Bonnell is a CPU microarchitecture used by Intel Atom processors which can execute up to two instructions per cycle. Like many other x86 microprocessors, it translates x86 instructions ( CISC instructions) into simpler internal operations (sometimes referred to as micro-ops , effectively RISC style instructions) prior to execution. The majority of instructions produce one micro-op when translated, with around 4% of instructions used in typical programs producing multiple micro-ops. The number of instructions that produce more than one micro-op is significantly fewer than the P6 and NetBurst microarchitectures . In the Bonnell microarchitecture, internal micro-ops can contain both a memory load and a memory store in connection with an ALU operation, thus being more similar to the x86 level and more powerful than the micro-ops used in previous designs. This enables relatively good performance with only two integer ALUs, and without any instruction reordering , speculative execution or register renaming . A side effect of having no speculative execution is invulnerability against Meltdown and Spectre .

52-419: The Bonnell microarchitecture therefore represents a partial revival of the principles used in earlier Intel designs such as P5 and the i486 , with the sole purpose of enhancing the performance per watt ratio. However, Hyper-Threading is implemented in an easy (i.e. low-power) way to employ the whole pipeline efficiently by avoiding the typical single thread dependencies. On 2 March 2008, Intel announced

104-576: A 945GSE or US15W chipset and an Atom N270, N280 or Z5xx series CPU. On 21 December 2009, Intel announced the N450, D510 and D410 CPUs with integrated graphics. The new manufacturing process resulted in a 20% reduction in power consumption and a 60% smaller die size. The Intel GMA 3150 , a 45 nm shrink of the GMA 3100 with no HD capabilities, is included as the on-die GPU. Netbooks using this new processor were released on 11 January 2010. The major new feature

156-413: A clock speed of 1.66 GHz and a 667 MHz FSB. On 22 September 2008, Intel announced a new 64-bit dual-core processor (unofficially code-named Dual Diamondville) branded Atom 330, to be used in desktop computers. It runs at 1.6 GHz and has an FSB speed of 533 MHz and a TDP rating of 8 W. Its dual core consists of two Diamondville dies on a single substrate. During 2009, Nvidia used

208-501: A line of netBook products that was later released in 1999. International trademarks were issued (including U.S. Trademark 75,215,401 and EUTM 000428250 ) but the models failed to gain popularity and are now discontinued (except for providing accessories, maintenance and support to existing users). Similar marks were recently rejected by the USPTO citing a "likelihood of confusion" under section 2(d). Despite expert analysis that

260-547: A more power-efficient 2-chip platform rather than the 3-chip one used with previous-generation Atom chipsets. On 1 March 2010, Intel introduced the N470 processor, running at 1.83 GHz with a 667 MHz FSB and a TDP rating of 6.5 W. The new Atom N4xx chips became available on 11 January 2010. It is used in netbook and nettop systems and includes an integrated single-channel DDR2 memory controller and an integrated graphics core . It also features Hyper-Threading and

312-465: A netbook running OS X a " Hackintosh ." A June 2009 NPD study found that 60% of netbook buyers never take their netbooks out of the house. Special "children's" editions of netbooks have been released under Disney branding; their low cost (less at risk), lack of DVD player (less to break) and smaller keyboards (closer to children's hand sizes) are viewed as significant advantages for that target market. The principal objection to netbooks in this context

364-634: A new market segment for Windows devices, whilst ensuring that the devices did not cannibalize the sales of higher-end PCs running Windows Vista . In 2009, over 90% (96% claimed by Microsoft as of February 2009) of netbooks in the United States were estimated to ship with Windows XP. For Windows 7 , Microsoft introduced a new stripped-down edition intended for netbooks known as "Starter", exclusively for OEMs. In comparison to Home Premium, Starter has reduced multimedia functionality, does not allow users to change their desktop wallpaper or theme, disables

416-415: A new single-core Atom Z5xx series processor (code-named Silverthorne), to be used in ultra-mobile PCs and mobile Internet devices (MIDs), which will supersede Stealey (A100 and A110). The processor has 47 million transistors on a 25 mm die, allowing for extremely economical production at that time (~2500 chips on a single 300 mm diameter wafer). An Atom Z500 processor's dual-thread performance

468-514: A screen size of about 10 inches, intended primarily for media consumption and light productivity." Although some manufacturers directly blamed competition from the iPad, some analysts pointed out that larger, fully fledged laptops had entered the price range of netbooks at about the same time. The 11.6-inch MacBook Air , introduced in late 2010, compared favorably to many netbooks in terms of processing power but also ergonomics, at 2.3 pounds being lighter than some 10-inch netbooks, owing in part to

520-573: A simplified user interface geared towards consumer use. Following the Eee PC, Everex launched its Linux-based CloudBook ; Windows XP and Windows Vista models were also introduced and MSI released the Wind —others soon followed suit. The OLPC project followed the same market goals laid down by the eMate 300 eight years earlier. Known for its innovation in producing a durable, cost- and power-efficient netbook for developing countries , it

572-941: A traditional desktop interface and a platform allowing "native" packaged software written in HTML , JavaScript , and CSS to be developed for the platform. Netbooks have sparked the development of several Linux variants or completely new distributions, which are optimized for small screen use and the limited processing power of the Atom or ARM processors which typically power netbooks. Examples include Ubuntu Netbook Edition , EasyPeasy , Joli OS and MeeGo . Both Joli OS and MeeGo purport to be "social oriented" or social networking operating systems rather than traditional "office work production" operating systems. Netbook users can also install other UNIX-based operating systems such as FreeBSD , NetBSD , OpenBSD , and Darwin . Since 2010, major netbook manufacturers no longer install or support Linux in

624-551: A typical weight of about 1 kg ( 2.2 pounds ), and were often significantly less expensive than other laptops . Soon after their appearance, netbooks grew in size and features, and converged with smaller laptops and subnotebooks until the specifications were so similar that there was little distinction between the devices. At their peak, the low cost gave them a significant portion of the laptop computer market. When Windows 7 released, netbook manufacturers had to increase specifications in order for their devices to run it. This had

Intel's Pine Trail-M platform utilizes an Atom processor (codenamed Pineview-M) and Platform Controller Hub (codenamed Tiger Point). The graphics and memory controller have moved into the processor, which is paired with the Tiger Point PCH. This creates

988-435: Is manufactured on a 45 nm process. The new design uses half the power of the older Menlow platform. This reduced overall power consumption and size makes the platform more desirable for use in smartphones and other mobile internet devices. The D4xx and D5xx series support the x86-64 bit instruction set and DDR2-800 memory. They are rated for embedded use. The series has an integrated graphics processor built directly into

1040-481: Is now facing competition. Developing countries now have a large choice of vendors, from which they can choose which low-cost netbook they prefer. By late 2008, netbooks began to take market share away from notebooks . It was more successful than earlier "mini notebooks," most likely because of lower cost and greater compatibility with mainstream laptops. Having peaked at about 20% of the portable computer market, netbooks started to slightly lose market share (within

1092-494: Is regarded as one of the major factors that led more top computer hardware manufacturers to begin creating low-cost netbooks for the consumer market. When the first Asus Eee PC sold over 300,000 units in four months, companies such as Dell and Acer took note and began producing their own inexpensive netbooks. And while the OLPC XO-1 targets a different audience than do the other manufacturers' netbooks, it appears that OLPC

1144-544: Is the lack of good video performance for streaming online video in current netbooks and a lack of speed with even simple games. Adults browsing for text content are less dependent on video content than small children who cannot read. Netbooks offer several distinct advantages in educational settings. First, their compact size and weight make for an easy fit in student work areas. Similarly, their small size makes netbooks easier to transport than heavier, larger sized traditional laptops. In addition, prices ranging from $ 200–$ 600 mean

1196-504: The Intel Atom line, but some used competing processors from AMD , including netbook APUs , or VIA Technologies , including the C7 and Nano . Some very low-cost netbooks use a system-on-a-chip Vortex86 processor designed for embedded systems . A few netbooks used non-x86 processors based on ARM or MIPS architectures. Microsoft announced on April 8, 2008, that, despite

For Windows 8 , in a ploy to counter ChromeOS -based netbooks and low-end Android tablets, Microsoft began to offer no-cost Windows licenses to OEMs for devices with screens smaller than 9 inches in size. Additionally, Microsoft began to offer low-cost licenses for a variant of the operating system set up to use Microsoft's Bing search engine by default. Windows CE has also been used in netbooks, due to its reduced feature set. Google's Android software platform, designed for mobile telephone handsets, has been demonstrated on an ASUS Eee PC and its version of

1300-536: The "Digital Classroom Initiative". Students were given one unique coupon each, with which they redeemed the netbook of their choice, up to a €450 price ceiling, in participating shops throughout the country. These netbooks came bundled with localized versions of either Windows XP (or higher) or open source (e.g. Linux ) operating systems, wired and wireless networking functionality, antivirus protection, preactivated parental controls, and an educational software package. In 1996 Psion started applying for trademarks for

1352-474: The 945GSE Express chipset has a specified maximum TDP of 11.8 W, with the processor responsible for a relatively small portion of the total power dissipated. Individual figures are 2.5 W for the N270 processor, 6 W for the 945GSE chipset and 3.3 W for the 82801GBM I/O controller.

1664-447: The United States. The reason for this change of stance is unclear, although it coincides with the availability of a 'netbook' version of Windows XP, and a later Windows 7 Starter and a strong marketing push for the adoption of this OS in the netbook market. However, companies targeting niche markets, such as System76 and ZaReason, continue to pre-install Linux on the devices they sell. The Cloud operating system attempted to capitalize on

1716-572: The average netbook, as much as three or four times more. In 2011 tablet sales overtook netbooks for the first time, and in 2012 netbook sales fell by 25 percent, year-on-year. The sustained decline since 2010 had been most pronounced in the United States and in Western Europe, while Latin America was still showing some modest growth. In December 2011, Dell announced that it was exiting the netbook market. In May 2012, Toshiba announced it

1768-491: The basis of abandonment, genericness and fraud. They later revealed Psion's counter-suit against Intel , filed on February 27, 2009. It was also revealed around the same time that Intel had also sued Psion Teklogix (US & Canada) and Psion (UK) in the Federal Court on similar grounds. In addition to seeking cancellation of the trademark, Intel sought an order enjoining Psion from asserting any trademark rights in

1820-476: The category) in early 2010, coinciding with the appearance and success of the iPad . Technology commentator Ross Rubin argued two and a half years later in Engadget that "Netbooks never got any respect. While Steve Jobs rebuked the netbook at the iPad's introduction, the iPad owes a bit of debt to the little laptops. The netbook demonstrated the potential of an inexpensive, portable second computing device, with

1872-414: The effect of pushing netbooks into a market niche where they had few distinctive advantages over traditional laptops. With these constraints and the increasing popularity of tablet computers in 2011, it led to declining sales of netbooks. By the end of 2012, few new laptops were marketed as "netbooks", and the term disappeared from common usage. While Psion had unrelated netBook line of machines,

1924-401: The fourth quarter of 2011. Intel stated that improvements in graphics capabilities, including support for 1080p video, additional display options including HDMI and DisplayPort, and enhancements in power consumption are to enable fanless designs with longer battery life.

The move served primarily to counter the use of low-cost Linux distributions on netbooks and create

2028-405: The integration of the flash storage chips on the main logic board. It was described as a superlative netbook (or at least as what a netbook should be) by several technology commentators, even though Apple has never referred to it as such, sometimes describing it—in the words of Steve Jobs —as "the third kind of notebook." The entry-level model had a MSRP of $ 999, costing significantly more than

2080-466: The introduction of Chromebooks , major manufacturers produced the new laptops for the same segment of the market that netbooks serviced. Chromebooks, a variation on the network computer concept, in the form of a netbook, require internet connections for full functionality. Chromebooks became top selling laptops in 2014. The threat of Google ChromeOS based Chromebooks prompted Microsoft to revive and revamp netbooks with Windows 8.1 with Bing . HP re-entered

2132-592: The mark is "probably generic ", Psion Teklogix issued cease and desist letters on December 23, 2008. This was heavily criticized, prompting the formation of the "Save the Netbooks" grassroots campaign which worked to reverse the Google AdWords ban, cancel the trademark and encourage continued generic use of the term. While preparing a "Petition for Cancellation" of U.S. Trademark 75,215,401 they revealed that Dell had submitted one day before on

In addition to the netbook platform, two new Cedarview CPUs for nettops, D2500 and D2700, were released on 25 September 2011. In early March 2012, the N2800-based Intel DN2800MT motherboard started to become available. Due to the use of a netbook processor, this Mini-ITX motherboard can reach idle power consumption as low as 7.1 W. Penwell

2392-550: The term "netbook", a declarative judgment regarding their use of the term, attorneys' fees, costs and disbursements and "such other and further relief as the Court deems just and proper". On June 2, 2009, Psion announced that the suit had been settled out of court. Psion's statement said that the company was withdrawing all of its trademark registrations for the term "Netbook" and that Psion agreed to "waive all its rights against third parties in respect of past, current or future use" of

2444-832: The term. Netbooks typically have less powerful hardware than larger laptop computers and do not include an optical disc drive that contemporaneous laptop computers often had. Netbooks were some of the first machines to substitute solid-state storage devices, instead of the traditional hard disk drive commonly found on laptop and desktop computers at the time. This was due to solid-state drives being smaller, more power efficient, and more shock resistant. Unlike modern solid-state drives, these early models often did not offer better performance. Almost all netbooks supported Wi-Fi and some supported Mobile broadband . Some also include Ethernet and/or modems . Most netbooks used low-end, x86 processors focused on low power consumption. The majority of early netbooks typically used processors from

2496-478: The use of the broad marketing term "netbook", began in 2007 when Asus unveiled the Asus Eee PC . Originally designed for emerging markets, the 23 cm × 17 cm (9.1 in × 6.7 in) device weighed about 0.9 kg (2 lb) and featured a 7 in (18 cm) display, a keyboard approximately 85% the size of a normal keyboard, a solid-state drive and a custom version of Linux with

2548-508: The x86 platform, especially for netbooks. In 2011, Google introduced ChromeOS , a Linux-based operating system designed particularly for netbook-like devices marketed as " Chromebooks ". The platform is designed to leverage online services, cloud computing , and its namesake Chrome web browser as its shell —so much so that the operating system initially used a full screen web browser window as its interface, and contained limited offline functionality. Later versions of ChromeOS introduced

2600-684: Was doing the same, at least in the United States. An August 2012 article by John C. Dvorak in PC Magazine claimed that the term "netbook" is "nearly gone from the lexicon already", having been superseded in the market place largely by the more powerful (and MacBook Air inspired) Ultrabook —described as "a netbook on steroids"—and to a lesser extent by tablets. In September 2012 Asus, Acer and MSI announced that they will stop manufacturing 10-inch netbooks. Simultaneously Asus announced they would stop developing all Eee PC products, instead focusing on their mixed tablet-netbook Transformer line. With

2652-557: Was to be released in May 2011. The Z670 processor, part of the Oak Trail platform, delivers improved video playback, faster Internet browsing and longer battery life, "without sacrificing performance" according to Intel.
