AMD Ryzen 7 255

Ryzen 7X4X/8X4X CPU

Ryzen 7 255 是 Hawk Point 系列中的一款芯片。该芯片与较早的 Ryzen 7 8745H相同，有 8 个内核（由于支持 SMT，因此有 16 个线程），运行频率高达 4.95 GHz（与 8745H 相比提高了 50 MHz），并配备了仍然相当强大的 Radeon 780MiGPU。未安装/激活用于人工智能加速的 NPU。

性能表现

我们预计这款 Zen 4 架构处理器的速度将与 Ryzen 7 7745HX(8 个 Zen 4 内核，主频 3.6 GHz 至 5.1 GHz），这意味着其多线程性能略好于 Core Ultra 9 185H但比 Ryzen AI 9 HX 370.

架构和功能

与 Zen 3 不同的是，Zen 4 支持 AVX512，并进行了其他改进，如全面采用更大的缓存/寄存器/缓冲器。除此之外，8745H 还有 16MB 三级缓存和快速内存控制器（最高 LPDDR5x-7500 和最高 DDR5-5600）。有 20 个 PCI-Express 4 通道，用于连接 NVMe SSD（每通道 1.97 GB/s）和显卡等设备；还支持 USB 4 / Thunderbolt。请注意，APU 不可超频，用户不能更换。它永久焊接在主板上（FP7r2 或 FP8 插座接口）。

图形

显卡 Radeon 780M(12 个 CU / 768 个着色器，频率高达 2,600 MHz）可同时驱动 4 台显示器，分辨率高达 SUHD 4320p。最常见视频编解码器（AV1、AVC、HEVC）的硬件编码和硬件解码也不成问题。就游戏而言，在 2025 年初，许多游戏仍能以 1080p 的分辨率运行，即使大多数设置为低分辨率或低分辨率。

功耗

Ryzen 7 系列芯片的长期功耗限制（标准 TDP）为 35W 至 54W，这让系统制造商可以选择提高电池续航时间或让他们开发的系统更快。无论如何，配备该 APU 的笔记本或迷你 PC 都必须使用主动散热解决方案。
