I still somehow wonder, how cheap low MHz Chips can
outperform my
GHz PC system. The answer seems to be parallelism of computations,
which the GPUs (or DSPs) support better than CPUs.
This also means, that faster CPUs won't necessarily bring
the effect we are waiting for.
(To play many software effects/instruments in an acceptable time.)
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.
Anyway. If the PCs can't do it, someone has to
create a new
system, or extend the PC anyway to make it capable.
not all PCs can do it. but its simply not true that "PCs can't do it".
