AMD Radeon RX 7900M 是一款移动高端显卡，基于 5 纳米制造的 Navi 31 芯片（RDNA 3架构）。它拥有 4608 个内核（72 个 CU - 计算单元）和 16 GB 快速 GDDR6 显存，通过 256 位内存总线连接。芯片还包括 64 MB Infinity 高速缓存。AMD 表示，内核的时钟速度取决于笔记本电脑。指定的游戏时钟速度为 1825 MHz（很可能是在 180 W TGP 的情况下）。
AMD 将其性能与移动 RTX 4080 进行了比较，结果显示，在一些游戏中，7900M 平均快 7%。硬件支持光线追踪，但通常比 Nvidia 的同类产品慢。Nvidia 的优势还包括在特定游戏中支持 DLSS。
Navi 31 芯片由台积电采用当前的 5 纳米工艺制造。功耗（TGP）规定为 160 至 180 瓦（200 瓦，包括 CPU 的 SmartShift）。
