Snapdragon is a suite ofsystem-on-chip (SoC)semiconductor products formobile devices designed and marketed byQualcomm, who often refers to these SoCs as "mobile platforms". They typically integratecentral processing units (CPU) based on theARM architecture, agraphics processing unit (GPU), somedigital signal processors (DSP), and may or may not include acellular modem. Snapdragon semiconductors are designed forembedded systems, e.g.,smartphones,netbooks, and vehicles.[1] In addition to the processors, the lineup also includes modems,Wi-Fi chips and mobile charging products.
The first Snapdragon-branded product was released in December 2007, using CPU based on Qualcomm’s “Scorpion”microarchitecture. The architecture’s successor, “Krait”, was introduced in 2011 and featuredasynchronoussymmetrical multi-processing: cores can adjust their clock speed and voltage independent to each other.[2] On the announcement of Snapdragon 800 in 2013Consumer Electronics Show, Qualcomm renamed their prior models to the 200, 400 and 600 series. Qualcomm re-branded its modem products under the Snapdragon name in February 2015.

Qualcomm announced it was developing theScorpion central processing unit (CPU) in November 2007.[3][4] The Snapdragon system on chip (SoC) was announced in November 2006 and included the Scorpion processor, as well as other semiconductors.[4][5] This also included Qualcomm's first customHexagondigital signal processor (DSP).[6]
According to a Qualcomm spokesperson, it was named Snapdragon, because "Snap and Dragon sounded fast and fierce."[7] The following month, Qualcomm acquiredAirgo Networks for an undisclosed amount; it said Airgo's 802.11a/b/g and 802.11n Wi-Fi technology would be integrated with the Snapdragon product suite.[8][9] Early versions of Scorpion had a processor core design similar to theCortex-A8.[4]
The first Snapdragon was released in November 2007. CNET noted its relatively high 1 GHz CPU clock speed as the product's "claim to fame", when contemporary smartphone processors are commonly using 500 MHz CPU.[10][11] The product can output display at up to720p resolution, render 3D graphics, and supports a up-to 12-megapixel camera.[10][12] By November 2008, 15 device manufacturers had embed Snapdragon chips in their consumer electronics products.[13][14][15]
In November 2008, atechdemo processor and netbook was showcased. The processor consumed less power than the contemporary IntelAtomZ500 and was claimed to be more cost-effective when released.[16][17][18] The netbook used 1.5 GHz processors and was intended for developing markets.[14][19][20]
In collaboration withSun,Java SE received Snapdragon-specific optimizations in May 2009.[21] Qualcomm started using45nm process for SoC productions in late 2009.[22][23]
By June 2010, Snapdragon chips were incorporated into 120 product designs in development.[24] The company announced the MSM8960[25][26] for LTE networks that November.[27]
Apple had a dominant market position for smartphones at the time and did not incorporate Snapdragon into any of its products. The success of Snapdragon therefore relied on competingAndroid phones.[24][28][29][30]
Support for theWindows Phone 7 operating systems was added to Snapdragon in October 2010.[29]
By 2011 Snapdragon was embedded inHewlett Packard's WebOS devices[31] and had a 50% market share of a $7.9 billion smartphone processor market.[clarification needed][32]
As of July 2014 Qualcomm's Snapdragon chips were embedded in 41% of smartphones.[33]
Snapdragon chips are also used in Android-based smartwatches,[34] and in vehicles like theMaserati Quattroporte andCadillac XTS.[35]
In early 2011, Qualcomm announced Krait,[36] an in-house CPU microarchitecture design supporting the ARM v7 instruction set. SoCs featuring Krait were named S4 supportsasynchronoussymmetrical multi-processing (aSMP), meaning each processor core adjusted its clock speed and voltage based on the device's activity in order to optimize battery usage.[2] Prior models were renamed to S1, S2 and S3 to distinguish between each generation.[37]
The S4-based generation of Snapdragon SoCs began shipping to product manufacturers with the MSM8960 in February 2012.[38] In benchmark tests byAnandtech, the MSM8960 had better performance than any other processor tested. In an overall system benchmark, the 8960 obtained a score of 907, compared to 528 and 658 for theGalaxy Nexus andHTC Rezound respectively.[39] In a Quadrant benchmark test, which assesses raw processing power, a dual-core Krait processor had a score of 4,952, whereas the quad-coreTegra 3 was just under 4,000.[40] The quad-core version, APQ8064, was made available in July 2012. It was the first Snapdragon SoC to use Qualcomm's Adreno 320 graphics processing unit (GPU).[41]
Adoption of Snapdragon contributed to Qualcomm's transition from a wireless modem company to one that also produces a wider range of hardware and software for mobile devices.[42] In July 2011 Qualcomm acquired certain assets fromGestureTek in order to incorporate its gesture recognition intellectual property into Snapdragon SoCs.[43] In mid-2012 Qualcomm announced the Snapdragon software development kit (SDK) for Android devices at the Uplinq developer conference.[44] The SDK includes tools for facial recognition, gesture recognition, noise cancellation and audio recording.[44] That November Qualcomm acquired some assets from EPOS Development in order to integrate its stylus and gesture recognition technology into Snapdragon products.[45] It also collaborated withMicrosoft to optimizeWindows Phone 8 for Snapdragon semiconductors.[46]
By 2012, the Snapdragon S4 (Krait core) had taken a dominant share from other Android system-on-chips likeNvidia Tegra andTexas Instruments OMAP which caused the latter to exit the market.[47] As of July 2014, the market share of Android phones had grown to 84.6 percent,[48] and Qualcomm's Snapdragon chips powered 41% of smartphones.[33]
Snapdragon SoCs are also used in most Windows phones[46] and most phones entering the market in mid-2013.[49]
