In contrast, a GPU is composed of hundreds of cores that can handle thousands of threads simultaneously.” To sum it up, a quote I came across from Kevin Krewell from Nvidia explains it well: “Architecturally, the CPU is composed of just a few cores with lots of cache memory that can handle a few software threads at a time. The GPU is designed for parallel processing so they can work with a lot of data at once. The CPU is based on single cores so it works on one bit of data at a time.
A graphics processing unit, or GPU, is there to render 3D graphics and to help the CPU perform its calculations. Think of the central processing unit, or CPU, as the brain and control center of your computer.
