Silvermont is a microarchitecture for low-power Atom, Celeron and Pentium branded processors used in systems on a chip (SoCs) made by Intel. Silvermont forms the basis for a total of four SoC families:
- 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. Intel had repeatedly said the first Bay Trail devices would be available during the Holiday 2013 timeframe, while leaked slides showed that the release window for Bay Trail-T as August 28 - September 13, 2013. Both Avoton and Rangeley were announced as being available in the second half of 2013. The first Merrifield devices were announced in 1H14.
Airmont is the 14 nm die shrink of Silvermont, launched in early 2015 and first seen in the Atom x7-Z8700 as used in the Microsoft Surface 3. Airmont microarchitecture includes the following SoC families:
- Braswell - consumer SoCs aimed at PCs
- Cherry Trail - consumer SoCs aimed at tablets.
Silvermont based cores have also been used, modified, in the Knight's Landing iteration of Intel's Xeon Phi HPC chips.

Erratum
Intel revealed in its Q4 2016 quarterly report that there were quality issues in the C2000 product family, which had an effect on the financial performance of the company's Data Center Group that quarter. An erratum published by Intel state there is a defect in the chip's clock, and affected systems "may experience inability to boot or may cease operation". A workaround is available. The SoC failures are thought to have led to failures in Cisco and Synology products, though discussion of the C2000 as the root cause of failure has been reported to be under a non-disclosure agreement for many vendors.
Intel released a new stepping of the C2000 series in April 2017 which corrected the bug.
