簡單說就是該CPU的版本
基本上從A0開始起跳
越後面技術越成熟
上面那位仁兄說成製程,有點不符合一般習慣的說法;rr;
一般我們說的製程是指process,也就是所謂90nm, 65nm, 45nm等等
列出一段英文維基百科的stepping原文給你參考:
Stepping
Stepping is a designation used by Intel and AMD to identify how much the design of a microprocessor has advanced from the original design. The stepping is identified by a combination of a letter and a number.
Typically, the first version of a microprocessor comes out with stepping A0. As design improvements occur, later versions are identified by changes in the letter and number. Changes in the number (for example, A3) indicate minor design changes, whilst changes to both the letter and number are made following more extensive changes (for example, B2). Stepping allows consumers and servicers to identify a microprocessor's version.
