AMD Ryzen AI 5 PRO 340

AMD Ryzen AI 5 PRO 340是 Krakan Point 系列中一款功能强大的移动处理器，于 2025 年初在 CES 上发布。该 APU 集成了 6 个 CPU 内核（3 个 Zen 5 内核，最高主频 4.8 GHz；3 个 Zen 5c 内核，缓存较少，最高主频 3.4 GHz）和 16 MB 三级缓存。与几乎相同的消费级芯片相比 Ryzen AI 5 340相比，PRO 版支持更多的管理和安全功能。

架构和功能

Krackan Point 系列 APU 采用 Zen 5 和 Zen 5c 微架构内核，分别位于不同的集群中。Zen 5 和 Zen 5c 的区别之一是缓存的大小；Zen 5 内核的缓存更大。

不过，据报道(ChipsAndCheese由于缓存大小不同、AVX-512 吞吐量差异较大等因素，移动 Zen 5 的实现更接近桌面 Zen 4，而不是桌面 Zen 5。

在其他方面，Ryzen AI 5 芯片支持 DDR5-5600 和 LPDDR5x-8000 内存，让系统设计人员可以在更低的延迟和更高的吞吐量之间做出选择。该芯片原生兼容 USB 4（因此也兼容 Thunderbolt）。它支持 PCIe 4.0，与 8000 系列的前代产品一样，每通道吞吐量为 1.9 GB/s。集成的 XDNA 2 NPU 比第一代 XDNA 复杂得多，可提供多达 50 个 INT8 TOPS，用于加速各种人工智能工作负载。

与笔记本 CPU 一样，Ryzen 5 AI 芯片是焊接的，用户无法更换。

性能

得益于 Zen 5 架构和高时钟频率，CPU 性能应该会非常出色。

图形性能

显卡 Radeon 840M是缩小版的 Radeon 890M仅提供 4 个内核（CU = 256 着色器），主频高达 2.9 GHz。它采用全新的 RDNA 3.5 架构。

功耗

据说 AI PRO 340 的基本 TDP 为 28 W，不过笔记本电脑制造商可以在 15 至 54 W 之间自由设定 TDP。

这些 CPU 采用 4 纳米 TSMC 工艺制造，确保了高于平均水平的能效。
