'''K6-2'''是一個由AMD製造的[[x86]]處理器，也是AMD整个奔腾时期最成功的一个处理器序列。K6-2可以在200至550 MHz的時鐘速度運行。它有64Kb一級緩存（32KB指令集和32KB資料），在2.2[[伏特]]的電壓下運行。使用[[0.25微米製程]]，擁有930萬個[[電晶體]]，以及只能使用於處理器插座是[[Socket 7]]或[[Super Socket 7]]的主機版。<br />

== K6-2的歷史 ==<br />
<br />
[[File:Amdk62 arch.png|300px|thumb|AMD K6-2的內部結構。]]<br />
<br />
K6-2设计目的是作为当时比较老、更重要的是比较贵的[[Intel]] [[Pentium II]]的竞争对手。这两种CPU的性能很相似：K6-2的前代[[AMD K6|K6]]趋向于日常计算应用，而Intel的在浮点任务中无疑更强大。K6-2是一款非常成功的CPU，并为[[AMD]]提供了市场基础和财政稳定性，为日后发布[[Athlon]]做好准备。<br />
<!-- The K6-2 was designed as a competitor to the slightly older and significantly more expensive [[Intel]] [[Pentium II]]。Performance of the two chips was broadly similar: the previous [[AMD_K6|K6]] tending to be faster for general-purpose computing, the Intel part clearly superior at floating-point tasks. The K6-2 was a very successful chip and provided AMD with the marketing base and the financial stability it would need to introduce the [[Athlon]]。--><br />
K6-2是第一款引入浮点单指令多数据结构（[[SIMD]]）指令集——[[3DNow!]]的处理器，这套指令集大大推动了执行3维立体处理能力的进步。3D Now!成功打败了Intel在数月后推出的、相似但更复杂的[[SSE]]。<br />
<!-- The K6-2 was the first CPU to introduce a floating point [[SIMD]] instruction set (dubbed [[3DNow!]] by AMD), which could significantly boost the performance of 3D-enabled applications. It beat to the market the similar but more complicated [[Streaming SIMD Extensions|SSE]] instruction set from Intel, by several months. --><br />
几乎所有的K6-2都是在100MHz [[前端总线]]（FSB）的[[Super 7]]平台上开发的，这套平台为CPU性能提高提供了基础。在K6-2初期，K6-2 300MHz版本是卖得最好的。这个版本的热卖，为K6-2在市场上造就了一个极好的名声，并与[[Intel]] [[Celeron]] 300A在市场上剧烈地竞争。[[Celeron]]提供了一个小但快的缓存和卓越的浮点运算单元；K6-2提供更快的RAM访问（得益于Super 7主板）和3D Now!的3D绘图能力的扩充。两者不仅热卖，并且吸引的很多双方的支持者使用对方的系统。（在那时候，最快的[[Pentium II]]尽管比最快K6-2和Celeron快一点，但价格却高出不少）<br />
<!-- Nearly all K6-2s were designed to utilise 100 MHz Super 7 mainboards, and this provided a major boost to system performance. Early in the K6-2's career, the K6-2 300 was by far the best-selling variant. It rapidly established an excellent reputation in the marketplace and competed fiercely with Intel's [[Celeron]] 300A for the non-exotic performance market. The Celeron offered a smaller but faster cache and an excellent floating-point unit; the K6-2 offered much faster RAM access (courtesy of the Super 7 mainboard) and 3DNow graphics extensions. Both parts sold well, and both attracted their share of loyalists. (At this time, the fastest available Pentium IIs were slightly more powerful than either of the cheaper chips, but vastly more expensive.) --><br />
由于市场继续向前进，AMD发布了一系列更快的K6-2，而最畅销的型号从最初的300MHz，一直到了500MHz。到了450和500MHz的K6-2成为市场主流的时候，更新、更快的CPU已经占领了高端市场，但K6-2和它的竞争对手Celeron依然在各自公司的CPU种类预算中。K6-2的100MHz FSB的主板允许K6-2还算温柔地抵挡着不断增长的CPU倍频值，并且在剩余的生命依然令人惊奇地在市场上竞争着。<br />
<!-- As the market moved on, AMD released a long series of faster K6-2 parts, the best-selling ones being the 350, 400, 450, and 500. By the time the 450 and the 500 were mainstream parts, newer and faster chips had taken the high-performance market and K6-2s still competed with Celerons, but in the budget CPU category. The 100 MHz mainboard of the K6-2 allowed it to withstand the effects of ever-increasing CPU multipliers fairly gracefully and in later life it remained surprisingly competitive. --><br />
== K6-2+ ==<br />
鲜为人知的K6-2+是整合了128KiB二级缓存并采用[[0.18微米製程|0.18微米工艺]]的处理器（从本质上来说，这是[[AMD K6-III|K6-III]]的简化版）。K6-2+是明确为低功耗移动型（但它的發熱量很大）CPU，而且推出的时候正是主流台式机快速转型到诸如Athlon之类的新平台。这款CPU在其目标市场销量一般，但尽管AMD没有努力为其作宣传，K6-2+依然出现在传统台式机市场中销售。台式机版本的K6-2+在市场中完全将Athlon和K6-III的锋芒遮盖着（两者都比K6-2+快多了），甚至连较慢、只便宜一点点的原版K6-2也不例外，因为K6-2更知名和更容易找到匹配的主板。K6-2+最高频率为570MHz。<br />
<!-- The little-known K6-2+ was an enhanced K6-2 with 128&nbsp;KiB of integrated [[L2 cache]] and built on a 0.18 [[micrometre]] process. (Essentially, a smaller version of the [[K6-III|K6-III]]。) The K6-2+ was specifically designed as a low-power mobile CPU, and released at a time when mainstream desktop machines were fast moving on to newer platforms like the Athlon. It sold in modest numbers to its target market, and although AMD made no attempt to publicise this, it was also made available as an orthodox desktop CPU. The desktop-packaged K6-2+ was overshadowed in the market by the Athlon and the K6-III (both significantly faster parts) and the original K6-2 which, although slower and only marginally cheaper, was better-known and easier to source compatible motherboards for. The K6-2+ topped out at 570MHz. --><br />
