CPUs (processors, or central processing units) on desktops and laptops (and even portable devices such as smart phones) have progressed from mainly one‐core processors to multicore processors with 2, 4, 8, or more cores. With multicore processors, multiple tasks can be done in parallel.

GPUs (graphics processing units), previously reserved for doing calculations to display graphics, can do some types of calculations, such as certain matrix manipulations, extremely quickly as they have many, many cores.
