Asus Zenbook UX21 Ultrabook

Ultrabook is a specification and brand developed by Intel for a class of high-end subnotebooks which are designed to feature reduced bulk without compromising performance and battery life. They use low-power Intel Core processors, solid-state drives, and unibody chassis to help meet these criteria.[1] Due to their limited size, they typically omit common laptop features such as optical disc drives and Ethernet ports.[2]

History[edit]

In 2012, Intel Capital press officer Jordan Balk Schaer announced a new fund to support startups working on technologies in line with the company's concept for next generation notebooks.[3] The company set aside a $300 million fund to be spent over the next three to four years in areas related to Ultrabooks.[3] Intel announced the Ultrabook concept at Computex in 2011. The Ultrabook would be a thin (less than 0.8 inches thick[4]) notebook that utilized Intel processors, and would emphasize portability and a longer battery life than other laptops[3][4] By this marketing initiative and an associated $300 million fund, Intel hoped to influence the slumping PC market against rising competition from smartphones[5] and tablet computers,[6] which are typically powered by competing ARM-based processors.[7]

The Ultrabook directly competes against other subnotebooks, including Apple’s MacBook Air, which has similar form specifications and is powered by Intel CPUs, but runs Mac OS X (with Boot Camp it can run Microsoft Windows as well).[8][9][10]

At the Intel Developer Forum in 2011, four Taiwan ODMs showed prototype Ultrabooks that used Intel's Ivy Bridge chips.[11] Intel plans to reduce power consumption of its chips for Ultrabooks, like Ivy Bridge processors, which will feature 17W default thermal design power.[12]

At a presentation at the Consumer Electronics Show, an Intel manager stated that market analysis revealed that screen size motivated some of the reluctance to switch to 13" Ultrabooks. As a result, Intel planned to ensure, through cooperation with manufacturers, a 14 or 15-inch screen on 50% of the 75 Ultrabook models that would likely come to market in 2012.[13][14]

IHS iSuppli had originally forecast that 22 million Ultrabooks would be shipped by the end of 2012, and 61 million would be shipped in 2013. By October 2012, IHS had revised its projections down significantly, to 10 million units sold in 2012 and 44 million for 2013.[15] The cheapest Ultrabooks started at $900 USD, instead of the more mainstream $600 USD (as of 2012), and most Ultrabooks retailed at well over $1000 USD which made them too expensive to be widely adopted.[16][17] In addition Intel's constant changing of Ultrabook specifications caused confusion among consumers; and this was compounded by OEMs that released slim/"sleek" or "Sleekbook" laptops (e.g. Hewlett-Packard Pavilion TouchSmart 15z-b000 Sleekbook, Samsung Ativ Book 9 Lite) that are cheaper AMD-powered variants of their more expensive Intel-equipped Ultrabooks.[18][19] Overall there was the shift in the market away from PCs as a whole (including Ultrabooks) and towards smartphones and tablet computers (particularly the iPad) as the personal computing devices of choice.[5][20][5]

While Apple's MacBook lines have not been immune to this consumer trend towards mobile devices,[21] they still managed to ship 2.8 million MacBooks in Q2 2012 (the majority of which are the MacBook Air) compared to 500,000 total Ultrabooks,[22][23] despite there being dozens of Ultrabooks from various manufacturers on the market while Apple only offered 11-inch and 13-inch models of the Macbook Air.[24] While several Ultrabooks were able to claim individual distinctions such as being the lightest or thinnest, the Air was regarded by reviewers as the best all-around Ultrabook in regard to "OS X experience, full keyboard, superior trackpad, Thunderbolt connector and the higher-quality, all-aluminum unibody construction".[25] The Air was among the first to receive Intel's latest CPUs before other PC manufacturers, and Apple Mac OS X has gained market share on Windows in recent years.[26][27] Through July 1, 2013, the MacBook Air took in 56 percent of all Ultrabook sales in the United States, despite being one of the higher-priced competitors. [28] It should be noted that Apple has traditionally dominates the premium PC market, in 2009 having a 91 percent market share for PCs priced at more than $1,000, according to NPD, and Ultrabooks were an attempt by other PC manufacturers to move in on Apple's turf.[29]

Intel banked on the release of Windows 8 as well as new form factors, such as "convertible" laptops with touchscreens and tablets with keyboard docks,[30] and features (accelerometers and gyroscopes for touchscreens, hand-gesture recognition) to build demand for Ultrabooks.[20] With the third generation Ultrabook specification, introduced in June 2013 alongside its new Haswell processor architecture, Intel also added the requirement for all future Ultrabooks to include touchscreens; the requirement is intended to prevent "game-playing" and market confusion from OEM's, who had offered low-end products with touchscreens but not Ultrabooks.[31]

Specifications[edit]

Intel requires manufacturers to meet certain specifications in order to market a laptop as an Ultrabook.[32] These requirements change with each release of Intel's mobile platform.
