Position Based Fluids Demonstration

Imagine 10 years from now when the granularity on the little balls can be increased to sub-pixel. We would be approaching real-life physics in games.

If this could be judged as a similar benchmark, then a 7970GHz ed. could do it 3x faster, on 45FPS.

No way to directly compare, I'd hazard its possible to code this kind of thing for AMD's architecture so as to get a bit better performance from the 7970 than you could with the 680 as the nature of the processing of this type of effect tends to lend itself to AMD's architecture a bit better.

Most likely yea but 15-45fps is way off whats needed for adding it into a full on gaming scene. I like all these demo's as for the most part they are pretty cool but i would rather a demo showed me something that they are capable of bringing into a good game. Future tech always seems so far off for my liking. Hopefully with the arrival of the new consoles this kind of tech ain't to far off.

You'd probably get away with a less accurate, slightly lower update rate simulation for gaming use than that video - tho you'd still need quite a bit of compute power to make it feasible for realtime use ingame - taking the tomb raider beach map as an example as a ballpark figure for the kinda of granularity for ingame use you'd probably need a pair of GTX680s dedicated to simulating the ocean and another card about half the compute power of a 680 to handle the streams/pools/waterfalls inland/on the cliffs.

That fluid bench is rubbish.

For in-game it's enough. I was asking if there is a way to compare the OpenCL performance, if the gap is really that big.

Hydrophobia Prophecy does the best in-game water simulation just as Red Faction does the best physics. For anything more than that you'll need a dedicated card for physics/ai/whatever. Until that point, we're stuck. Crysis 3 eats CPUs cores for breakfast and it's "just some grass".
