**Edit**

made some new videos using the educational mode.

The Ladybug demo shows the results of a new approach to simulating lens-accurate depth-of-field effects based on real-world parameters of focal length and focus distance. This technique is made possible by the ATI Radeon™ HD 5000 Series of graphics processors and the Microsoft® DirectX® 11 and Direct Compute 11 technologies. Depth-of-field is used in feature films by cinematographers to subtly guide a viewer’s attention through a shot or to heighten the emotion of a scene. This technique finally provides developers with a way to achieve the same effects and bring new levels of cinematic realism to their games. This approach is enabled by features such as atomic operations and shared memory.

The Mecha demo shows the results of a new approach to rendering semi-transparent objects without pre-sorting, known as order-independent transparency (OIT). It is made possible by the ATI Radeon™ HD 5000 Series of graphics processors and the new features of Microsoft® DirectX® 11 technology. Blending is an order-dependent operation that requires sorting objects before rendering them. Atomic operations and append buffers make it possible to construct per-pixel fragment lists and sort them on the GPU. The results are a significant increase in speed and accuracy over those possible with traditional techniques.

Nice. But I don't see anything spectacular about it. Is there something technical about the ladybug demo I'm missing?

Seems rather tame compared to say 3dmark vantage stuff.

Its a tech demo so what more do you want? its free

Nvidia and ATI both have a library of tech demos demonstrating new gpu features.

Each time a new series of cards comes out so do tech demos.
