Hello list,
It's approaching time to invest in a new system, and I'd like the panel's
views on which make of graphics card to choose: AMD, nVidia or Radeon. I
don't want to start a flame war, but which of those would give me the best
performance in GPU calculations? I have some BOINC projects in mind, which
apparently are greatly accelerated by using GPUs as well as CPUs.
The nouveau driver for nVidia can't do CUDA (GPU) calculations so I'd have
to use the nVidia driver; I don't know about the others which is why I'm
asking.
Does anyone here have an opinion to offer?
If you need 64-bit FP compute, AMD Radeon is your only choice. NVidia
only supports 32-bit FP and cripples 64-bit FP on consumer cards,
rendering them virtually useless; you'd have to buy a "professional"
card (thousands of dollars).
So you might want to check whether your applications need 64-bit FP or
32-bit.
