AMD Ryzen 5 7645HX

AMD R5 7645HX

AMD Ryzen 5 7645HX 是龙腾系列中速度最快的高端笔记本处理器。它基于 Zen 4 架构，提供 6 个内核，支持超线程（12 个线程）。内核频率从 4（基本）到 5 GHz（单核提升）不等。

R5 7645HX 的性能应明显高于 Ryzen 6000 移动系列中最快的 6 核 CPU，即 Ryzen 5 6600H.得益于全新的 Zen 4 内核和相对较高的时钟频率，单线程性能尤其出色。这意味着即使是老式的 Ryzen 9 6980HX(同样是 5 GHz，但采用 Zen 3 处理器）在单线程工作负载中的速度也会稍慢。

Dragon Range 系列仍然使用芯片组设计，采用 5nm 工艺的两个 CCD 簇（每个簇有 8 个可能的核心，7645HX 只使用一个 CCD，8 个核心中有 6 个核心）和一个 IO-die（包括内存控制器和 Radeon 610M iGPU）采用 6 纳米制程。芯片集成了 4 个 USB 3.2 Gen2（10 Gbps）端口（无 USB4）、28 个 PCIe 5.0 通道（用于 GPU 和 SSD）和一个双通道 DDR5-5200 内存控制器。

R5 7645HX 的额定 TDP 为 55 瓦，最高可配置为 75 瓦（cTDP）。
