<DIV id=ArticleCnt>
Intel处理器市场上，主流四核心还是2009年发布的45nm工艺Lynnfield，而高端六核心Gulftown、低端双核心Clarkdale都已经进化到32nm，甚至服务器领域的四核心Xeon都已升级为32nm。一切，将从明年的Sandy Bridge(以下简称SNB)开始改变。
45nm Nehalem架构首先出击高端市场，带来了LGA1366平台，32nm SNB架构则会先行登陆主流市场，平台再次更新为LGA1155，取代目前的LGA1156 Lynnfield/Clarkdale。
一、新名字
SNB家族仍然沿用Core i7/i5/i3的品牌＋子系列命名方式，编号上则采用四位数字，其中第一位均为“2”，代表第二代Core ix系列，最后末尾往往还有一个代表不同含义的字母：K代表不锁定倍频，都是高端产品；S代表性能优化，原始频率比没有字母后缀的低很多，但是单核心加速最高频率基本相同，另外热设计功耗都是65W；T代表功耗优化，热设计功耗只有45W或35W，但是频率也是最低的。
<A class=f14_link href="http://news.mydrivers.com/1/171/171882.htm" target=_blank>明年第一季度的首批SNB桌面处理器共有13款型号</A>，规格差异和现在一样错综复杂，想分清楚确实非常困难：
－ Core i7 3款；Core i5 7款、Core i3 3款；
－ K系列2款、S系列3款、T系列3款、无后缀5款；
－四核心八线程/三级缓存8MB 3款、四核心四线程/三级缓存6MB 6款、双核心四线程/三级缓存3MB 4款；
－ Turbo Boost动态加速支持10款、不支持3款；
－ 95W 5款、65W 5款、45W 1款、35W 2款。
另外它们还将全部整合图形核心，默认频率有850MHz、650MHz两种，动态加速频率则有1350MHz、1250MHz、1100MHz三种。

二、新架构
SNB处理器采用第二代32nm工艺、HKMG技术制造，直接整合GPU图形核心、内存控制器，并且图形核心也共享三级缓存，这和现在的Clarkdale/Arrandale双芯片封装方式截然不同。
虽然人们一向对Intel集成显卡嗤之以鼻，但SNB自带的GPU图形核心确实经过了大幅度的重新设计，拥有专门的视频转码硬件模块，性能大约是目前HD Graphics的两倍，测试也证明Intel所言非虚。
借助第二代Turbo Boost睿频加速技术，SNB的CPU、GPU两部分可以相互独立地动态加速。如果你正在玩的游戏更需要GPU资源，那么CPU部分可能会运行在原始频率甚至降低，GPU则在功率允许范围内尽量提速。反之亦然。
<IMG style="BORDER-BOTTOM: black 1px solid; BORDER-LEFT: black 1px solid; BORDER-TOP: black 1px solid; BORDER-RIGHT: black 1px solid" alt="迎接新时代：Sandy Bridge性能全面预览" src="http://news.mydrivers.com/Img/20100828/04214061.jpg" twffan="done">
CPU部分，流水线知之甚少，指令集和AMD推土机一样支持AVX。一级缓存仍是32KB指令、32KB数据、4个循环，二级缓存仍是低延迟的256KB、10个循环，只有三级缓存变化比较大：因为需要和GPU共享而更加重要，容量有8MB、6MB、3MB三种，延迟经测试减少为26个循环，大大低于Lynnfield的42个。
下个月的旧金山IDF 2010上，我们应该能获得更多技术细节。

三、新接口、新芯片组
这部分是很多人不欢迎的。Intel平台上我们现在已经有了LGA775、LGA1366、LGA1156三种封装接口，SNB还会带来两种，包括今天要看到的LGA1155(取代LGA1156)，以及明年下半年的高端LGA2011，取代LGA1366而支持四通道内存、八核心处理器
新接口自然需要新的芯片组来支持：首先是针对主流市场的P67、H67，再过一个季度还有入门级的H61。具体规格差异看下表：

P67不支持处理器集成显卡，但是可以组建双路x8模式的SLI/CrossFireX，而且内存倍频是开放的；H67不支持双独立显卡，内存也被限制在官方规格DDR3-1333。
P67、H67都有SATA 6Gbps原生接口，但数量仅为两个，另外四个还是SATA 3Gbps；USB 2.0接口多达14个，但没有USB 3.0；8条PCI-E信道升级为2.0标准，带宽翻番至5GT/s，每信道单向500MB/s、双向1GB/s，可很好地满足第三方USB 3.0控制器。
H61也是搭配处理器集显的，规格削弱很多，比如不支持RAID，USB 2.0接口减少到10个，SATA 3Gbps接口减少到4个而且没有SATA 6Gbps，PCI-E信道也减少为6条。
四、路线图、价格
Intel尚未公布SNB处理器的具体价格，但是对比路线图和当前价格表我们就可以看出个大概来。
<A href="http://news.mydrivers.com/Img/20100828/04243492.png" target=_blank><IMG style="BORDER-BOTTOM: black 1px solid; BORDER-LEFT: black 1px solid; BORDER-TOP: black 1px solid; BORDER-RIGHT: black 1px solid" alt="迎接新时代：Sandy Bridge性能全面预览" src="http://news.mydrivers.com/Img/20100828/S04243492.png" twffan="done"></A>
<A href="http://news.mydrivers.com/Img/20100828/04251245.jpg" target=_blank><IMG style="BORDER-BOTTOM: black 1px solid; BORDER-LEFT: black 1px solid; BORDER-TOP: black 1px solid; BORDER-RIGHT: black 1px solid" alt="迎接新时代：Sandy Bridge性能全面预览" src="http://news.mydrivers.com/Img/20100828/S04251245.jpg" twffan="done"></A>
比如说，Core i7-2600K的定位和Core i7-950差不多，而后者价格是562美元；Core i7-2600相当于Core i7-875K/i5-680，也就是284-342美元；最便宜的Core i3-2100和Core i3-550处于同一档次，亦即138美元。
另外从这份路线图上也可以清楚地看到，SNB将在明年第二季度降临奔腾品牌，第三季度再让赛扬焕发新生。
五、超频问题
超频是一个永恒的话题，但每次伴随着Intel平台的升级都会发生巨大的变化，SNB也不例外，或者说更糟糕。
SNB处理器会集成原本位于芯片组内的时钟发生器，这就将外频(BCLK)卡死在了100MHz左右，大幅提升的可能性为零。
如此一来超频将成为历史？基本上差不多，还能下手的地方就只有外频了。
首先，K系列会不会锁定倍频，可以自由调节，就像现在的Pentium E6700K、Core i7-875K、Core i5-655K(不过实践证明它们的超频能力实属一般)；
<IMG style="BORDER-BOTTOM: black 1px solid; BORDER-LEFT: black 1px solid; BORDER-TOP: black 1px solid; BORDER-RIGHT: black 1px solid" alt="迎接新时代：Sandy Bridge性能全面预览" src="http://news.mydrivers.com/Img/20100828/04225131.jpg" twffan="done"> Core i7-875K、Core i5-655K
其次，借助Turbo Boost动态超频，在所允许的最高倍频的基础上继续提升，多获得一些超频空间，当然这也不是无限制的，Intel也正在继续完善；
第三，倍频提升的同时，内存带宽也必须跟上，为此Intel稍稍放开了内存频率，P67主板上最高可以超到DDR3-2133。
总而言之，超频在SNB时代将变成一件很困难的事情，基本只能选择K系列聊以自慰。也许处理器极限超频将从此远离Intel。

六、测试平台
这次我们拿到的是一颗试产的Core i5-2400，四核心，主频3.1GHz，三级缓存6MB，本身不支持超线程，但为了更好地测试这种技术，Intel在目前的样品中打开了它，测试过程中我们也会分别考察两种情况。
由于还是样品的缘故，Turbo Boost动态加速技术无效，任何时候频率都固定在3.1GHz。
<A href="http://news.mydrivers.com/Img/20100828/04231475.jpg" target=_blank><IMG style="BORDER-BOTTOM: black 1px solid; BORDER-LEFT: black 1px solid; BORDER-TOP: black 1px solid; BORDER-RIGHT: black 1px solid" alt="迎接新时代：Sandy Bridge性能全面预览" src="http://news.mydrivers.com/Img/20100828/S04231475.jpg" twffan="done"></A>
GPU图形核心是单核心、6个执行单元。Intel还会在某些型号中使用双核心、12个执行单元，但还不知道具体会用在哪里。
从路线图上看，Core i5-2400和Core i5-650平级，后者目前价格是176美元。
测试中使用的主板是一款H67芯片组样品，内存是4GB DDR3-1333。其他配置还有：
主板： 华硕P7H57DV-EVO (Intel H57) Intel DP55KG (Intel P55) Intel DX58SO (Intel X58) Intel DX48BT2 (Intel X48) 技嘉GA-MA790FX-UD5P (AMD 790FX)
芯片组驱动： Intel INF 9.1.1.1015 AMD Catalyst 8.12
内存： 海盗船DDR3-1333 1GB×4 (7-7-7-20) 海盗船DDR3-1333 2GB×2 (7-7-7-20)
硬盘：Intel X25-M 80GB
显卡： EVGA GeForce GTX 280 (Vista) ATI Radeon HD 5870 (Win7)
显卡驱动： GeForce 180.43 (Vista) Catalyst 9.12 (Win7)
操作系统： Windows Vista Ultimate x86 (SYSMark) Windows Vista Ultimate x64 Windows 7 x64
七、集成显卡性能

尽管Intel集成显卡一向声名狼藉，尽管硬件和驱动还都不完善，但是SNB着实让我们吃了一惊：不仅相比现有的HD Graphics普遍翻了至少一番，还完全超越了AMD 890GX/790GX，甚至大多数时候都要比入门级独立显卡Radeon HD 5450更强一些。
而且不要忘了还有双核心、12个执行单元的高端版本，在此基础上再提高一倍的话……
HD Graphics在高清影音方面已经相当先进，SNB又会在游戏上大踏步前进，再加上AMD Fusion APU，入门级独立显卡真的没法混了。

八、图像编辑和视频编码性能 
<IMG style="BORDER-BOTTOM: black 1px solid; BORDER-LEFT: black 1px solid; BORDER-TOP: black 1px solid; BORDER-RIGHT: black 1px solid" alt="迎接新时代：Sandy Bridge性能全面预览" src="http://news.mydrivers.com/Img/20100828/04263247.png" twffan="done">
<IMG style="BORDER-BOTTOM: black 1px solid; BORDER-LEFT: black 1px solid; BORDER-TOP: black 1px solid; BORDER-RIGHT: black 1px solid" alt="迎接新时代：Sandy Bridge性能全面预览" src="http://news.mydrivers.com/Img/20100828/04263250.png" twffan="done">

Core i5-2400已经可以基本完胜频率相同、定位更高、价格更贵(583美元)的Core i7-880，开启超线程后还能在部分情况下获得进一步加速，Core i5-760也完全不是对手。

九、3D渲染性能 
<IMG style="BORDER-BOTTOM: black 1px solid; BORDER-LEFT: black 1px solid; BORDER-TOP: black 1px solid; BORDER-RIGHT: black 1px solid" alt="迎接新时代：Sandy Bridge性能全面预览" src="http://news.mydrivers.com/Img/20100828/04270961.png" twffan="done">

<IMG style="BORDER-BOTTOM: black 1px solid; BORDER-LEFT: black 1px solid; BORDER-TOP: black 1px solid; BORDER-RIGHT: black 1px solid" alt="迎接新时代：Sandy Bridge性能全面预览" src="http://news.mydrivers.com/Img/20100828/04274305.png" twffan="done">

再次表现不俗，普遍超过Core i7-880，超线程的效率也更明显。
十、文件压缩性能 
<IMG style="BORDER-BOTTOM: black 1px solid; BORDER-LEFT: black 1px solid; BORDER-TOP: black 1px solid; BORDER-RIGHT: black 1px solid" alt="迎接新时代：Sandy Bridge性能全面预览" src="http://news.mydrivers.com/Img/20100828/04274311.png" twffan="done">

多线程文件恢复测试中，Core i5-2400即使不开启超线程都能超过Core i7-880乃至六核心的Core i7-980X，而在压缩包创建测试中，Core i5-2400关闭超线程的时候和Core i7-880同级，打开之后则能逼近Core i7-980X。

十一、Windows 7游戏性能 
<IMG style="BORDER-BOTTOM: black 1px solid; BORDER-LEFT: black 1px solid; BORDER-TOP: black 1px solid; BORDER-RIGHT: black 1px solid" alt="迎接新时代：Sandy Bridge性能全面预览" src="http://news.mydrivers.com/Img/20100828/04274317.png" twffan="done">

这部分是搭配独立显卡进行的，唯一可以说的就是Core i5-2400确实相当快，游戏玩家的福音。
十二、功耗 
<IMG style="BORDER-BOTTOM: black 1px solid; BORDER-LEFT: black 1px solid; BORDER-TOP: black 1px solid; BORDER-RIGHT: black 1px solid" alt="迎接新时代：Sandy Bridge性能全面预览" src="http://news.mydrivers.com/Img/20100828/04281970.png" twffan="done">
<IMG style="BORDER-BOTTOM: black 1px solid; BORDER-LEFT: black 1px solid; BORDER-TOP: black 1px solid; BORDER-RIGHT: black 1px solid" alt="迎接新时代：Sandy Bridge性能全面预览" src="http://news.mydrivers.com/Img/20100828/04281973.png" twffan="done">
性能上去了，功耗却下来了。得益于第二代32nm HKMG工艺技术，Core i5-2400的待机系统功耗和Core i5-760/Core i7-880几乎完全相同，满载功耗更是最低的。
结语：
综合上述测试，Core i5-2400相比频率稍低的Core i5-760能带来平均23％的性能提升。对比更高端的Core i7-880，Core i5-2400在没有超线程的情况下也并不逊色多少，有些时候甚至还会更快。
换算下来，同等频率下SNB的性能提升幅度应该有10％左右，但是记住这里还没有开启Turbo Boost动态加速，最终零售版估计还能籍此再提升3-7％。
Nehalem架构的多线程效率很高，SNB架构看起来无论线程多少性能都表现很不错，证明了其复杂环境的执行效率。
当然了，SNB处理器还有一个好处，那就是负载功耗明显更低，而且参照路线图，同等性能级别的产品会更便宜一些。
SNB集成的图形核心也令人惊喜，性能远远甩开了现有整合芯片组，甚至堪比入门级独立显卡。也许长期压在Intel集成显卡头上的狼藉声名将从此一去不复返。
除了今天看到的种种，有关于SNB的话题其实还很多，比如改进的浮点性能和通用计算性能、尚未露面的Turbo Boost动态加速、集成的视频转码引擎……
