Intel Core Ultra 7 255H

Intel Ultra 7 255H

英特尔酷睿至尊 7 255H是基于箭湖架构的移动高端 CPU，适用于大型笔记本电脑。它提供 16 个内核，包括 6 个主频高达 5.1 GHz 的快速性能内核（Lion Cove）和 8 个主频高达 4.4 GHz 的小型高效内核（Skymont），以及另外两个主频高达 2.5 GHz 的 "低功耗 "高效内核（Skymont）。CPU 可访问 24 MB 高速缓存，TDP 为 28 瓦（PL1，115 瓦 PL2）。

SoC 集成了一个名为 AI Boost 的小型专用 NPU，具有 13 个 TOPS (Int8)，可选择支持 vPro Essentials。集成内存控制器支持高达 192 GB LPDDR5/x-8400 或 DDR5-6400（双通道）。集成图形处理器（iGPU）是一块 英特尔 Arc 140T 图形卡它提供八个 Xe 内核，主频高达 2.25 GHz。

性能 - 高端

酷睿至尊 7 优于顶级型号 酷睿至尊 9 285H仅在最大 Turbo 频率上降低了 200 MHz。由于内核（尤其是高效内核）的 IPC 有所改进，CPU 的性能应略低于旧版的 猛禽湖酷睿 9 270H(6 + 8 核心，最高 5.8 / 4.1 GHz）的水平。这使得该 CPU 非常适合高端游戏和内容创建等要求苛刻的任务。

芯片组设计

与台式机芯片和 HX 芯片一样，Arrow Lake-H 芯片也是基于单个芯片，这些芯片采用 Foveros 3D 封装，置于英特尔提供的 22 纳米基片上。CPU 部分来自台积电，采用现代 N3B（3 纳米）工艺。与 HX 一样，GPU 也在台积电生产，采用 N5P 工艺制造。SoC 和 I/O Tile 也来自台积电，但采用的是较早的 N6 工艺。
