Has anyone had sucess folding on ati 58** cards ?

I used to be big into this and have just started again, with a 260 gtx, havent bothered folding@cpu.

Im either buying a 470/480 or ati equivalent, but wondering what folding performance is like on ati cards, has it changed ? it used to be pathetic.

Would have thought ati's would be better due to lots more shaders !?
 
Well if you are buying a card primarily for folding then i reckon the 470/480 is a good choice if you don't mind the extremely high power draw and temps.

Unless something has changed recently folding sucks on ati cards, the code has been optimised and runs better on nvidia cards.

This is the field where nvidia cards really shine!
 
There is supposed to be a update coming out to help folding on ATI cards, have no idea when its coming out. Folding can run on ati cards, my 5850 gets just about 3500 ppd.

How is that correct ? The 85 only has half as many shaders so it should be half the folding performance of the 480 series ?
 
Another option seems to be 2 of the 275 combined psyx cards. these appear to be 275's with a 9800 built in ?

In which case that will give me 15kppd (per card) ?

The predicted real world ppd for the 400 series is 20k.
 
Forgive me for highjacking this but i dont get folding? do you get anything for it as it seems some people put folding at there no.1 priority when buying a new card.

Sorry if i sound ignorant i just dont get it?

Medical research, trying to help find out the causes to diseases like Parkinsons and cancer?
 
ah ok makes sense now but surely the programmers should make it more efficient on ATI gpu's as im sure with the right optimization it would do very well on ATI GPU's too.

^That aswell

Because that bench shows the GPGPU power of the two cards, since CUDA is after all a variant of GPGPU

CUDA is an API, just like Stream/OpenCL/DirectCompute. GPGPU just means general purpose computing on graphics processing units. It's just a vague term and covers ANY code running on a graphics card that is not directly graphics related. All that benchmarks shows is that ATI is faster in THAT application. If ATI were so much stronger in 'gpgpu' then they wouldn't get thrashed in both OpenCL based benchmarks that Anadtech ran.

Just like with graphics engines you will always find certain code that runs better on one brand or the other.
 
Being slower in OpenCL does not mean having slower GPGPU performance though

If you gamed on it for lets say 40% of the time, and then folded for 60% of it.

Doesn't matter what you do the other 60% of the time, if you are not actually using the PC it should not be a consideration
 
Ironic that its folding ability just makes its complete lack of efficiency in power and heat even worse.
