Why are GPUs so big, while CPUs are so small?
In: Engineering
CPUs are built to do a lot of small tasks quickly, GPUs are built to chew through a single large task quickly.
CPU is a sprinter: fast to accelerate, quick to finish.
GPU is like a long distance runner or a power lifter.
Your premise is incorrect. Big GPUs require big cooling, which makes them big. Big cpus (14900k for example) also required big cooling, which also makes them big. Small GPUs (integrated graphics, rtx 3050) dont require bit cooling, and can be pretty small.
GPUs use parallel processing while CPUs use serial. GPUs have many more cores than CPUs which allows them to process several small tasks at a time; while, CPUs are better at processing one large task at a time. These differences contribute to the die size of both the GPU and CPU making modern GPUs larger in size.
