Diamondville/Silverthorne-
They share lot of the features. Mostly binning differences. All feature 2-issue wide, in-order core with 512KB L2 cache and 56KB L1 cache.
Silverthorne features the best power management. Has Enhanced Intel SpeedStep(EIST), Thermal Monitor 2(TM2), C-states C0 to C4, and adds C6 "Deep Power Down Technology".
Certain Silverthorne chips feature Burst Mode Technology, which is different from Turbo Mode that it only relies on temperature and power consumption, while Turbo Mode is mostly guaranteed and is based on number of cores active. Of course, Silverthorne only has 1 core.
Netbook Diamondville doesn't have C6, but everything else. Nettop Diamondville forgoes EIST and TM entirely.
Diamondville is a 3 chip solution consisting of CPU, GMCH and ICH, while Silverthorne has the GMCH and ICH combined as a companion chip called Poulsbo. Platform TDP is 33W+ on Nettop, on Netbook its ~9W for SC and 13W for DC for Diamondville. For Menlow it can be as low as 2.2W, and high as 4.7W. Most lie at 4.4W.
Diamondville clocks: 1.6GHz-1.86GHz
Silverthorne clocks: 800MHz-2.13GHz
Major products: Netbooks and Nettops for Diamondville, MID/UMPCs, and Netbooks for Silverthorne, mid-2008
Pineview-
Pineview integrates Graphics and Memory Controller Hub(GMCH) onto the CPU. The CPU talks to the GMCH via a low bandwidth internal bus, and to the I/O chip using DMI. Platform TDP is Netbook=7W SC/10W DC, Nettop=12.2W SC/15.2W DC. Supports DDR2, and DDR3 with updated SKUs. Single channel 64-bit.
Platform code name is Pine Trail. EIST/C4E supported.
Clocks: 1.5GHz-1.86GHz
Major products: Netbooks and Nettops, Dec 20, 2009
Lincroft-
Lincroft takes the GMCH from Poulsbo to the CPU. The Moorestown platform allows Smartphone and Tablet market entrance for Intel. There is also the Brierstown PMIC(Power Management IC), and the Evans Peak wireless chips. Lower power SKUs support 32-bit single channel LPDDR with 400MT/s while others feature LPDDR2 at 800MT/s. Lincroft+Langwell Platform level TDP is 1.8W(Add 0.3W for Hyperthreading), and 2.7W(Add 0.35W for Hyperthreading, 0.45W ODT) for Moorestown(non-Windows Smartphone/Tablet versions) and 3.5W for Oak Trail(Windows Tablets). PowerVR SGX535 @ 400MHz allows some HD video playback, though it doesn't seem to be too optimal at this point. Camera support is 5MP.
Uses OS Power Management(OSPM) to save power and manage performance. Burst Mode supported in most SKUs. Moorestown does not support desktop Windows because it lacks legacy components and ACPI/PCI/SATA. Oak Trail supports Windows.
Oak Trail Specific: Oak Trail is a very close cousin to Queens Bay/Tunnel Creek but has some similarities with Moorestown/Lincroft. It can be seen as Windows-capable version of Moorestown and a spiritual successor to Menlow platform. It uses DMI rather than PCI Express to save power. Legacy components means higher power than Moorestown.
Platform code name is Moorestown for the non Windows supporting version and Oak Trail for the Windows supporting one. EIST/C6 supported, S0ix on Moorestown.
Clocks: 600MHz to 1.9GHz(in Burst Mode) for Moorestown
1.5GHz for Oak Trail
Major products: Cisco Cius featured Moorestown, while few Windows Tablets used Oak Trail. Moorestown announced May 4, 2010. Oak Trail announced Apr 7, 2011
Sodaville-
This is a TRUE SoC, and only one at the moment. The single die has the Atom CPU, NAND controller, GMCH, Transport and Security processor, Dual Audio DSP, General and Audio/Video I/O. It can decode two 1080p video and audio streams. Platform TDP 7-9W. Sodaville does not feature EIST and most C/P states, even STR(Suspend to RAM), which is available in most modern CPUs(if not all).
Clocks: 1.2GHz
Major products: Google TV, Boxee Box, other Internet TV appliances, silicon availability late 2009, product available since 2010.
Tunnel Creek-
The platform consists of two chips. The Tunnel Creek features CPU core, GMCH, Audio and PCI Express controller.
Unlike the other Atom CPUs that use DMI, it uses the PCI Express link to talk to the companion chips. The companion chip can be a plain vanilla Intel chip, or can be substituted for 3rd party chip. Platform level TDP will be 4.2-5.4W.
Platform code name is Queens Bay. Same power management as Oak Trail.
Clocks: 600MHz to 1.6GHz
Major products: Embedded Atom for industrial applications needing low power. In-car infotainment from a company in China, and wireless infrastructure for China Mobile. Announced September 14, 2010, products shortly after.
Stellarton
This is a configurable Atom platform using Tunnel Creek CPU component and a FPGA from Altera in an MCM package. Launched November 22, 2010 as Atom E600C, products shortly after.
Same power management as Tunnel Creek. Other than the Altera FPGA, its the same chip.
Groveland-
This is a successor to Sodaville. Adds STR, power gating, clock gating and other power management goodies. Includes power management IC and H.264 Encoder support. Products expected sometime in 2012.
Clocks: 1.2-1.6GHz
Cedarview-
32nm Successor to Pine Trail. Unlike the predecessor it supports C6 to lower power usage. It features PowerVR SGX545, with high clock of 400/640MHz depending on power levels. Improved 1080p decoding over Oak Trail. TDP is lot lower on the CPU side(especially the Netbook version), though it uses the same NM10 chipset as Pine Trail. 5W/8W platform TDP for Netbooks, 12.2W/15.2W for Nettops.
Clocks: 1.6-2.13GHz
Platform code name is Cedar Trail. Supports EIST/C6.
Major Products: Netbooks and Nettops. December 28, 2011 the product was announced. Product availability early 2012.
Penwell-
32nm successor to Moorestown. Said to integrate Lincroft and Langwell into one chip. First Intel chip with PoP(Package on Package) LPDDR2 memory. Avantele Passage SoC is for MSIC(Mixed Signal IC). Dual 32-bit memory interface with 800MT/s. Better 3D performance and video playback(1080p/Encoding). Features an Image Processing unit from Intel owned Silicon Hive. Features hardware security IP that might be collaboration from Intel owned McAfee. Supports Camera resolutions more than 3x Moorestown(16MP). SoC and platform level power usage seems to be less than half the power of the predecessor. Internal interconnect possibly made to easily add 3rd party IP. Medfield platform does not run Windows. Android is now the lead OS.
Mid-range Atom comes first with low end later in 2012 and dual core with updated graphics in 2013.
The fallout in the Intel-TSMC deal means that Intel will be allowing 3rd party vendors to add their IP to future Atom cores. The embedded versions and smartphone versions will be impacted the largest by this.
Cloverview/Clover Trail specific: This is the Windows supporting version of Medfield. Dual cores are expected, though it wouldn't be surprising if single cores are there too. Expected launch with Windows 8 late this year. Power usage will likely be higher than Medfield, though still very low power.
Platform code name Medfield. Supports EIST, C6, S0ix power management features. Platform code name is Clover Trail for Windows supporting version. Medfield does not support Windows.
Clocks: 1GHz-2GHz(Burst Mode included)
Major products: Smartphones and next generation Tablets. Nokia deal fell off and at CES 2012 Motorola and Lenovo announced partnerships. Products in mid 2012. Dual cores later.
Tangiere-
22nm successor to Penwell.
Berryville-
32nm successor to Groveland. Enables Hyperthreading and there are dual core variants. Adds a feature called PQE or Picture Quality engine. Better cost optimized with more integration than previous generation.
Clocks: 1.2-1.8GHz
Valleyview-
22nm successor to Cedarview. It's said to have a revised CPU architecture and the graphics is a derivative of Ivy Bridge.
Airmont-
No details on platform code name. Airmont is a 14nm Atom core.
