Title: AMD and Nvidia OpenCL support question
Post by: SeW900 on July 18, 2011, 02:04:27 PM
There seem to be lots of different articles (some new, some old) so I can't seem to understand the current requirments for running a OpenCL miner.

- Do Nvidia GPU's (8000 series and up) require any additional software/drivers besides the basic normal Nvidia WHQL drivers?
- Do AMD cards still require AMD stream or AMD APP to be installed in order to work? Seems poclbm users say that AMD Stream is a must, while ufasoft can use AMD cards only with the Catalyst drivers installed?

- Finally, if correctly installed, do all CPU's (even PIII's) support and work with OpenCL?

I know I've posted many questions, but I'm very confused at the moment :D

- i mined with my geforce 8000 series only with installing default driver
- on windows amd app sdk is installed automatically, so no need to worry about it
- on ubuntu i had to install it to get phoenix miner working

PIII is a waste of energy i think

With NVIDIA or AMD GPUs on Windows or Linux, just install the latest drivers from nvidia.com or amd.com and it will just work. If you want to run on CPUs, you may want to try OpenCL drivers from both AMD and Intel and see which is faster (you can use Intel-OpenCL on AMD CPUs or AMD-OpenCL on Intel CPUs - they should mix fine). But I would think non-OpenCL CPU miners are faster (being based on hand-optimized assembly code).

Mining on Apple products you are out of luck, because Steve Jobs as usual insists on making the drivers himself. You will have drivers that are old and full of bugs that were fixed on Windows and Linux a long time ago. But other than that, it may work ok. ;)
