AMD Radeon 840M

The Radeon 840M is a fairly powerful RDNA 3.5 architecture iGPU that debuted in early 2025 in Krakan Point APUs and a direct successor to the Radeon 740M. It packs just a few differences under the hood, such as faster caches; its 4CUs/WGPs (256 unified shaders) run at up to 2,900 MHz.
DX12 Ultimate, ray tracing, AI image generation and other modern features are all supported here, as are many popular video codecs including first and foremost AVC, HEVC, VP9 and AV1. The latest addition to that list, the VVC codec, is not HW-supported unlike it is with Intel Lunar Lake chips. Miracast and FreeSync support is present. The iGPU can drive up to 4 monitors simultaneously with resolutions as high as SUHD 4320p60.
RDNA 3.5-based GPUs are projected to be fully supported by AMD until some time in 2027.
Performance
Its gaming performance is good enough for playing 2024 games in low graphics settings. Looking at the specs, the 840M should be slightly faster than the average Radeon 740M.
Power consumption
Krakan Point chips are a single-die design, meaning the iGPU is built with the same TSMC N4P process as the CPU cores for above average, as of late 2024, power efficiency.
