Atom is asystem on a chip (SoC) platform designed forsmartphones andtablet computers, launched byIntel in 2012.^[1] It is a continuation of the partnership announced by Intel andGoogle on September 13, 2011 to provide support for theAndroid operating system on Intelx86 processors.^[2] This range competes with existing SoCs developed for the smartphone and tablet market from companies such asTexas Instruments,Nvidia,Qualcomm andSamsung.^[3] Unlike these companies, which useARM-based CPUs designed from the beginning to consume very low power, Intel has adapted the x86-basedIntel Atom line of CPU developed for low power usage in netbooks, to even lower power usage.

Since April 2012, several manufacturers have released Intel Atom-based tablets and phones as well as using the SoCs as a basis for other small form factor devices (e.g. mini PCs andstick PCs).

In April 2016, Intel announced a major restructuring, including the cancellation of theSoFIA platform. It was reported by many news outlets that Broxton (the final version in the Atom line) was cancelled.^[4][5][6][7]

In Q1 2014, Intel launched its fully Android compatible smartphone platformMerrifield based on a 22 nm SoC. It was followed by its platform refresh Moorefield in Q4 2014.^[76]

While Penwell SoC supports, in addition toMicrosoft Windows, bothLinux andAndroid operating systems, Intel has announced that it will not provide support for Linux on Cloverview family of Atom systems-on-a-chip.^[97][98] This announcement has caused strong negative reaction from open source proponents.^[99] A few days later Intel issued a statement saying that it h27x0 series). The Clover Trail+ platform was later released targeting Google Android (z25x0 series).^[100]

The last version ofWindows 10 to support Cloverview is the Anniversary Update (version 1607) until January 10, 2023 when the last public security patch KB5022289 was released;^[101] later versions of Windows 10 and all versions ofWindows 11 cannot be installed.^{[102][103][104]}

Z2760 Cloverview has introduced two new power states: S0i1 and S0i3.^[105] The S0i1 state is intended to be used when the display is on but the user does not actively interact with the device; it consumes power in mW range, and can be entered/left in microseconds. The S0i3 state is intended to be used when the device display is off; it consumes power in microwatt range, and can be entered/left in milliseconds. As a result, Intel claims longer standby battery life (up to three weeks for a typical tablet).^[105]

Airmont-based Atom platforms will be codenamed Moorefield (smartphones)^[106] and Cherry Trail (tablets)^[107][108] using the Anniedale and Cherryview^[109] SoCs.

In May 2011, Intel announced an accelerated roadmap for Atom System-on-Chip (SoC) products, introducing the22 nmSilvermont microarchitecture in 2013.

• Tangier (Merrifield): Designed for smartphones.^[110]
• Valleyview (Bay Trail): Targeted at tablets, featuring Intel's 7th generation GPU, which provided a 4–7× improvement in performance over previous Atom GPUs.^{[111][112][113]}
• Rangeley and Avoton: Developed for networking and storage applications, part of the Edisonville platform.^[114][115]

The14 nm microarchitecture succeeded Silvermont in 2014, with the following Atom platforms:^[116]

• Moorefield: Developed for smartphones.^[106]
• Cherry Trail: Designed for tablets, using the Cherryview SoC.^[107][108]

Intel introduced the Goldmont (2016) and Goldmont Plus (2018) microarchitectures, featuring improvements in efficiency and performance. Key platforms included:

• Apollo Lake (2016): Targeted at low-power laptops, Chromebooks, and embedded systems.
• Gemini Lake (2017): An enhancement over Apollo Lake, supporting higher clock speeds and improved integrated graphics.

The planned Morganfield (smartphones) and Willow Trail (tablets) platforms, based on the Broxton SoC,^[106] were canceled in 2016 as Intel shifted its Atom focus toward embedded and IoT devices.^[117]

In 2019, Intel introduced the Tremont microarchitecture, which improved instructions-per-cycle (IPC) efficiency. Tremont-based Atom processors included:

• Elkhart Lake (2020): Targeted at industrial IoT and embedded applications.[8]
• Jasper Lake (2021): Designed for low-power consumer laptops and Chromebooks.[9]

Introduced in 2023, Alder Lake-N processors succeed the Atom series, utilizing Gracemont efficiency cores for budget-friendly laptops, Chromebooks, and entry-level desktops. Unlike previous Atom architectures, they integrate technologies from Intel’s mainstream Core series, improving performance and efficiency.

Intel continues advancing low-power SoC architectures, incorporating Intel 4, Intel 3, and Intel 20A process nodes with RibbonFET and PowerVia technologies.^[118]

Subsequent developments integrate Atom-class efficiency cores into hybrid architectures:

• Meteor Lake (2023): Intel 4, modular tile-based design, Crestmont efficiency cores, first use of EUV lithography.
• Arrow Lake (2024): Expected to refine performance-per-watt optimizations.
• Lunar Lake (2025): Projected 3× AI performance improvement over predecessors, targeting AI-driven applications.

These processors represent Intel's continued iteration of its low-power CPU architectures, with a focus on efficiency and AI capabilities.
