Why are CPU chips always square?

 

The square shape of CPU chips is primarily due to manufacturing efficiency and simplicity. Square or rectangular shapes are easier to produce consistently and reliably during the manufacturing process.

Round or irregular shapes would require more intricate cutting and shaping processes, which could increase production costs and potentially introduce more complexities in the manufacturing process. Additionally, a square shape allows for a more straightforward arrangement of components and connections within the chip's architecture, aiding in the design and layout of the integrated circuits.

While the functionality of the CPU doesn't necessarily require it to be square, the square shape has become a standard due to the advantages it offers in manufacturing and design.
