    This is for them, not you...
  • netdroid9, on 10/12/2007, -0/+11More like benchmarks.
  • cquinnd, on 10/12/2007, -0/+7I'll wait for the full announcement, but I'm hoping this will (at the least) have something to do with offloading performance for Directx10 and OpenGL processes on PCI-Express connected devices.
  • inactive, on 10/12/2007, -0/+4Actually, stream computing is meant for easy programming. It's essentially SIMD with an emphasis on caching. That is, the vectorsized codes are executed on the GPU, but in a manner that the data from memory is collected into a "stream" (buffer really) where data can be operated on in parallel. Look-up PeakStream and RapidMind for an idea of how this stuff is programmed; anyone with an understanding of MATLAB should be able to do it.
  • vuke69, on 10/12/2007, -0/+4It's probably more along the lines of video encoding, ray tracing, simulations, rc5-72, F@H, seti.

    In particular, anything with a tight loop, needing minimal external data, and that fits in the cache should be (stupid fast)*(number of pipelines)
  • inactive, on 10/12/2007, -0/+4Not on Linux it won't.

    I've already got my shiny new Nvidia card on order.
  • inactive, on 10/12/2007, -3/+5"...in some computing applications"

    Ultra-high-res, 3D porn?
  • fgsfds, on 10/12/2007, -1/+3... but only if it needs little more than 32bit-precision floating-point math.

    Which, considering how badly the x86 preforms at FLOPing, would be a welcome boon indeed.
  • NanoStuff, on 10/12/2007, -0/+1It's dual channel all over again!
  • KCorax, on 10/12/2007, -0/+1Until this is a free gain from GCC and Java or .Net JIT compilers I can't see it gaining momentum.
  • Atti2410, on 10/12/2007, -0/+0I am a little sceptical about all this. You can read my take on the subject here:

  • LordSkywalker, on 10/12/2007, -14/+2This means nothing when even now programs can't utilize the performance power of high-end processors.
