Alder Lake-S、Alder Lake-P和Alder Lake-M分别会有多少个内核
英特尔Alder Lake的最新揭秘：挑战传统界限
Intel的Alder Lake CPU家族不仅限于台式机领域，其卓越的技术正逐渐渗透到其他设备中。KitGuru的最新发现揭示了SiSoftware Sandra的更新，这个基准测试工具将支持三种创新的CPU架构变体：专为台式机打造的Alder Lake-S，以及面向笔记本的Alder Lake-P与低功耗Alder Lake-M。
这些CPU的核心架构融合了常规与节能模式，如同ARM的big.LITTLE技术，但每个SKU都根据设备性能进行定制。Alder Lake-M，例如，将配备2个高性能核心和最多8个低功耗核心，而Alder Lake-S则可能提供8个大核和同样数量的小核。
Coreboot的线索进一步揭示，Alder Lake-M将拥有10倍的PCH PCIe通道，相比之下，Alder Lake-P的规格将提升至12倍，预示着更高效的数据传输能力。
英特尔在CES 2021的演讲中，通过一份开源媒体驱动程序的提交，对Alder Lake-S的细节略显轻描淡写，暗示其将集成GT0.5或GT1 Xe-LP的iGPU，与Tiger Lake和Rocket Lake保持一致的架构。
尽管具体发布时间尚不明朗，但英特尔已确认Alder Lake系列将在2021年下半年全面出击。前CEO鲍勃·斯旺曾表示：“我们正全力以赴，Alder Lake台式机和笔记本将在下半年进入量产阶段。”
坊间传言，Alder Lake-S有望在9月与我们见面，比Rocket Lake的发布时间提前六个月，无疑将为市场带来新的期待。
diels-alder反应是什么
diels-alder反应是一种有机反应(具体而言是一种环加成反应)。共轭双烯与取代
烯烃
(一般称为亲双烯体)反应生成取代环己烯。即使新形成的环之中的一些原子不是
碳原子
，这个反应也可以继续进行。
机理：
狄尔斯-阿尔德反应是共轭双烯体系与烯或炔键发生环加成反应而得环己烯或1,4-环己二烯环系的反应。1928年德国化学家O.P.H.狄尔斯和K.阿尔德在研究丁二烯与顺丁烯二酐作用时发现这类反应:在这类反应中，与共轭双烯作用的烯和炔称为亲双烯体。
亲双烯体上的吸电子取代基(如羰基、氰基、硝基、羧基等)和共轭双烯上的给电子取代基都有使反应加速的作用。
这类反应具有很强的区位和立体选择性。当双烯和亲双烯体两者都有适当的取代基，使反应可能发生不同区位而得到两种产物时，事实上只有一种是主要的。
例如异戊二烯与丁烯酮反应，以得到甲基-(4-甲基-3-环己烯基)-甲酮为主: 在立体化学方面，这类反应都是顺式加成的，而且当反应物有可能生成内型和外型两种产物时，一般只得内型化合物。
