Geekom Mini IT12评论:搭载英特尔酷睿i7-1260P的英特尔NUC竞争者工作起来非常安静
Intel Core i7-1260P | Intel Iris Xe Graphics G7 96EUs | 572 g
英特尔酷睿i7-1260P是一款中上等的28W Alder Lake CPU,设计用于超轻笔记本电脑。它在2022年初宣布,它具有4个性能核心,而不是顶级的i7-1280P的6个核心(P-cores,Golden Cove架构)与8个高效核心(E-cores,Gracemont架构)配对。P-cores支持超线程,与E-cores结合时总共有16个线程。高性能集群的时钟速度为2.1 GHz至4.7 GHz,高效集群的时钟速度为1.5 GHz至3.4 GHz。与酷睿i7-1270P相比,i7-1260P的缺点包括:时钟速度略低,对vPro功能的支持有限(仅 "精华 "级别,不允许远程管理)。
架构
E-cores的性能应该类似于Skylake核心(在Core i7-6700HQ和其他选项中发现),在这一点上有六年的历史。酷睿i7-1260P的所有CPU核心都可以访问18MB的L3缓存。集成内存控制器支持各种内存类型,包括LPDDR5-5200、DDR5-4800、LPDDR4x-4267或DDR4-3200;作为参考,英特尔建议使用不超过64GB。正如其他Alder Lake处理器一样,英特尔酷睿i7-1260P配备了线程主管(Thread Director),这是一项新功能,旨在帮助Windows 11决定哪些核心用于哪些工作负载,以尽可能实现最佳性能和效率。通过GNA 3.0和DL Boost(通过AVX2)支持AI算法的硬件加速。对PCI-Express 5.0的支持还没有进入笔记本级的Alder Lake处理器,所以用户将不得不暂时满足于PCI-Express 4.0。
请注意,这不是一个用户可更换的CPU。它被永久地焊接在主板上(BGA1744插座接口)。
性能
我们预计12个CPU核心的性能将轻松超过任何即将推出的28W四核Tiger Lake部件(如Core i7-1195G7),同时也将击败大多数6核和8核笔记本级的AMD Ryzen 4000和Ryzen 5000选项。性能的可持续性可能在很大程度上取决于给定系统的功率限制有多高和热能有多好,因此大多数基于1260P的笔记本电脑在单核或短期负载以外的情况下可能会落后于12代H系列英特尔CPU。尽管如此,由于金海湾核心在架构上的明显改进,每线程的性能保证会舒适地超过老虎湖系列处理器。
图形
内置的图形适配器是96欧盟Iris Xe,运行频率高达1.4GHz,与虎湖-UP3处理器(如i7-1165G7)相比没有变化,这几乎不是一个缺点,因为这个iGPU具有现代功能,如AV1视频解码能力和SUHD 4320p显示器支持。这款图形适配器最多可同时使用4台显示器。它的游戏性能势必与笔记本电脑的功率限制和冷却解决方案有多高有关;期望接近英伟达的MX350,或者换句话说,在大多数游戏中以1080p/中等设置进行游戏时,帧率可以接受。由于Iris Xe没有专用的视频内存,因此快速的内存是获得良好性能的先决条件。
电源消耗
i7的基本功率(也称为默认TDP值或PL1)为28W,64W为其涡轮功率(也称为PL2)。酷睿i7-1260P采用英特尔第三代10纳米工艺制造,被称为英特尔7,具有良好的能源效率。
