Snapdragon is a series of systems on chip semiconductor products (SoCs) for mobile devices designed and marketed by Qualcomm Technologies Inc. Snapdragon central processing unit (CPU) uses the ARM RISC instruction set, and one SoC can include multiple CPU cores, graphics processing units (GPUs), wireless modems, and other software and hardware to support the global GPS (GPS) introduction of movement and video from smartphone. The Snapdragon semiconductor is embedded in various system devices, including Android and Windows Phone devices. They are also used for netbooks, in cars, usable devices and other devices. In addition to processors, Snapdragon lines include modems, wi-fi chips and mobile phone charging products.
The first Snapdragon product made for consumer device manufacturers is the QSD8250, which was released in November 2007. It includes the first 1 GHz processor for mobile phones. Qualcomm introduced the "Krait" microarchitecture of the second generation Snapdragon SoCs in 2011, allowing each processor core to adjust its speed according to device requirements. At the Consumer Electronics Show 2013, Qualcomm introduced the first of the Snapdragon 800 series and renamed the previous models as the 200, 400, and 600 series. Several new iterations have been introduced since, such as Snapdragon 805, 810, 615 and 410. Qualcomm re-branded its modem products under the name Snapdragon in December 2014.

History
Pre-release
Qualcomm announced it was developing a Scorpion central processing unit (CPU) in November 2007. The Snapdragon on chip system (SoC) was announced in November 2006 and included Scorpion processors, as well as other semiconductors. It also includes the first DSP custom HSPagon (DSP) digital signal processor (DSP).
According to a Qualcomm spokesman, it's named Snapdragon, because "Snap and Dragon sounds fast and fierce." The following month, Qualcomm acquired Airgo Networks for an undisclosed amount; it is said that Wi-Fi 802.11a/b/g and 802.11n Airgo technology will be integrated with Snapdragon products. Early versions of Scorpion have a core design processor similar to the Cortex-A8.
Initial product
The first Snapdragon delivery was QSD8250 in November 2007. According to CNET, Snapdragon's claim to fame was to have the first 1 GHz mobile processor. Most of the smartphones were using the 500Ã, MHz processor. The first generation of Snapdragon products supports 720p resolution, 3D graphics, and a 12 megapixel camera. In November 2008, 15 device manufacturers decided to embed semiconductor Snapdragon in their consumer electronics products.
In November 2008, Qualcomm announced that it will also compete with Intel in the netbook processor market with a dual-core Snapdragon system planned for the end of 2009. It shows Snapdragon processors that consume less power than Intel chips announced around the same time and claiming it would also be cheaper when released. In the same month, Qualcomm introduced a prototype-based Snapdragon netbook called Kayak that uses a 1.5 GHz processor and is intended for emerging markets.
In May 2009, Java SE was ported and optimized for Snapdragon. At the Computex Taipei show in November 2009, Qualcomm announced the addition of QSD8650A to Snapdragon products, based on a 45 nanometer manufacturing process. It features a 1.2 GHz processor and has lower power consumption than previous models.
Adoption
At the end of 2009, smartphone manufacturers announced they will use Snapdragon SoCs on Acer Liquid Metal, HTC HD2, Toshiba TG01 and Sony Ericsson Xperia X10. Lenovo announced its first netbook product using Snapdragon SoCs in December. According to PC World , mobile devices that use Snapdragon have better battery life and are smaller in size than those using other SoCs.
As of June 2010, the Snapdragon chip is embedded in 20 consumer devices available and incorporated into 120 product designs in development. 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 is therefore relying on competing Android phones, such as Google Nexus One and HTC Incredible, challenging Apple's market position. Android devices are finally taking market share from iPhone and mostly using Snapdragon.
There are "unconfirmed but widely circulated reports" that speculate that Apple will start using Snapdragon SoCs on Verizon's iPhone-based. In 2012, Apple is still using their own Ax design semiconductor. Support for Windows Phone 7 operating system added to Snapdragon in October 2010.
In 2011 Snapdragon is embedded in Hewlett Packard WebOS devices and has a 50% market share of the $ 7.9 billion smartphone processor market. In 2012, Snapdragon S4 (Krait core) has taken the dominant share of other Android on-chip systems such as Nvidia Tegra and Texas Instruments OMAP which caused the latter to exit the market. As of July 2014, Android phone market share has increased to 84.6 percent, and Qualcomm's Snapdragon chip is embedded in 41% of smart phones. However, in September 2013, the debut of the Apple A7 64-bit chip on the iPhone 5S forced Qualcomm to release competing 64-bit products, despite the capable Snapdragon 800/801/805 performance, due to their existing Krait core of only 32- few. The first 64-bit SoCs, Snapdragon 808 and 810, rushed into the market using the generic Cortex-A57 and Cortex-A53 cores and suffered from overheating and throttling problems, especially the 810, which caused Samsung to stop using Snapdragon for its flagship Galaxy S6 phone.
The Snapdragon chip is also used in most Android-based smartwatch. Snapdragon products have also been used in virtual reality products, in vehicles such as Maserati Quattroporte and Cadillac XTS and in other applications.
Next model
In June 2010, Qualcomm began taking samples of third-generation Snapdragon products; two 1,2-GHz dual-core systems on chip (SoC) are called Mobile Station Modem (MSM) 8260 and 8660. 8260 is for GSM, UMTS and HSPA networks, while 8660 for CDMA2000 and EVDO networks. That November Qualcomm announced MSM8960 for the LTE network.
In early 2011, Qualcomm announced a new processor architecture called Krait, which uses the ARM v7 instruction set, but is based on Qualcomm's own processor design. The processor is called S4 and has a feature called Asynchronous Symmetrical Multi-Processing (aSMP), which means each processor core adjusts its clock speed and voltage based on device activity to optimize battery usage. The previous model was renamed to S1, S2 and S3 to distinguish each generation.
The S4 Snapdragon So4 generation is being delivered to the product manufacturer with MSM8960 in February 2012. In the benchmark test by Anandtech, MSM8960 performs better than any other processor being tested. In the overall system benchmark, 8960 scored 907, compared with 528 and 658 for Galaxy Nexus and HTC Rezound. In the Quadrant benchmark test, which assesses the processing power of crude, the dual-core Krait processor has a score of 4752, while the quad-core Tegra 3 is just under 4,000. The quad-core version, APQ8064, was made available in July 2012. This is the first Sncdragon SoC to use Adreno 320 (GPU) Qualcomm graphics processing unit.
The Snapdragon adoption contributes to Qualcomm's transition from wireless modem companies to one that also generates more hardware and software for mobile devices. In July 2011 Qualcomm acquired certain assets of GestureTek to incorporate intellectual property recognition of its movements into Snapdragon SoCs. In mid-2012, Qualcomm announced the Snapdragon software development kit (SDK) for Android devices at the developer conference Uplinq. The SDK includes tools for face recognition, motion recognition, noise cancellation and audio recording. In November, Qualcomm acquired several assets from EPOS Development to integrate stylus and gesture recognition technologies into Snapdragon products. It also collaborated with Microsoft to optimize Windows Phone 8 for the Snapdragon semiconductor.
In 2012, Snapdragon S4 (Krait core) has taken the dominant share of other Android on-chip systems such as Nvidia Tegra and Texas Instruments OMAP which caused the latter to exit the market. As of July 2014, Android phone market share has increased to 84.6 percent, and Qualcomm's Snapdragon chip supports 41 percent of smartphones.
However, in September 2013, the debut of Apple's 64-bit A7 chip on the iPhone 5S forced Qualcomm to issue a competing 64-bit solution, despite the qualified Snapdragon 800/801/805 performance, as their existing Krait core was only 32-bit. The first 64-bit SoCs, Snapdragon 808 and 810, were thrown into the market using the generic Cortex-A57 and Cortex-A53 cores and suffered overheating and throttling problems, especially the 810, which led to Samsung ditching Snapdragon for its flagship Galaxy S6 phone.
The entry-level 200 series is expanded with six new processors using 28 nanometer manufacturing and dual or quad-core options in June 2013. Snapdragon 210 entry level, intended for low-cost phones, was announced in September 2014. Snapdragon 820, with 64-bit Kyro core in -home, mostly solve the performance and heat problem of Snapdragon 810.
Recent developments
Qualcomm announced the Snapdragon 835 SoC on November 17, 2016, to be built by Samsung using the 10-nanometer FinFET process. The new processor will have 30 percent more parts in the same space and will have a 27 percent better performance with 40 percent less power. Because of Samsung's role in chip making, its mobile division also earned an initial supply of chips. This means no other OEMs can produce products containing 835 until the release of Samsung's next flagship device, Galaxy S8.
At Computex 2017 in May, Qualcomm and Microsoft announced plans to launch a Snapdragon-based laptop running Windows 10. It partnered with HP, Lenovo, and Asus to unleash the sleek portability and 2-in-1 devices supported by Snapdragon 835. In the month December 2017, Qualcomm announced 845. It has a 10-nanometer manufacturing process similar to other products in the 800 series but introduces a new processor architecture designed for better battery life, photography, and for use with artificial intelligence applications. According to Qualcomm, it has a performance 25-30 percent faster than the 835. In early 2018, Qualcomm introduced 700, which was between 600 and 800 in terms of price and performance.

Description and current model
Snapdragon systems on chip products typically include graphics processing units (GPUs), global positioning systems (GPS) and cellular modems integrated into one package. It has software included that operates graphics, video and image capture. There are 19 different Snapdragon processors under 400, 600 and 800 family products that stretch from low to high end respectively, as well as wi-fi and mobile phone charging products. Some of their components include Adreno graphics processing, Qualcomm Hexagon DSP and processors using Qualcomm's S4 processor architecture. In addition to smartphones, the 400 series is used in smart watches and the 602A is intended for electronics in cars.
The Snapdragon naming scheme is currently implemented after the Snapdragon 800 family was announced at the 2013 Consumer Electronics Show; the previous model was renamed to the 200, 400, or 600 series. The new 600 Snapdragon is also released, which is mid-year embedded in most of the new Android devices. The 400 family is entry-level, 600 is mass-market or mid-range, and 800 families are for high-end or flagship phones.
Snapdragon 805 was released in November. The 410, aimed at cheap phones in the developing world, was announced the following month. In January 2014, Qualcomm introduced a modified version of Snapdragon 600 called 602A aimed at in-car infotainment screens, backup cameras, and other driver assistance products. The 610 and eight-core 615 quad-core snap-core was announced in February 2014. Snapdragon 808 and 810 were announced in April 2014. Snapdragon 835, announced in November 2017, is the first Qualcomm SOC built on 10 nm architecture. Qualcomm's new flagship chip for 2018, 845, announced in December 2017. According to Qualcomm, 845 is 25-30% faster than the 835.
In February 2015, Qualcomm re-branded stand-alone modem products under the name Snapdragon; they are distinguished from SoC using "x" tagging, such as X7 or X12 modems. The first Snapdragon modem for the 5G network, the X50, was announced at the end of 2016. This was followed by a 2GB X24 modem on the 7 nanometer manufacturing process announced in February 2018.
According to CNET, this phone grew in US market share and ranked high in CNET reviews due to their response. Snapdragon SoCs are also used in most Windows phones and most phones are coming into the market in mid 2013. LG G2 is the first phone to market using Snapdragon 800 in August 2013.
In 2017, 660 and 630 replaced the mid-range models of 653 and 626 and some chips in the family's 400 products have been revitalized. In February 2017, Qualcomm introduced Snapdragon X20, aimed at 5G mobile phone networks, and two new chips for the 802.11ax commercial wi-fi network. This was followed by the addition of 636 for the October 600 product family, which Qualcomm said would be 40 percent faster than the 630.
Test benchmark
The benchmark test of the Snapdragon 800 processor by PC Magazine found that its processing power is comparable to that of Nvidia. The Snapdragon 805 Benchmark found that the Adreno 420 GPU resulted in a 40 percent increase in graphics processing through the Adreno 330 in Snapdragon 800, although there were only slight differences in the processor benchmark. The level of the Snapdragon 801 inside HTC One finds a "bump around" in benchmark improvements above 800. By 2015, Samsung's decision not to use Snapdragon 810 on the Galaxy S6 has a significant detrimental impact on Snapdragon revenue and reputation. Benchmark tests by Ars Technica confirm rumors that 810 low-end models are done low and have overheating problems. A Qualcomm spokesman said the test was conducted with an early version of 810 that was not ready for commercial use. The latest version was released and found to be enough to increase thermal throttling, GPU clock speed, memory latency, and memory bandwidth when tested in commercial products, Xiaomi Mi Note Pro. In addition, 835 and 845 are followed performing much better.
