AMD Radeon 780M vs AMD Radeon 890M

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 890M

The Radeon 890M is the most powerful AMD iGPU, as of mid 2024. It features 16 RDNA 3.5 architecture CUs (1024 unified shaders) running at up to 2,900 MHz. Ray tracing, AI image generation and other modern features are all supported here, as are the most 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.

The AMD iGPU is capable of driving four SUHD 4320p60 monitors simultaneously. It also supports Miracast and FreeSync. RDNA 3.5-based iGPUs are projected to be fully supported by AMD until some time in 2027.

Performance

Performance-wise, the graphics adapter can be as slow as the Arc 8 or as fast as the RTX 2050 Laptop depending on the benchmark or game. On average, the 890M finds itself very close to the GTX 1650 Laptop making it possible to play 2024 AAA games at 1080p with most settings set to Low. Baldur's Gate 3 is playable on medium settings, as are several other 2023 games.

Power consumption

Strix Point chips are a single-die design, meaning the iGPU is built with the same TSMC N4P process as the CPU cores for very decent, as of mid 2024, power efficiency.

The 890M delivers as much performance as an entry-level desktop graphics card while consuming just 10 to 20 Watts.
