Not possible. CPUs are *central* processing units for a reason:
because they are generalised processors that can do anything. GPUs are
*graphics* processing units, modern ones being designed to do 3D
modelling in hardware. This means they can do certain types of
mathematical operation very fast, but it doesn't mean that they are
replacement CPUs or better than CPUs in general.

It's like keen darts players: they can subtract down from 501 to zero
very quickly, but it doesn't mean they're good at arithmetic: many can
only add 3 numbers of 1-20 and 2x and 3x those numbers, 25 and 50,
nothing else, and they can't multiply or divide worth a damn. They are
practiced at one task.

GPUs are not some miracle new device. They're not wonder-processors
that are better than "boring old x86" chips. It doesn't work like
that. The x86 is a far more versatile, elaborate and clever device,
with years of brilliant design going into it; GPUs are one-trick
ponies. Great for that one trick, completely useless for anything

Ignore the hype. Just because certain types of math can now be done on
GPUs does not mean GPUs are the future or are going to change
