Intel Processor U300

Intel U300

英特尔处理器 U300 是面向 Raptor Lake-U 系列轻薄笔记本电脑的入门级移动 CPU。它于 2023 年初发布,提供 1 个高性能内核(P-cores,很可能是类似 Alder Lake 的 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 6 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 相比 酷睿 i7-6700HQ).所有内核均可使用高达 8 MB 的 L3 高速缓存。

性能

性能应与旧版 Alder Lake 奔腾 8505唯一的区别是 U300 支持更高的 LPDDR5 频率。处理器 酷睿 i3-1305U也非常相似,但提供了更多的三级缓存,P 核心的提升时钟速度提高了 100 MHz。

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 1.1 GHz。

功耗

U300 的基本功耗为 15 W,英特尔建议的最大 Turbo 功耗为 55 W。CPU 采用英特尔改进的 10 纳米 SuperFin 工艺制造(仍称为英特尔 7)。
