HP 250 G9 评测--配备酷睿 i3 处理器和 IPS 面板的经济型办公笔记本电脑
Intel Core i3-1215U | Intel UHD Graphics 64EUs (Alder Lake 12th Gen) | 15.60" | 1.7 kg
英特尔酷睿 i3-1215U 是一款面向轻薄笔记本电脑的中端移动 CPU,基于 Alder Lake 架构。它于 2022 年初发布,提供 2 个高性能内核(P-cores,Golden Cove 架构)和 4 个高效内核(E-cores,Gracemont 架构)。P 核心支持超线程技术,与 E 核心结合可支持 8 个线程。高性能集群的时钟频率范围为 1.2 至 4.4 GHz,高效集群的时钟频率范围为 0.9 至 3.3 GHz。E 核心的性能应与旧的 Skylake 核心类似(与酷睿 i7-6700HQ 比较 酷睿 i7-6700HQ).所有内核均可使用高达 10 MB 的 L3 高速缓存。与速度更快的 i5 和 i7 型号相比,i3 不包括 vPro 功能。
性能
我们数据库中 1215U 的平均性能与 Ryzen 3 5300U以及 酷睿 i7-1185G7的多线程基准测试成绩。截至 2022 年底,这一成绩已经足够体面。对于一款入门级 CPU 而言,这已经很不错了。
您的选择可能会有所不同,这取决于您笔记本电脑的散热解决方案有多好,以及 CPU 的功率限制有多高。
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)。
集成显卡基于 Xe 架构,提供 96 个 EU(执行单元)中的 64 个,工作频率高达 1.1 GHz。
CPU 的额定基本功率(TDP,PL1)为 15 瓦,最大功率(PL2)为 55 瓦。整个 SoC 采用英特尔 10 纳米工艺制造,即英特尔 7。
