ATI Radeon HD 5970 2 GB dual-GPU card claims title as fastest discrete card in the world

In the short span of two months, AMD has launched five DirectX 11/OpenGL 3 cards ranging in price from $150 to $600, each setting the performance title per price point. The latest is the dual-GPU powered Radeon HD 5970. In addition to unrivaled performance, the 5970 supports full DirectX 11, ATI Eyefinity multi-display technology, the latest UVD engine, is overclockable, offers the best game image quality of any graphics card and is power efficient for it's performance level (but still potentially hungry).
AnandTech summarizes it nicely:
There are two things that become very clear when looking at our data for the 5970
- It’s hands down the fastest single card on the market
- It’s so fast that it’s wasted on a single monitor
Demos of DirectX 11 on the new Radeon HD 5800 series

AMD Developer Central has some new demos which show off the Radeon HD 5800 series cards and DirectX 11.
The Mecha demo shows the results of a new approach to rendering semi-transparent objects without pre-sorting, known as order-independent transparency (OIT). 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.
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 using Direct Compute 11. 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.

Less than 20 days to the launch of DX1 and Windows 7, and another video from Siggraph 2009 is now online:

AMD announces open physics initiative built around OpenCL or DirectCompute and Bullet Physics

AMD and announced a joint development agreement as part of the AMD effort to greatly expand the use of real-time physics with graphics through the open source Bullet Physics engine using OpenCL and/or DirectCompute in DirectX 11.
A great quote from the release: “Proprietary physics solutions divide consumers and ISVs, while stifling true innovation; our competitors even develop code that they themselves admit will not work on hardware other than theirs”
AMD ATI Radeon HD 5850 - more affordable and economical version of 5870

A week after the introduction of the ultra-powerful, DirectX 11-ready Radeon HD 5870 ($379), several sites are reporting on its more affordable (at $259) , lower-power-consumption, cousin, the Radeon HD 5850. The reviews are again pretty rave. It shares the same basic features as the Radeon HD 5870 including DirectX 11 support, Eyefinity multi-display technology, and new anti-aliasing and anisotropic filtering modes. The new card has fewer stream units (1440 vs 1600), fewer texture units, and lower clock speed.
How does it perform? To quote Hexus.net “What AMD/ATI has accomplished with the Radeon HD 5850 GPU is the distillation of the range-topping goodness in an eminently sensible fashion”
ATI DirectX 11 Eyefinity “Evergreen” card (aka Radeon HD 5870) is out

The Radeon HD 5870 cards are official today (press release) and the reviews are out everywhere. The new card features full DX11 support including DirectCompute, OpenCL support, of course OpenGL support, Eyefinity multi-monitor support and doubling of performance over previous cards with up to 2.72 TeraFLOPS of compute power.
Some of the many reviews:
No word yet on any professional level cards like the FirePro line, but those typically takes more time since there is an involved process to certify the drivers for high performance (and warranty) in CAD apps.
