If we're comparing incompatible platforms, then the Apple M4 Max's iGPU is weaker than the Playstation 5 Pro's AMD iGPU in everything except for memory capacity.

Intel has a competitive iGPU in the low-power mobile space. Their iGPUs in general are also pretty solid for general desktop use. But even in the x86 space, AMD has better-performing iGPU options than anything Intel has ever offered.
