联想Legion 5 15IAX11评测：专为1440p游戏优化
2026款Legion 5 15的屏幕尺寸比上一代略大，但机身并未因此变得更重或更大。不过，在游戏时，这款OLED屏幕的强反光问题确实需要特别注意。
Intel Core Ultra 7 251HX, NVIDIA GeForce RTX 5070 Laptop, 15.3", 1.9 kgIntel Core 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和 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。
