AMD Ryzen 9 7845HX

AMD R9 7845HX

AMD Ryzen 9 7845HX是龙腾系列中速度最快的高端笔记本电脑处理器。它基于支持超线程（24 线程）的Zen 4架构，提供 16 个内核中的 12 个。内核频率从 3（基本）到 5.2 GHz（单核提升）不等。7845HX 是目前推出的速度第二快的移动 Ryzen CPU，源自台式机的 Ryzen 9 7900X.

Dragon Range 系列仍然使用芯片组设计，采用 5nm 工艺制造的两个 CCD 簇（每个簇有 8 个可能的核心）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。

性能

我们数据库中 7845HX 的平均性能与 酷睿 i9-13900HX就多线程基准测试成绩而言，7845HX 与酷睿 i9-13900HX 处于同一水平。截至 2023 年中期，这是一款速度超快的芯片；当然，您的笔记本电脑的散热解决方案有多好，CPU 功耗限制有多高，可能会影响您的使用体验。

R9 7845HX 的额定 TDP 为 55 瓦，配置范围为 45 至 75 瓦（cTDP）。
