  1. North Carolina State University researchers have discovered a method of boosting processing performance by more than 21%. Although many processing designs by Intel, AMD and ARM house CPU and GPU…

    Sounds good. But, am I understanding this correctly. This is exclusively for gpgpu tasks? It frees up resources on the gpu so it can crunch faster? It'd be nice if it could intelligently do this on every program. Serial tasks for the cpu and parallel ones on the gpu.

    "To achieve the 20% boost, the researchers reduce the CPU to a fetch/decode unit, and the GPU becomes the primary computation unit. This works out well because CPUs are generally very strong at fetching data from memory, and GPUs are essentially just monstrous floating point units. In practice, this means the CPU is focused on working out what data the GPU needs (pre-fetching), the GPU?s pipes stay full, and a 20% performance boost arises."

    To boot, it was all done in a processor "simulator," not on actual hardware.

    Yes it would be interesting on what basis they can judge a speed increase when using a simulator.
  5. Would it make sense to design a group or system of chips one general cpu and the others designed for specialized tasks? The CPU is the brains and farms out the hard work to the specialized tasks. Or does it make more sense to do what we have been doing and just add more general cpu cores? And/or is the answer really in how the software deals with the hardware and that by writing better multitasking software we can get better performance?
  6. Maybe
    AMD needs to develop its own compliers to Windows or even Android OS so to maximize utiltztions of its own special chips. Is AMD still relying on Intel's compliers ?
  7. AMD has had it's own compiler (a customized version of GCC) for years. AMD has never relied on intel's compiler.
