:I thought dual-core was SMP, was that wrong of me?
It is SMP, definitely. If one were to ask the question... how many
cpu's is enough? The answer is probably around four for any general
The biggest advantage a GPU has is its ability to process work in
parallel, either with parallel processing elements or with pipelined
elements. Because of this a GPU can do far more work then a CPU
within the bounds of its capabilities.
GPU makers have recently started trying to incorporate general purpose
computing elements into GPUs, but I think this effort is going to be
fairly short lived as consumer computers start to get more cores. My
guess is that GPUs will evolve better GPU<->CPU ABIs instead and most
of the supervisory workload will shift back to the CPUs. Pretty soon
game makers will be able to *rely* on consumer machines having 2 or more
cores in them. There won't be any more single-core consumer machines
two years from now.
