Radeon 840M是一款相当强大的 RDNA 3.5 架构 iGPU，于 2025 年初在 Krakan Point APU 中首次亮相，是 Radeon 740M.它的引擎盖下仅有一些不同之处，如更快的缓存；其 4CUs/WGPs （256 个统一着色器）运行频率高达 2,900 MHz。
它支持 DX12 Ultimate、光线追踪、AI 图像生成和其他现代功能，还支持许多流行的视频编解码器，首先包括 AVC、HEVC、VP9 和 AV1。与英特尔 Lunar Lake 芯片不同的是，最新加入的 VVC 编解码器不支持硬件。支持 Miracast 和 FreeSync。iGPU 可同时驱动多达 4 台显示器，分辨率高达 SUHD 4320p60。
预计 AMD 将在 2027 年之前完全支持基于 RDNA 3.5 的 GPU。
其游戏性能足以在低图形设置下玩 2024 款游戏。从规格上看，840M 应该比一般的 Radeon 740M.
Krakan Point 芯片采用单芯片设计，这意味着 iGPU 与 CPU 内核采用相同的台积电 N4P 工艺制造，因此能效高于平均水平（截至 2024 年底）。
