personally lobbied the FCC backing SoftBank's bid for Sprint at the end of April, Haswell is set to debut at Computex with a June 3 launch, and February's scaled-back Itanium roadmap already signaled resources shifting away from legacy server silicon toward growth markets.
First-order effects
- Phone and tablet OEMs evaluating Intel designs finally get an x86 part built this decade rather than a refreshed 2008 core, giving Intel's device win rate its first real architectural argument since Medfield.
- Intel's own messaging hardens from 'we're present in mobile' to 'we're competing' — the same week Otellini's Sprint endorsement showed the company staking strategic capital on wireless.
Second-order effects
- ARM licensees selling into tablets and low-cost notebooks — the segment where Clover Trail was already appearing — face a credible performance-per-watt rival for the first time, pressuring their own roadmaps ahead of Haswell's June arrival.
- Foundry and manufacturing partners gain leverage from Intel's claim that its process lead now extends to mobile-class parts, tightening supply negotiations for anyone sourcing both x86 and ARM silicon.
Third-order effects
- If Silvermont's cadence holds, the x86-versus-ARM boundary in consumer devices erodes from both sides, forcing platform decisions to be made on ecosystem and integration rather than instruction set.
- Combined with the Itanium retreat and the reported search for external CEO candidates, the architecture refresh points to Intel reallocating engineering and leadership capacity away from legacy franchises toward mobile and low-power silicon.
The trend: Mobile silicon is entering a phase where Intel's process and architecture cadence, not ARM's incumbency alone, sets the competitive pace for phone and tablet chips.
