Why not just desing a single really powerful processor?

Designing a single powerful processor can lead to challenges in heat dissipation, power consumption, and manufacturing complexity. As performance scales, diminishing returns may occur due to physical limitations, making it less efficient. Furthermore, parallel processing through multiple simpler cores often provides better performance for diverse workloads, improving overall efficiency and responsiveness. Thus, a heterogeneous approach with multiple specialized processors can be more effective and adaptable to various tasks.
