AMD Radeon 780M vs AMD Radeon 860M

AMD Radeon 780M

The AMD Radeon 780M is an integrated GPU in the Ryzen 7040 series for laptops (Phoenix, e.g. Ryzen 9 7940HS). The iGPU is based on the new RDNA3 architecture and has 12 CUs (= 768 shaders) clocked at up to 3 GHz (depending on the CPU model). As the predecessor Radeon 680M, the 780M supports hardware raytracing, although the performance is too slow to use it in current games.

Thanks to the new architecture and higher clock speeds, the Radeon 780M should be clearly faster then the old Radeon 680M. This means most demanding games should be playable in minimum graphics settings (like Cyberpunk 2077) and less demanding games like Fifa 23 can be played in higher settings and resolutions (1080p). In early 2023, the Radeon 780M is the fastest iGPU on the market.

Thanks to the modern 4nm process and clever power-saving features, the power consumption is comparatively low (according to AMD). The whole chip of the first two models can be configured between 15 - 54 Watt TDP.

AMD Radeon 860M

The Radeon 860M 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 760M. It packs just a few differences under the hood, such as faster caches; its 8 CUs/WGPs (512 unified shaders) run at up to 3,000 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.

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.
