Although at present AMD Radeon HD 7000-series products based on GCN [graphics core next] architecture cannot take advantage of the DirectX 11.2 application programming interface that will become available with the release of Windows 8.1 “Blue” this fall, going forward Advanced Micro Devices plans to release a driver that will enable DX11.2 on current-gen hardware.

The DirectX 11.2 brings a host of new features to improve performance of games and graphics apps that were designed for the API. For example, Windows 8.1 includes a new Direct3D feature called tiled resources, which exposes a limited virtual graphics memory model to apps and thereby permits loose mapping between logical resource data and physical memory. This allows the creation of large logical resources that utilize small amounts of physical memory. This is useful with terrain in games, app UI and in many other cases.

Although current-generation AMD Radeon HD 7000/8000-series hardware based on GCN architecture can technologically support all DX11.2 capabilities, including tiled resources, the final spec of the API dictates different procedures than AMD assumed. As a result, formally the company cannot claim 100% compatibility with DirectX 11.2.

Laylah Mah, an AMD engineer who spoke with Heise Online web-site, stresses that all AMD needs is to update the driver for the current-generation hardware so to comply with Microsoft’s implementations of DX11.2 functionality. As a result, the Radeon HD 7000/8000 products based on GCN architecture will gain both features and performance in future DX11.2-compatible applications.

Ms. Mah implied that since graphics processor inside Xbox One is based on the GCN technology and will likely utilize DirectX 11.2 capabilities for performance and quality improvements, the existing graphics adapters should naturally support the same functionality.

Hurray, I'll love my 7970 cards even more in a couple of weeks!

Prove yourself with that. nVidia Kepler not even supports Dx 11.1 fully let alone advanced 11.2

Much faster but at what cost? GTX770 goes for $400-450 and can't beat $300 HD7970GEs by more than 5%. The alternative is paying more than double for GTX780 for 30-40% more performance at best. No thanks to either of those when 20nm is less than 12 months away. HD7970 overclocked proved to be in the top 4 fastest GPUs since it launched nearly 2 years ago. That's a remarkable achievement and even more so once you consider that 7970 cards paid for themselves with bitcoin mining.

AMD GCN Radeon 7000 series is future proof whereas Nvidia not. Nvidia wont even support Dx 11.1 let alone Dx11.2. Future games make good use GPGPU for computing various game effects like physics,AI etc. Which really struggle on nvidia Kepler for sure.

AMD stock is down because stupid nVidia lovers are a majority. Now is the time to buy AMD shares, as they're about to release 9000-series graphics cards, Steamroller CPUs, and AMD-powered Play station 4 and XBox 180 are coming out for Christmas. AMD is about to rise back out of the ashes like a phoenix against both nVidia and Intel.

sweet dream
AMD is just like Nokia and Microshit
Wrong management.

And what makes you so qualified to make such statements?

You can see Nokia is almost dead
Windows Phone 8 No body wants (see Market share)
and Windows 8 is not a success.
ATI GPU feature...
2+2 = 4 if you can add

So, despite the fact that many experts are praising Rory Read's new management style and strategies for AMD, YOU think the management is wrong.

You might want to read this article:

and this article:

Essentially, they are both saying that Read's strategy is looking very good.

Also, I guess all these hedge funds who are loading up on AMD shares are all stupid and making a big mistake, too (warning--terrible grammar alert!):

So AMD is not just like Nokia and Microsoft. It is already well into a turnaround unlike the other two.

You could be right
Good luck
