'''Coffee Lake'''是[[英特尔|英特爾]]給[[Skylake微架構|Skylake]]和[[Kaby Lake]]後的新一代14[[纳米|奈米]]製程的[[中央处理器|處理器]]系列——第八代[[酷睿|酷睿系列]]处理器所分配的代號。这些处理器的內置[[圖形處理器|顯示核心]]都支援[[DisplayPort|DP]] 1.2、[[HDMI]] 2.0和[[HDCP]] 2.2，且原生支援在2666MHz频率下的[[雙通道記憶體技術|雙連結]]DDR4[[随机存取存储器|記憶體]]。

功耗方面，[[筆記型電腦]]低壓处理器（代號Coffee Lake-U）處理器的[[热设计功耗|TDP]]為15W-28W；筆記型電腦標準電壓處理器（代號Coffee Lake-H）的TDP為35W-45W，物理核心最多為6個。<ref name="wccftech-Coffeelake">{{Cite web|url=http://wccftech.com/intel-14nm-coffee-lake-10nm-cannonlake-2018/|title=Intel Planning To Bring 14nm Coffee Lake 6 Core Chips in 2018 on Mainstream PCs – To Coexist With 10nm Cannonlake Processors|date=July 2016|last=Mujtaba|first=Hassan|work=WCCFTech|accessdate=2017-10-06|archive-date=2017-10-07|archive-url=https://web.archive.org/web/20171007200725/http://wccftech.com/intel-14nm-coffee-lake-10nm-cannonlake-2018/|dead-url=no}}</ref>。

桌面端方面，Coffee Lake處理器与上一代酷睿处理器相比，主要的变化為i5和i7升级为六颗核心（但只有i7具有[[超執行緒|超线程技术]]），i3则第一次有了4个物理核心（之前的i3仅有两个物理核心）。

Coffee Lake的处理器使用300系列的[[芯片组]]，与旧的 100 和 200 系列芯片组不兼容，而 300 系芯片组的主板亦无法安装六代或七代的酷睿 CPU。而下一代仍會使用14nm工藝，直到14nm工艺已没有更多提升空间為止。<ref>{{Cite web|url=http://www.kitguru.net/components/motherboard/paul-taylor/intel-300-series-chipsets-to-provide-usb-3-1-gen2-and-gigabit-wi-fi/|title=Intel 300-series chipsets to provide USB 3.1 Gen2 and Gigabit Wi-Fi {{!}} KitGuru|accessdate=April 29, 2017|language=en-US|archive-date=2017-05-06|archive-url=https://web.archive.org/web/20170506072213/http://www.kitguru.net/components/motherboard/paul-taylor/intel-300-series-chipsets-to-provide-usb-3-1-gen2-and-gigabit-wi-fi/|dead-url=no}}</ref>

Coffee Lake基于 Intel 的第二代 14nm 制程工艺（14++）。<ref>{{Cite news|url=https://www.anandtech.com/show/11859/the-anandtech-coffee-lake-review-8700k-and-8400-initial-numbers/2|title=The AnandTech Coffee Lake Review: Initial Numbers on the Core i7-8700K and Core i5-8400|last=Cutress|first=Ian|accessdate=2017-10-05|archive-date=2017-10-05|archive-url=https://web.archive.org/web/20171005202621/https://www.anandtech.com/show/11859/the-anandtech-coffee-lake-review-8700k-and-8400-initial-numbers/2|dead-url=no}}</ref> 更好的制程能让晶体管的大小更小。与旧款CPU相比，同样的面积能放入更多的晶体管，且能用更低的电压运行在更高的频率上（即更节能）。

Coffee Lake标志着个人电脑中处理器核心数的一次大升级，而上一次这样的升级还是十年前的 [[Core 2 Duo]]。這次的升級主要是因为[[超威半导体|AMD]]的[[AMD Ryzen|Ryzen]]系列處理器。

该系列的处理器已于2017年10月5日正式推出市场。

== 与Kaby Lake相比的变化 ==
Coffee Lake 系列与旧式的 Skylake 或 Kaby Lake 处理器相比，其变化如下所列：

* 大部分处理器增加2个核心；
* 提升三级缓存的大小；
* i5和i7的[[Intel睿频加速|睿频]]最高可额外提升200[[MHz]]；
* 集成显卡频率提升50MHz；
* i5和i7原生支持2666Mhz的DDR4内存，i3原生支持2400MHz DDR4内存，停止对DDR3内存的支持；
* 与第一代[[LGA 1151]]不兼容；
* 採用300系芯片组。

== Kaby Lake Refresh和Coffee Lake ==

2017年的8月8日，英特尔宣布第八代酷睿处理器将于 8 月21日发布。<ref>{{Cite news|url=https://techreport.com/news/32367/intel-eighth-generation-core-cpus-will-shine-bright-on-august-21|title=Intel's eighth-generation Core CPUs will shine bright on August 21|last=Manion|first=Wayne|date=August 8, 2017|publisher=Tech Report|accessdate=August 21, 2017|archive-date=2017-10-19|archive-url=https://web.archive.org/web/20171019055602/http://techreport.com/news/32367/intel-eighth-generation-core-cpus-will-shine-bright-on-august-21|dead-url=no}}</ref> 鉴于Intel的新产品一般会替换前代产品的微架构，因此一般认为新的 CPU 將會採用Coffee Lake微架构（雖没有任何證據證明這一點）。<ref>{{Cite news|url=http://www.anandtech.com/show/11738/intel-launches-8th-generation-cpus-starting-with-kaby-lake-refresh-for-15w-mobile|title=Intel Launches 8th Generation Core CPUs|last=Cutress|first=Ian|date=August 21, 2017|publisher=Anandtech|accessdate=August 21, 2017|archive-date=2017-10-22|archive-url=https://web.archive.org/web/20171022010707/https://www.anandtech.com/show/11738/intel-launches-8th-generation-cpus-starting-with-kaby-lake-refresh-for-15w-mobile|dead-url=no}}</ref>然而，當第八代酷睿处理器在 2017 年的8月21日正式发布的时候，英特爾指出，八代酷睿包括多種架構，包括Kaby Lake Refresh（主要用于超极本）、Coffee Lake。<ref>{{Cite news|url=https://www.pcper.com/reviews/Graphics-Cards/Intel-announces-8th-Generation-Core-Processors-starting-15-watt-quad-core-Kab|title=Intel announces 8th Generation Core Processors, starting with 15-watt quad-core Kaby Lake refresh for notebooks|last=Shrout|first=Ryan|date=August 21, 2017|publisher=PC Per|accessdate=August 21, 2017|archive-url=https://web.archive.org/web/20180806115415/https://www.pcper.com/reviews/Graphics-Cards/Intel-announces-8th-Generation-Core-Processors-starting-15-watt-quad-core-Kab|archive-date=2018-08-06|dead-url=yes}}</ref>
