Intel's New 915P/G Express and 925X Express Chipsets Add 7.1 Audio & HD Support
In one of the most significant PC platform changes in a decade, Intel Corporation today announced products that usher in a range of audio, video and other capabilities previously found only on specialty PCs. In addition to making the PC experience more entertaining and productive, these technologies pave the way for such emerging capabilities as High Definition (HD) video, 7.1 surround sound and robust file protection for office and home users.
These technologies are helping create a new kind of PC, an all-in-one "hi-fi" device with high-definition video, high-fidelity sound and wireless connectivity, according to Louis Burns , vice president and general manager, Intel Desktop Platforms Group.
"Intel innovation is taking the PC through a significant evolution that opens up a broader set of new consumer uses," Burns said. "This evolution will help people to better enjoy digital music, photos, videos and games on PCs and other devices in and around the home. At the same time, the technologies we are introducing for the PC platform will help drive new uses that boost office productivity, such as simultaneously using multiple monitors with just one PC to work on and track several projects."
A trio of new Intel® chipsets - the "glue" between the microprocessor and the rest of the PC - and several new Intel® Pentium® 4 processors supporting Hyper-Threading Technology (HT 1 ) are the foundation of these new platforms. PCs powered by Intel® 915 G/P and 925X Express Chipsets, formerly codenamed Grantsdale and Alderwood, became commercially available worldwide today. These new chipsets are coupled with the latest Pentium 4 processors supporting HT Technology 5xx sequence, which are built on Intel's most advanced 90nm manufacturing process technology and run at speeds up to 3.60 GHz.
Advanced Sights and Sounds
Audio quality on the PC is upgraded with Intel® High Definition Audio, which supports 7.1 surround sound. The proliferation of DVDs (more than 1 billion were sold worldwide in 2003 2 ) coupled with the rapidly growing availability of high-definition video content raise the importance of advanced audio. These events are leading up to making the PC an "all-in-one" entertainment device.
The new platforms support other compelling new audio capabilities, such as the ability to use a simple software setting to turn all the output jacks on a PC into headphone jacks so several colleagues can listen simultaneously from the same PC in a quiet environment. This ability gives the consumer much more flexibility in configuring how audio plays or is recorded on a system. The Intel High Definition Audio solution also allows the unique capability of sending multiple sound streams simultaneously through the PC's output jacks, allowing one user to listen to an MP3 with headphones while another user is watching a video with multichannel surround sound from the same PC.
With nearly 70 million digital cameras projected to be sold worldwide in 2004 3 , billions of digital photographs are finding their way to PCs. The rise of digital technology means PC users are embracing technologies that can protect their priceless photo, video and audio memories from accidental loss. On PCs equipped with multiple hard drives, optional Intel® Matrix Storage Technology can boost storage performance and help protect irreplaceable work files and personal digital memories through advanced technologies normally found in data centers (using RAID 0 and 1 capability).
Also introduced is Intel® Wireless Connect Technology 4 , which enables consumers to set up and configure a wireless home network in four steps. On systems configured with an optional version of an Intel 915 G/P or 925X Express Chipset plus a separate Intel® PRO/Wireless 2225BG Network Connection solution, this feature allows for easier sharing of digital videos, photos and music in and around the home or office. It also allows for multiple wireless-enabled PCs to share one Internet connection or printer. Intel® Wireless Connect Technology has been introduced with systems expected to be available in limited quantities later this year.
"These new technologies will help drive the digital revolution in the home and make the digital office more secure and productive," Burns said. "The Intel 915G Chipset is a key component of the desktop platform for the next iteration of the Intel® Stable Image Platform Program (Intel SIPP). Intel SIPP can help companies reduce IT costs by simplifying the testing, deployment and management of their PC infrastructure."
The goal of Intel SIPP is to reduce the number of platform configurations, resulting in fewer software images in a business IT environment. Wipro NerveWire* conducted a PC management study and found that an increase in overall IT support costs directly correlates with the number of desktop PC hardware configurations. For example, doubling the number of PC configurations in a businesses IT environment from 20 to 40 increased the annual support cost by 96 percent 5 .
Improved Graphics Capability
Integrated into the Intel 915G Express Chipset, the Intel® Graphics Media Accelerator 900 (Intel GMA 900) will provide new graphics features particularly suited to digital home and office applications. For example, one function allows workers to use dual-independent displays - utilizing multiple screens with just one PC - to make use of old monitors and be more productive. Video editors and people analyzing multiple sets of data are just a few of the users who will benefit from this capability. Additionally, support for wide screen LCD televisions has been added to the Intel 915G Express Chipset, including support for cutting edge HD-TV formats such as 1080i. Today's 3-D entertainment on the PC is demanding increased performance; special new features being used in many of today's cutting-edge games are supported by Intel GMA 900.
Upgraded Internal Infrastructure
In a major boost to the computer's video, graphics and overall data throughput performance, the Intel 915 GP and 925X Express Chipsets will be Intel's first PC chipsets to feature a new higher-speed memory called DDR2, which provides headroom for the continued growth of PC platform uses. They will also feature PCI Express* bus architecture, a new, higher bandwidth bus technology with up to 3.7X the throughput capability 6 of the decade-old PCI standard. This increased bandwidth coupled with the multitasking benefits of HT Technology optimizes playback and simultaneous recording of HD video content, allowing a user with an HDTV tuner and appropriate software to watch a movie while recording a television program at the same time on just one PC, all in crisp HD quality.
