全新华为 MateBook 14 评测:替代 MacBook Air 的尝试
Intel Core i5-1240P | Intel Iris Xe Graphics G7 80EUs | 14.00" | 1.4 kg
英特尔酷睿i5-1240P是一款中端Alder Lake-P系列SoC,旨在用于超轻、超薄的笔记本电脑。它在2022年初宣布,它有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)相匹配。i5的P核具有超线程功能,与E核结合后,总共有16个线程。时钟速度在性能集群上从1.7 GHz到4.4 GHz,在高效集群上从1.2 GHz到3.3 GHz。与酷睿i5-1250P相比,该处理器的缺点包括:iGPU时钟速度略低,vPro功能集有限(只有 "精华 "层,不允许远程管理)。
架构
E-core应该和Skylake核心一样快(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i5-1240P的所有CPU核心都可以访问12MB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;英特尔建议使用不超过64GB的内存。与其他Alder Lake处理器一样,这款酷睿i5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(FCBGA1744插座接口)。
性能
我们预计12个CPU核心的性能将超过大多数即将推出的28W四核Tiger Lake部件(如Core i5-1145G7),同时也将击败许多6核和8核笔记本级AMD Ryzen 4000和Ryzen 5000选项,其运行时钟速度与1240P所能提供的类似。性能的可持续性可能与系统的功率限制有多高和冷却解决方案有多好有关,因此基于1240P的笔记本电脑可能会落后于大多数第12代H系列英特尔CPU。不过,由于金海湾核心带来的明显的架构改进,这款CPU的每线程性能显然会舒适地超过许多第11代虎湖CPU。
图形
内置的图形适配器为80 EU Iris Xe,运行频率高达1.3 GHz,与某些虎湖-UP3处理器(如i5-1135G7)相比变化不大,因为该iGPU具有现代功能,如AV1视频解码能力和SUHD 4320p显示器支持。Xe对休闲游戏并不陌生;也就是说,你的里程数可能会有所不同,这取决于电源限制有多高,以及笔记本电脑的冷却解决方案有多强。期待接近NVIDIA的MX350,或者换句话说,在大多数游戏中以1080p/低设置进行游戏时,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
i5的基本功率(也称为默认TDP值或PL1)为28W;其涡轮功率(也称为PL2)为64W。
