→GPU parallelization vs CPU
== GPU parallelization vs CPU ==
The GPU (Graphics Processing Unit) often consists of thousands of cores, whereas a typical modern multiple core CPU has somewhere between 2 - 128 cores. Even though the GPU cores are smaller than the CPU cores and are much slower at processing serial codes, the high number of cores makes GPUs perform better with parallelized codes in many cases.
