I know what purpose they serve, but aren’t they both just doing calculations?
In: Technology
The CPU has a relatively small number of cores – up to 4 in home computers, and up to 32 in high end workstation CPUs. Each of these cores if very fast and can do lots of different kinds of calculations.
Meanwhile, a GPU has a large number of relatively weak cores, which specialize in calculations that are used mainly for displaying graphics. A single GPU core is much slower than a CPU core, but there are literally hundreds or even thousands of cores in the GPU, all calculating at the same time.
