Summarize this article for a 10 year old
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:[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.

Predecessor(s) | Bonnell Saltwell |
Successor(s) | Airmont (die shrink), Goldmont (new microarchitecture) |
Silvermont is the successor of the Bonnell, using a newer 22 nm process (previously introduced with Ivy Bridge) and a new microarchitecture, replacing Hyper Threading with out-of-order execution.[2]
Silvermont was announced to news media on May 6, 2013, at Intel's headquarters at Santa Clara, California.[3] 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.[4] Both Avoton and Rangeley were announced as being available in the second half of 2013. The first Merrifield devices were announced in 1H14.[5]
According to the Tick–tock model 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.[6] Airmont microarchitecture includes the following SoC families:[7]
- 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.
