Intel Core Ultra 7 251HX

Intel Ultra 7 251HX

英特尔酷睿至尊 7 251HX是基于箭湖架构的游戏笔记本移动高端 CPU。它提供 18 个内核,包括 8 个快速性能内核中的 6 个,主频高达 5.1 GHz,以及 16 个效率较低的内核中的 12 个,主频高达 4.5 GHz。CPU 可以访问 30 MB 二级缓存和 30 MB 三级缓存,TDP 为 45 瓦。

SoC 集成了一个名为 AI Boost 的小型专用 NPU,具有 13 个 TOPS (Int8),不支持 vPro。集成内存控制器最高支持 256 GB DDR5-6400(双通道,可选 ECC)。集成图形处理器(iGPU)是一个小型英特尔图形显卡,有四个 Xe 内核,运行频率为 300 - 1800 MHz。

性能 - 高端

由于有 18 个内核和高时钟频率,性能应介于 酷睿至尊 7 245HX超 7 255HX之间。因此,其性能足以满足 2016 年所有高要求应用和游戏的需要。

生产--台积电和 Foveros

Arrow Lake-HX 芯片基于桌面级 Arrow Lake-S 芯片,由多个芯片组组成。CPU 部分由台积电采用现代 N3B(3 纳米)工艺制造。GPU 也采用台积电的 N5P 工艺制造。SoC 和 I/O 芯片采用台积电 N6 工艺制造。底层芯片由英特尔公司采用 22 纳米工艺制造,并通过 Fovero 的 3D 封装实现了单个芯片的封装。
