Celeron is a brand name given by Intel Corp. to a number of different IA-32 and x86-64 computer microprocessor models targeted at budget personal computers. Celeron processors can run all IA-32 computer programs, but their performance is often significantly lower when compared to similar CPUs with higher-priced Intel CPU brands. For example, the Celeron brand will often have less cache memory, or have advanced features purposely disabled. These missing features can have a variable impact on performance, but is often very substantial. While a few of the Celeron designs have achieved surprising performance, most of the Celeron line has exhibited noticeably degraded performance. This has been the primary justification for the higher cost of other Intel CPU brands versus the Celeron range. Introduced in April 1998, the first Celeron branded CPU was based on the Pentium II branded core. Subsequent Celeron branded CPUs were based on the Pentium III, Pentium 4, Pentium M, and Intel Core branded processors. The latest Celeron design () is based on the fourth generation Core i3/i5/i7 series (Haswell).〔(【引用サイトリンク】title=Products (Formerly Haswell) )〕 This design features independent processing cores (CPUs), but with only 66% as much cache memory as the comparable Core i3 offering. == Background == As a product concept, the Celeron was introduced in response to Intel's loss of the low-end market, in particular to the Cyrix 6x86, the AMD K6, and the IDT Winchip. Intel's existing low-end product, the Pentium MMX, was no longer performance competitive at 233 MHz. Although a faster Pentium MMX would have been a lower-risk strategy, the industry standard Socket 7 platform hosted a market of competitor CPUs which could be drop-in replacements for the Pentium MMX. Instead, Intel pursued a budget part that was pin-compatible with their high-end Pentium II product, using the Pentium II's Slot 1 interface. Intel hired marketing firm Lexicon Branding, which had originally come up with the name "Pentium", to devise a name for the new product as well. The ''San Jose Mercury News'' described Lexicon's reasoning behind the name they chose: "Celer is Latin for swift. As in 'accelerate.' And 'on.' As in 'turned on.' Celeron is seven letters and three syllables, like Pentium. The 'Cel' of Celeron rhymes with 'tel' of Intel." 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「Celeron」の詳細全文を読む スポンサード リンク
