配备英特尔酷睿 i5-12450H 处理器的 Geekom Mini IT12 评测 - 性能卓越、配备两个 USB 4 端口的迷你 PC
Intel Core i5-12450H | Intel UHD Graphics 64EUs (Alder Lake 12th Gen) | 572 g
英特尔酷睿 i5-12450H 是基于 Alder Lake 架构的笔记本电脑高端移动 CPU。它于 2022 年初发布,提供 6 个高性能内核中的 4 个(P-cores,Golden Cove 架构)和 8 个高效内核中的 4 个(E-cores,Gracemont 架构),总共 8 个内核(八核 CPU)。P 核心支持超线程技术,与 E 核心结合可支持 12 个线程。高性能集群的时钟频率为 2 至 4.4 GHz,高效集群的时钟频率为 1.5 至 3.3 GHz。E 核心的性能应与旧版的 Skylake 核心类似(比较 酷睿 i7-6700HQ).所有内核均可使用多达 12 MB 三级缓存。与 12500H12450H 的 E 核心数量更少、时钟频率更低、iGPU 速度更慢,而且不支持 vPro。
性能
在我们的 数据库中有点令人失望,其多线程基准测试成绩仅与 Ryzen 7 5700U和 酷睿 i7-10750H截至 2023 年第二季度,这两款芯片都相当老旧。
您的使用情况可能会有所不同,这取决于 CPU 功耗限制有多高,以及您系统的散热解决方案有多强。
功能特点
集成内存控制器支持各种内存类型,最高可达 DDR5-4800、DDR4-3200、LPDDR5-5200 和 LPDDR4x-4267。线程指令(硬件)可支持操作系统决定在性能核心或高效核心上使用哪个线程,以获得最佳性能。对于人工智能任务,CPU 还集成了 GNA 3.0 和 DL Boost(通过 AVX2)。第 8 版的 Quick Sync 与 Rocket Lake CPU 相同,支持 MPEG-2、AVC、VC-1 解码、JPEG、VP8 解码、VP9、HEVC 和 AV1 硬件解码。CPU 仅支持 PCIe 4.0(一个 GPU x8,两个 SSD x4)。
集成图形适配器基于 Xe 架构,提供 96 个 EU(执行单元)中的 48 个,工作频率高达 1.2 GHz。
CPU 的基本额定功率为 45 瓦(95 瓦 PL2),但大多数笔记本电脑的 PL1 功率约为 60 瓦。SoC 采用英特尔 10 纳米工艺制造,即英特尔 7。
