Intel Core i7-1270P

Intel i7-1270P

英特尔酷睿 i7-1270P是更高端的 Alder Lake-P 系列 CPU,是一种昂贵的 28 W 部件,用于超轻、超薄(但主动散热)笔记本电脑。这款 CPU 于 2022 年初发布,拥有 4 个性能核心,而顶级的 1280P CPU 只有 6 个核心。 顶级的 1280P(P-cores,Golden Cove 架构)与 8 个高效内核(E-cores,Gracemont 架构)相匹配。P 核心支持超线程技术,与 E 核心结合可实现 16 个线程。高性能集群的时钟频率为 2.2 GHz 至 4.8 GHz,高效集群的时钟频率为 1.6 GHz 至 3.5 GHz。这款酷睿 i7 支持完整的 vPro 功能集("企业 "级,允许远程设备管理)。与强大的 i7-1280P 相比,它的不足之处包括 L3 缓存较小、核心数量较少、时钟速度较低;因此性能会明显降低。

简单浏览一下规格,就会发现这款 i7 系列芯片与 酷睿 i5-12600H非常相似,后者是一款针对游戏笔记本电脑的功耗更高的处理器。

架构

i7 是英特尔利用 ARM 开发的 big.LITTLE 技术为自身利益服务的延续。单个 "小 "Alder Lake 内核的速度应该与 Skylake 内核(如古老的 酷睿 i7-6700HQ等)的速度一样快,而 Skylake 内核在这一点上已经有六年的历史了。英特尔酷睿 i7-1270P 的所有 CPU 内核均可访问 18 MB 三级缓存。集成内存控制器支持各种内存类型,最高可达 LPDDR5-5200、DDR5-4800、LPDDR4x-4267 或 DDR4-3200。英特尔建议使用不超过 64 GB 的内存作为参考。与其他第 12 代英特尔酷睿处理器一样,酷睿 i7-1270P 也配备了线程指令(Thread Director),这是一项新功能,旨在帮助 Windows 11 决定将哪些内核用于哪些工作负载,以尽可能实现最佳性能和效率。通过 GNA 3.0 和 DL Boost(通过 AVX2)支持人工智能算法的硬件加速。Alder Lake P 处理器尚未支持 PCI-Express 5.0,因此用户暂时只能满足于 PCI-Express 4.0。四条 PCI-Express 4 通道允许高达 7.9 GB/s 的读/写速率,前提是有一个 NVMe 固态硬盘固态硬盘。

请注意,这不是用户可更换的 CPU。它被永久焊接在主板上(BGA1744 插座接口)。

性能

12 个 CPU 内核不仅能胜过任何即将推出的四核Tiger Lake 部件,i7-1195G7 也是如此。 i7-1195G7包括在内。在我们的数据库中,1270P 的平均性能直接与 Ryzen 7 5825URyzen 7 7730U7735U这意味着到 2023 年中期,这款小小的酷睿 i7 处理速度足以让大多数消费者满意。

相当高的处理能力是有代价的。在重负载情况下,单个 Golden Cove 核心的功耗可能超过 20 W。因此,您的使用情况可能会有所不同,这取决于功率限制有多高以及笔记本电脑的散热解决方案有多好。

显卡

内置图形适配器为 96 EU Iris Xe运行频率高达 1.40 GHz,与第 11 代Tiger Lake-UP3 处理器(如 i7-1165G7由于这款 iGPU 具备 AV1 视频解码能力和 SUHD 4320p 显示器支持等现代功能,这并不是什么缺点。这款 iGPU 最多可同时使用 4 台显示器。我们预计其游戏性能将相当接近于 英伟达™(NVIDIA®)的 MX350.

换句话说,在 1080p 分辨率/中等设置下,只要功率限制足够高,散热解决方案足够出色,Xe 就足以胜任大多数游戏。快速的内存也是获得良好性能的先决条件(Xe 没有专用显存)。

最后但并非最不重要的一点是,我们发现在播放 YouTube UHD 2160p60 视频时,图形处理器的利用率比使用Tiger Lake 芯片时更高。

功耗

i7 的基本功耗(也称为默认 TDP 或功率极限 1)为 28 W,最大 Turbo 功耗(也称为 PL2)为 64 W。至于 "最低保证 "功耗,英特尔的指南中提到为 20 W。总而言之,对于这样一款芯片,主动冷却解决方案是必不可少的。

该 CPU 采用英特尔第四代 10 纳米工艺制造,市场上称为英特尔 7,具有不错的能效(截至 2022 年底)。它仍然是一款相当耗电的 CPU;在重负载情况下,单个 P 核心的功耗将超过 20 W。几款更高端的 7 纳米 U 级 AMD Ryzen 5000 芯片在提供类似或更高性能水平的同时,功耗也没有那么高。
