GPUs do not run a general purpose OS. CPUs do (at least if you run
Linux, Windows, BSD, OSX, Solaris etc). HUGE difference. This plays a
major role. The overall architecture of a GPU is very, very different
from a CPU, making the code that runs on them more deterministic. GPUs
also do not service interrupts from every device on your system.

not all PCs can do it. but its simply not true that "PCs can't do it".
