联想 ThinkPad X13 Gen 4 AMD 笔记本电脑评测：性能平平的紧凑型 Ryzen 机器
联想 ThinkPad X13 Gen 4 是采用 AMD Ryzen CPU 的最小巧的 ThinkPad 之一。遗憾的是，小巧的体积导致了一些妥协，这在 CPU 性能方面表现得非常明显。
AMD Ryzen 7 PRO 7840U, Radeon 780M, 13.3", 1.3 kgAMD Ryzen 7 PRO 7840U
AMD Ryzen 7 PRO 7840U 是凤凰系列中速度最快的高端笔记本电脑处理器，也是 U 系列中速度最快的机型。它基于支持超线程（16 线程）的Zen 4 架构，提供 8 个内核（八核心）。内核频率从 3.3（基本）到 5.1 GHz（单核提升）。处理器包括 8 MB 二级缓存和 16 MB 三级缓存。
与消费级 Ryzen 7 7840U相比，PRO 型号提供了额外的安全性、可管理性和可靠性功能，专为专业用户和工作站环境而设计。
根据工作负载的不同，R7 PRO 7840U 的性能仅略低于 Ryzen 7 7840HS(更高的基本时钟速度和 TDP）。与上一代产品相比 Ryzen 7 PRO 6850U相比，由于采用了 Zen 4 架构和更高的时钟速度，7840U 的速度明显更快。
该芯片集成了名为 Radeon 780MRadeon 780M，拥有 12 个 CU，时钟频率高达 2.7 GHz。此外，Phoenix 系列还包括一个具有 AV1 de- 和编码功能的视频引擎、一个基于 Xilinx FPGA 的全新XDNA AI 加速器（Ryzen AI），其速度应该比Apple M2 SOC 中的 AI 引擎更快；以及一个双通道 DDR5-5600 / LPDDR5x-7500 内存控制器（支持 ECC）。连接功能包括 2 个可能的 USB 4（40 Gbps）端口和 20 个 PCIe 4.0 通道，用于 GPU 和 SSD。
Phoenix 系列采用单芯片设计（不同于 7045HX 系列的芯片组设计），在台积电采用现代4 纳米工艺制造。TDP 可在 15 至 30 瓦之间配置。
