Nvidia Ion is a product line of Nvidia corporation intended for motherboards of low-cost portable computers. It uses graphics processing units and chipsets intended for small products. ==Description== Nvidia Ion products include a GeForce 9M (9xxxM) series MCP79MX (with integrated GeForce 9400M G GPU) chipset, DDR3-1066 or DDR2-800 SDRAM, and the Intel Atom processor. The original reference platform was based on a Pico-ITXe motherboard designed for netbook and nettop devices. In February 2009, Microsoft certified the Ion-based platform for Windows Vista. The small form factor Ion-based computers were released in mid-2009. Ion systems were DirectX 10.0 and OpenGL 3.3 capable. This allowed playback of full 1080p high-definition video with true-fidelity 7.1 surround sound audio output with VDPAU or the Third Generation PureVideo HD feature.〔Computerbase.de: (Test: Zotac IONITX-A (Nvidia Ion), page 2 ): "Im Videobereich verlässt sich Nvidia beim Ion auf PureVideo HD der dritten Generation ()"〕 Ion systems can also use CUDA (Nvidia's General-Purpose Computing on Graphics Processing Units technology),〔(【引用サイトリンク】work= Nvidia web site )〕 as well as OpenCL. ION-LE–based systems shared the same basic hardware as ION but lacked Vista and DirectX 10 support.〔 It was originally believed to be unlikely that Ion systems would ever enter into mass production and were thus unlikely to pose competition to Intel's own chipsets for the Atom platform, due to Intel's unwillingness to supply Atom processors separate from the 945GSE and 945GC chipsets with which the CPUs are usually supplied.〔http://www.digitimes.com/news/a20081223PD216.html〕 While manufacturers could still buy an Atom-plus-chipset package and remove the CPU for use on an Ion board, it hardly seems likely given the costs involved, especially given the low-cost leanings of the nettop and netbook market.〔http://www.bit-tech.net/news/2008/12/26/intel-says-no-to-nvidia-s-ion/1〕 However, Intel later denied those claims, and a spokesperson for Intel said Intel sells Atom as a stand-alone processor.〔http://www.internetnews.com/bus-news/article.php/3793391/Intel%20Denies%20Squeezing%20nVidia%20Out%20From%20Atom.htm〕 Nvidia announced that it would release the Ion platform for the VIA Nano processor some time in Q4 2009.〔http://www.engadget.com/2009/02/20/nivida-ion-platform-to-support-via-nano-processors-this-year/〕 For full-sized laptops, the Ion platform promised 5x faster graphics and video transcoding with an 80% lower CPU cost when compared to the Intel GM45 graphics. For netbooks and nettops 10x faster graphics and video transcoding when compared to the Intel 945GSE graphics. For all-in-ones, the Ion platform is capable of displaying resolutions up to 2560 × 1600.〔 Acer announced the release of their Aspire Revo which is the first model available for retail purchase to be built on the Ion platform. Zotac International launched four Nvidia Ion-based motherboards in Mini-ITX form factor. An Ion system based on their IONITX A-U dual-core Atom 330 motherboard draws 30 watts total from the AC line cord, including hard disk and DVD drives, while playing and upscaling a DVD.〔http://www.flickr.com/photos/11292615@N02/3714919608/in/set-72157621353465380/〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Nvidia Ion」の詳細全文を読む スポンサード リンク
