AMD Radeon 780M vs Intel UHD Graphics 770

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.

Intel UHD Graphics 770

The UHD Graphics 770 is an integrated graphics card (IGP, GT1) in Alder Lake and Raptor Lake SoCs that offers 32 execution units (EUs) and a clock speed of up to 1.65 GHz (depending on the CPU model).

The performance depends on the CPU model it is integrated in and the used memory. The gaming performance is even on fast models only suited for low demanding games in 720p and low detail settings. Higher demanding games like Cyberpunk 2077 or Dying Light 2 (see benchmarks below) did not run well in our tests.

The GPU supports up to 4 displays with eDP 1.4b (5k120), DisplayPort 1.4a (8k60) and HDMI 2.1 (4k60). 

The Alder Lake SoCs are manufactured in the "Intel 7" named process (enhanced 10nm at Intel).
