Using OpenCL with the radeon driver to print Bitcoins ? is this posible?

[Qaridarium]

I love the radeon driver very much and i love bitcoins.

why not put it together?

What is the OpenCL Feature status of the radeon driver ?

Tom got his first OpenCL sample program running yesterday...

... which is pretty cool.

Radeon wiki:"8 Out of source tree, proof of the concept support at the moment, support will be through gallium See GalliumCompute. "

wen will openCL be in tree? instead of out of tree?

"6 Only partial OpenCL support is possible, support through vertex shaders. "

for the hd4000 series sure its theoretical possible but is there any work for hd4000 cards going on or do i need buy a newer card?

it would be very nice

r600 cards don't get openCL support???


BTW props to Tom

R6xx cards don't have the necessary hw to fully support the entire OpenCL API; it would be limited to a certain subset. R7xx can support OpenCL over the gfx pipeline. Evergreen is the first generation of hardware with a native compute pipeline.

@agd5f

thanks



a bit of topic but which card works well with FOSS drivers and will support OpenCL??. in other words what would you buy now

[agd5f]

Your best bet for OpenCL support is evergreen or newer.

The cheapest card to deliver good bitcoin performance (with the proprietary driver) is the 5830. The relative lack of ROPs doesn't affect mining. The most efficient dual-GPU card for mining is the 5970, and single-GPU card is the 7970, especially after undervolting the core and downclocking the memory.
