Concept
Silvermont
Summary
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 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.
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.
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. 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.
Silvermont was the first Atom processor to feature an out-of-order architecture.
