IDF: Ultrabooks with at least nine hours of battery life
One of the stated goals of the 2013 next-generation Core i, Intel currently being developed under the code name Haswell is a significantly reduced energy consumption: how it should CPU models provide a further lowered TDP (Thermal Design Power). For long term use, however, the idle power is crucial, where Intel introduced a year ago, a reduction by a factor of 20 in view.
In practice, this has Intel's hobbyhorse, the Ultrabooks, big impact. In advance of starting on Tuesday in San Francisco IDF (Intel Developer Forum) us for an imaginary notebook manufacturers with the presentation requirements for Haswell Ultrabooks leaked: These notebooks have to last at least nine hours without power. This creates even been some recent Ultrabook, but are currently required "only" five hours. Manufacturers must meet Intel's requirements catalog to promote a device as Ultrabook allowed, which again is connected with grants from Intel's marketing budget.
The term is not the only point that will change. For further mandatory program includes an HD-capable webcam, and an array of at least two microphones, which improves the filtering of unwanted signals. The microphone array is to serve not only in combination with the webcam for video conferencing more understandable, but also for voice control of the notebook. Specifically Intel Dragon Assistant Nuance calls as voice control software, but will also allow competitors.
Wireless was previously already mandatory, now Intel specifies the requirements: wireless adapter with only one data stream to transmit and receive direction - ie with IEEE 802.11n respectively 150 MBit / s - will no longer be permitted. Instead, at least two streams per direction are required (300 Mbit / s). Even faster wireless IEEE 802.11ac is also allowed with at least two data streams per direction, but not mandatory. First matching wireless routers are available recently. In addition, Wireless Display (WiDi) is inevitable, and the manufacturer have to necessarily build one of Intel's Centrino modules.
In connection with the WLAN module takes Intel Smart Connect on by default: This technique resembles coarse the Connected standby of Windows 8 and wakes up the notebook itself constantly at intervals from standby to search applications can check for new messages, and puts it afterwards back to sleep. The advantage is obvious: After switching users can get started with the current data set and do not need to manually refresh the email inbox or Facebook wall.
For further mandatory program a pre-installed anti-virus program will include - Intel bought McAfee is well known, however, brings Windows 8 anyway with a virus protection. Even large touchpad are required to identify at least two-finger gestures. At convertible devices with touch screens also added more sensors such as accelerometer, gyroscope, compass and ambient light sensors. Such Ultrabooks may still be two millimeters thicker than non-touch devices, the housing rules remain the same: Above 14-inch screen size are allowed a maximum of 21 millimeters thick, with a maximum of 18 mm (excluding feet).
At the perceived speed is still true that an Ultrabook has to wake up to at least seven seconds from sleep mode. It goes easily with SSDs, classic hard drives but is a small additional buffer required SSD (Intel Rapid Start). Such Ultrabooks it even today already, but often up to 32 GB SSD cache can be installed, which is used exclusively for rapid awakening - in the operation of the cache is simply broke. The latter is at Haswell Ultrabooks allowed no more: For systems with hard disk must have at least 16 GB of SSD cache be verhanden that are not explicitly used to wake up, but intercept the holding disk accesses, so the notebook responds faster to inputs (SSD Caching) .
In addition to the mandatory requirements are Intel and notebook manufacturers have a long list of optional features to the hand. To request program are strongly colored screens with at least 1920 × 1080 pixels and wide viewing angles, NFC interfaces (eg for Internet payments using NFC-compatible credit card), Mobile Phones (UMTS / LTE) and the high-speed Thunderbolt port.
To the eve of the IDF aging conversation 10-watt processors is presenting award no details, but mentioned altered TDP stages: The Ultrabook-grade ULV models will in future be content with 15 instead of 17 watts. This does not exclude that there will be perhaps even additional, more energy-efficient models. Possible hardware equipment in some places such as CPU variants are called with LPDDR3 memory.
"Normal" notebook processors will be at Haswell with 37 and 47 watts, which is about two watts TDP values of current Core i models. Such processors include Intel, however, explicitly from the Ultrabook specification, although you can also build it extremely thin laptops, such as Apple has proven with the MacBook Pro with retina display. In future there will be those powerful Flasks in the Windows world, for example at the IFA presented U500 Zenbook from Asus.
