Last year there was a 2013 request, so why not for 2014. Last year's answer was basically nothing was planned at the time because of some difficulty with the amd drivers and we could support Donate gpugrid's sister project.

Now that donate seems to be dead is there any plans to revisit AMD gpus on gpugrid?

A guy can hope.

Yes AMD GPU's have power and are cheaper then nVidia's.
My old 5470 still outperforms a GTX690 on MilkyWay@home!
Would be very awesome if we could use them here. I think the programming is not that hard. You could contact Einstein@home. They are very skilled and very helpful.

Greetings from TJ

TJ, I don't think you can compare it like that. Milkyway was always faster on AMD GPUs. It's to do with the applications, running OpenCL i think.

Anyways, it would be nice with some AMD cards here, but I can understand the challenges facing it.

Well now that we know hoping for an OpenCL app here is pointless let's move on to the next phase which in 2013 was, IIRC, a pointless discussion about why CUDA is better than OpenCL and why AMD and Intel should just throw in the towel, bow before their NVIDIA masters and beg for license to use CUDA.

I found the answer to the third question in the FAQ at this site rather interesting. Renowned hi-perf parallel computing guru Wen-mei W. Hwu says in a nutshell that from a programmer's perspective OpenCL sucks and CUDA rules. So, AMD, on your knees, kiss the ring and repeat after me, "Oh great NVIDIA my liege, I your lowly and unworthy vassal do humbly beg for the privilege of using CUDA, a privilege for which I agree to pay 2,000 goats and 1,000 plump, plucked, poulets yearly."

Nope, that card can't run MW at all since it doesn't have any DP capabilities. You probably meant HD5870?
MrS

Low interest in OpenCL in the High Performance Parallel Computing industry tells me the industry sees less profit in OpenCL and more profit in CUDA. There must be a reason why they think that way. Maybe they're just "silly". Maybe they see CUDA as the least expensive and/or easiest path to a profitable product. Maybe NVIDIA pays kickbacks. When the more expensive GPUs use CUDA and the less expensive GPUs use OpenCL they must have a darn good reason for going with CUDA.

@Raymond: well, all GCN chips below Tahiti also crunch DP only at 1/16 SP, which is also crippled. Nvidia is not alone with this.

Do you know if the DP issue also applies to the R9 280X video cards as well?

Double precision performance of Hawaii is 1/8 of single precision performance,[19] Tahiti is 1/4 of single precision performance, others 28 nm chip is 1/16 of single precision performance.

Thought the R9 280X was a rebranded 7970.

Dagorath,

Thank you for your input and assistance and I have bookmarked those two links for future reference. I do not believe you are wrong about the R9 280X being a rebranded 7970.

Ray

Yes, the R9 280(X) is just a rebranded HD 7950/7970 (Tahiti Pro/XT). They belong to the Southern Islands family.
The R9 290(X) (Hawaii) is from the Volcanic Islands series and unfortunately these have the DP performance crippled to 1/8. So even though the R9 290(X) has more shaders, in DP it will perform worser than the Tahiti.

You're welcome. Ray. I like tables, lots of info all in one place.

OK, to be more precise ;-)
Hawaii-XT/PRO have the DPFP_RATE (Double-precision floating point rate) field of CC_GC_SHADER_ARRAY_CONFIG/GC_USER_SHADER_ARRAY_CONFIG registers set to 2, which means 1/4 of original DP performance (=1/8 of SP), where the workstation series have no such limit and the setting is 0 (=full), which means 1/2 of SP :-DD

You win! I can't out precise that one :-)
