AMD Ryzen 9 8945HS
Ryzen 9 8945HS是一款重新命名的 Ryzen 9 7940HS两者之间几乎没有任何区别。具体来说，8945HS 是一款功能强大的 Hawk Point 系列笔记本电脑芯片，拥有 8 个 Zen 4 内核，主频为 4.0 GHz 至 5.2 GHz。这款 APU 于 2023 年下半年面世，其所有内核均支持 SMT，共有 16 个处理线程。
这款功能强大的 Ryzen 9 系列处理器配备了第二代 Ryzen AI 技术。处理器 Radeon 780M作为集成图形适配器。
架构和功能
Hawk Point 系列芯片采用 Zen 4 架构，就像 Phoenix 和 Dragon Range 系列芯片一样。这并不是说三者之间没有区别。与 7040 系列 APU 相比，Hawk Point 芯片的人工智能生成性能最多可提升 40%，使 DaVinci Resolve 和 Adobe Photoshop 等应用程序更加强大。
与 Zen 3 不同的是，Zen 4 支持 AVX512，并进行了大量其他改进，包括全面扩大缓存/寄存器/缓冲区，预计将比 Zen 3 实现两位数的 IPC 提升。
在其他方面，8945HS 拥有 16 MB 三级缓存，支持超快内存（最高 LPDDR5x-7500 或 DDR5-5600；不支持 ECC）。该处理器兼容 USB 4，因此也兼容 Thunderbolt；对 PCIe 的支持仅限于 4.0 规格，每通道吞吐量为 1.97 GB/s。提供 20 个通道。
操作系统支持仅限于 64 位版本的 Windows 11 和 Windows 10，当然也包括 Linux。需要注意的是，该芯片不可超频，用户也不可更换，因为它会被永久焊接（FP7、FP7r2、FP8 插座接口）。
性能
8945HS 是 R9 7940HS变相的 R9 7940HS，因此，期望该芯片的速度略高于 酷睿 i9-12900HK和 Ryzen 7 7840HS就多线程性能而言。
具体情况可能会有所不同，这取决于 CPU 的功耗限制有多高以及系统散热解决方案的能力有多强。
图形性能
显卡 Radeon 780M有 12 个 CU（768 个着色器），运行频率高达 2,800 MHz。截至 2023 年底，这是一款非常快速的 iGPU。它可让您使用多达 4 台分辨率高达 SUHD 4320p 的显示器，还能对最广泛使用的视频编解码器（包括 AVC、HEVC 和 AV1）进行硬件编码和硬件解码。更重要的是，它的速度足以满足 1080p 游戏的需要，只要中低细节设置即可。
具体情况可能会有所不同，这取决于 CPU 的功耗限制有多高、系统的散热解决方案有多强、系统内存的速度有多快（这里没有专用的 VRAM）。
功耗
Ryzen 9 系列芯片的长期功耗限制（默认 TDP）为 35 W 至 54 W，笔记本电脑制造商可以在更长的电池寿命和更高的性能之间做出选择。无论如何，使用该芯片的系统都必须采用主动散热解决方案。
8945HS 采用台积电的 4 纳米工艺制造，具有很高的能效（截至 2023 年底）。
