IDK why the amd core sucks so bad at F@H, probably because they ported some of it from the cuda based cores, but hopefully that will improve as they better learn to exploit the architecture.
How is it perfectly suited for folding?
It's a scheduling nightmare to get F@h working on AMD GPUs.

Far too many variables to fully utilize the architecture.

lol even if it was better it runs on a hardware minority (aka propiatory) it will never become mainstream

hmm, no one refuted the fact that the Mercury Playback Engine was built with CUDA, while ADOBE left AMD out all together. Why would such a big company like Adobe leave AMD behind? The answers are in the article I linked.

In folding, Nvidia > AMD cards. Fact.

Who cares about Bitcoin Mining, I mentioned FOLDING.

What is more popular on OCN?



Yes, I got pwned.

Read this carefully.

http://www.youtube.com/watch?v=De5N9IjUkNo

Want another example?

I converted a movie that is 1 hour and a half today to watch on my Ipod. The GPU usage was between 30% - 50%, it was going at 320FPS, and the whole thing was done in 6 minutes 30 seconds using Badaboom 2.0. And I even had HT OFF.

Your turn.
You did this without an Nvidia GPU? Oh...wait...

That's the issue, CUDA isn't open for any hardware manufacturer to use without licensing it. If this is to become a standard then it needs to be an open standard.

CUDA can only be used by Nvidia cards. That is why there are other standards because AMD and Intel want a piece of the market too. CUDA is just made to sell Nvidia GPUs. It serves no purpose to its competitors.

If you transcode, Intel Quick Sync is much, much faster and higher quality than CUDA.

Quick sync works on cpu other than intel's?

Last I checked Quick Sync is only supported by Sandy Bridge?

You have a 920, I have a 930, are we able to utilize it?

I use Badaboom to convert vids for my Ipod Touch, the quality is great, and it's done quite quickly.

Plus I use Adobe Premiere CS5 for editing.

Isn't AMD's APP only available on AMD cards? Or does AMD ensure compatibility with Nvidia cards?

As far as I can tell, all companies have their own proprietary software to get an edge over the others.

OpenCL is the closest thing we have to an Open Standard since both Nvidia and AMD can utilize it, but why hasn't it taken off?

All serious questions.

If you knew about the differences of the architecture you would should have actually said

AMD -> Integer -> Bitcoin Mining
Nvidia -> Floating Point -> F@H

Nvidia for now has the better Floating Point performance
AMD has the best Integer performance

It's only a matter of time
