Hi,

Intel, AMD and NVIDIA graphics cards all support OpenCL. You might have to install the proprietary graphics drivers for OpenCL support though. I had to do that on my AMD card but I play games so I'd have to install them anyway.

While this is a true statement, the Intel drivers for linux do not offer OpenCL on the GPU, avoid this for now.

AMD cards work the best in terms of OpenCL according to benchmarks, but their drivers on Linux are **** (they are improving but they aren't quite there yet). NVIDIA and Intel cards have better drivers. Unfortunately I can't find any benchmarks for OpenCL performance on Linux, because driver performance does play a part as well.

I use Nvidia based cards in my desktop & laptop, it works faster than using just the i7 but I can't really compare this to AMD based cards. Intel is out of the picture due to no OpenCL support on linux.

    - min 8GB RAM
    - i5/i7
    - amd?
    - 64bit Linux (obviously)
    - SSD (hmm, would be nice but too costly to replace a 2TB HB?)
    - OpenCL supporting graphics card
    - min 1GB graphics memory

    my main question refers to the graphics cards. Can someone
    enlighten me
    which cards work well with OpenCL?

    Also, other comments reg. the above lists are welcome


My desktop consists of an i7 with 16GB ram, NVidia card, mSATA SSD (boot disk) and 2 large SATA drives in mirroring mode and it still takes 15 to 30 seconds to process an image from my Nikon D00

Cheers
