Central Processing Units (CPUs), graphics card cores, memory dies, and SSD flash memory dies predominantly adopt a square design. This shape choice is rooted in several pragmatic considerations. Firstly, a square maximizes the efficient utilization of silicon wafers, minimizing material waste incurred during the cutting process. Secondly, the square design facilitates orthogonal circuit wiring, which optimizes signal transmission and simplifies the intricate design of the clock distribution network, thereby ensuring precise timing consistency. Furthermore, square packaging simplifies the placement of pins and motherboard wiring, making it a universally adopted practice within the industry.
