Silvermont is a microarchitecture for low-power processors used in systems on a chip (SoCs) made by Intel. Silvermont will form the basis for a total of four SoC families:[1]

  • Merrifield and Moorefield  – consumer SoCs intended for smartphones
  • Bay Trail – consumer SoCs aimed at tablets, hybrid devices, netbooks, nettops, and embedded/automotive systems
  • Avoton – SoCs for micro-servers and storage devices
  • Rangeley – SoCs targeting network and communication infrastructure.

Silvermont was announced to news media on May 6, 2013 at Intel's headquarters at Santa Clara, California.[2][3] Intel has repeatedly said the first Bay Trail devices will be available during the Holiday 2013 timeframe, while leaked slides show the most recent release window for Bay Trail-T as August 28-September 13, 2013.[4] Both Avoton and Rangeley were announced as being available in the second half of 2013. The first Merrifield devices are expected in 1H14.[5]

Design

Silvermont is the first Atom processor to feature an out-of-order architecture.[6]
