华硕 ExpertBook B3 评测:运行时间长达 11 小时的强大办公笔记本电脑
Intel Core i7-1355U | NVIDIA GeForce RTX 2050 Mobile | 14.00" | 1.7 kg
英特尔酷睿 i7-1355U是一款面向轻薄笔记本电脑的高端移动 CPU,基于 Alder Lake 架构(Raptor Lake-U / RPL-U 系列)。它于 2023 年初发布,提供 2 个高性能核心(P 核心,Golden Cove 架构)和 8 个高效核心(E 核心,Gracemont 架构)。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 1.7 至 5 GHz,高效集群的时钟频率为 1.2 至 3.7 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。CPU 支持"Essentials" vPro管理功能。与 P 系列(28 瓦)或 H 系列(45 瓦)相比,15 瓦的 TDP 可能会限制持续性能。
性能
得益于较高的时钟频率,酷睿 i7-1355U 的性能应略高于较早的酷睿 i7-1265U(最高 4.8 GHz)略胜一筹。更快的 i7(如 i7-1365U 型号)只能提供更高的时钟频率(和更快的 iGPU)。
架构
集成内存控制器支持各种内存类型,最高可达 LPDDR5-6400。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。针对人工智能任务,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 仍然只支持 PCIe 4.0 x8(用于 GPU)和两个 PCIe 4.0 x4(用于 SSD)。
集成显卡基于 Xe 架构,提供全部 96 个 EU(执行单元),工作频率高达 1.3 GHz。
功耗
这款酷睿 i7 CPU 的额定 TDP 为 15W(基本功率,PL1),最大涡轮功率为 55W(PL2)。RPL-U 处理器采用进一步改进的英特尔 7 处理器(10 纳米 SuperFin),允许更高的时钟频率。
