Core 2 is a brand encompassing a range of Intel's consumer 64-bit x86-64 single-, dual-, and quad-core microprocessors based on the Core microarchitecture. The single- and dual-core models are single-die, whereas the quad-core models comprise two dies, each containing two cores, packaged in a multi-chip module.〔(【引用サイトリンク】url=http://www.tgdaily.com/content/view/33708/135/ )〕 The introduction of Core 2 relegated the Pentium brand to the mid-range market, and reunified laptop and desktop CPU lines, which previously had been divided into the Pentium 4, Pentium D, and Pentium M brands. The ''Core 2'' brand was introduced on 27 July 2006, comprising the Solo (single-core), Duo (dual-core), Quad (quad-core), and in 2007, the Extreme (dual- or quad-core CPUs for enthusiasts) subbrands. Intel Core 2 processors with vPro technology (designed for businesses) include the dual-core and quad-core branches. == Models == The ''Core 2''-branded CPUs include: "Conroe"/"Allendale" (dual-core for desktops), "Merom" (dual-core for laptops), "Merom-L" (single-core for laptops), "Kentsfield" (quad-core for desktops), and the updated variants named "Wolfdale" (dual-core for desktops), "Penryn" (dual-core for laptops), and "Yorkfield" (quad-core for desktops). (Note: ''For the server and workstation "Woodcrest", "Tigerton", "Harpertown" and "Dunnington" CPUs see the Xeon brand''.) The Core 2 branded processors feature Virtualization Technology (with some exceptions), Execute Disable Bit, and SSE3. Their Core microarchitecture introduced SSSE3, Trusted Execution Technology, Enhanced SpeedStep, and Active Management Technology (iAMT2). With a maximum thermal design power (TDP) of 65W, the Core 2 Duo Conroe dissipates half the power of the less capable contemporary Pentium D-branded desktop chips〔(【引用サイトリンク】url=http://www.tomshardware.com/2006/01/05/the_65_nm_pentium_d_900s_coming_out_party/page6.html )〕 that have a max TDP of 130W.〔(【引用サイトリンク】url=http://www.tomshardware.com/2006/01/05/the_65_nm_pentium_d_900s_coming_out_party/page5.html )〕 With the release of the Core 2 processor, the abbreviation C2 has come into common use, with its variants C2D (the present Core 2 Duo), and C2Q, C2E to refer to the Core 2 Quad and Core 2 Extreme processors respectively. C2QX stands for the Extreme-Editions of the Quad (QX6700, QX6800, QX6850). The successors to the ''Core 2'' brand are a set of Nehalem microarchitecture based processors called Core i3, i5, and i7. ''Core i7'' was officially launched on 17 November 2008 as a family of three quad-core processor desktop models, further models started appearing throughout 2009. The last Core 2 processors to be released was the Core 2 Quad Q9500 in January 2010, and the Core 2 processor line was removed from the official price lists in July 2011.〔(【引用サイトリンク】url=http://www.intc.com/common/download/download.cfm?companyid=INTC&fileid=481200&filekey=85BC9BF7-1931-4032-8ADE-68D9A255973E&filename=July_10_11_1ku_Price.pdf )〕〔(【引用サイトリンク】url=http://files.shareholder.com/downloads/INTC/843929813x0x482714/D04F4947-6821-4B2B-A478-7A592F5CD716/July_17_11_1ku_Price.pdf )〕 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「Intel Core 2」の詳細全文を読む スポンサード リンク
