20Core CPU !! I want to buy one of these for my Desktop :) BTW IMO AMD is too late to the party with 9W Ontario chip. The netbook market is already spiraling down.

How effective are Windows and Linux to exploit the real power this muliti core processors? If we were to write new applications, how effectively is it allowed by OS to employ many processors? Is it possible to quantify improvement in speed of application with increase in number of processors?

Well, there are a lot of workloads, where traditional superscalars beats gpu's. So it would be more practical to design such a general-purpose compiler for a cpu/gpu heterogeneous system. Actually this is what OpenCL is made for. And there is another important point. Gpu-like architecture tuned for general purpose workloads would be less effective for graphics.

I would be curious to know if there is any interest in using graphic processors for general purpose processing. It would seem to me that this would be an interesting marriage that might avoid the hybrid approach currently being pursued. I must confess to not having tried to use a GPU as a general purpose processor but in an earlier life I worked with array processors. The array processors could do general work (and often did) the difference was the compiler. Given the right compiler a Graphics Engine could perform as a general purpose computer, could the next big step forward not be hardware but software?

OK, AMD won't give benchmarks until Jan. launch but would say Zacate up to 80 to 90 GFlops, if that is meaningful.

AMD may sit on performance numbers until systems ship at CES, but I ask

What I'm itching to know is what the performance of the 9W 1.0GHz dual-core Ontario is versus Atom. If it's a lot faster, then we might have quite the 10" netbook platform on our hands.
