Engineering samples are the beta versions of integrated circuits that are meant to be used for compatibility qualification or as demonstrators.〔(Intel's Information about Intel Engineering / Qualification Sample Processors )〕 They are usually loaned to OEM manufacturers prior to the chips commercial release to allow product development or display. Usually, they are picked out of a very large batch and perform correctly. However, rarely they may have faults that were fixed in the production model. Engineering samples are usually handed out under a non-disclosure agreement or an other type of confidentiality agreement. Some engineering samples, such as Pentium 4 processors were rare and favoured for having unlocked multipliers. More recently, Core 2 engineering samples have become more common and popular. Asian sellers were selling the Core 2 processors at major profit. Some engineering samples have been put through strenuous tests. Engineering sample processors are also offered on a technical loan to some full-time employees at Intel, and are usually desktop extreme edition processors. ==References== 〔 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「Engineering sample」の詳細全文を読む スポンサード リンク
