Fudo has tested out the Radeon HD 7990 and the GeForce GTX 680 in Windows 7 and Windows 8. Peformance is pretty much the same, but clearly the 7990 drivers have some issues with Windows 8.  A 7950 is also benched.

Certified Windows 8 drivers are already available for graphics cards from both sides, AMD and Nvidia. We decided to use the latest beta drivers that, although currently lacking certificates, promise better performance. We used dual GPU graphics cards because they put greater demands on the driver.

AMD has more price cuts for Fall for the Radeon 7000 series.  Anandtech has the details. I was talking to XFX today at the Trinity event about this for a bit.

It should come as no surprise then that AMD is continuing this campaign of public price cuts this fall with yet another round of price cuts. As part of AMD‘s preparations for future events AMD’s cheaper 7800 series card, the Radeon HD 7850, is receiving an all-but-official price cut to shore up the card’s competitive positioning.

Semiaccurate details AMD AWD technology.  Yes, they are going all wheel drive.  Ok, no, it is AMD Wireless Display.   

Currently, AWD uses a third-party software encoder to send a mirrored image of you PC’s primary display to your TV using the Wifi Alliance’s WFDisplay Standard. AMD demoed this ability at this year’s CES. The hope is to have a native hardware based solution ready by sometime in 2013. AMD is also aiming to integrate AWD controls into its Catalyst Control Center so you can manage the service from there.

Anandtech looks at the Clevo P170EM which includes AMD's HD 7970M, and also their Enduro switchable graphics.  It allows the discrete GPU to be turned off and integrated to be used instead to increase battery life.

Step forward to early 2012 and we got another update to PowerXpress 5.0 (note that PowerXpress is now only used internally by AMD and hasn’t been their marketing name since PX4.0) along with a rechristening: Dynamic Switchable Graphics was out and Enduro was in. If nothing else, at least it makes my job easier as Enduro is much more concise. There's also the fact that the GPUs are no longer "switching", as the iGPU is always running; now the dGPU is simply supplementing the iGPU when needed. Along with the name change, AMD added OpenGL and OpenCL support to the mix, and with their Zero Core Technology (which is also part of their 7000 series desktop GPUs—a case of mobile design influencing desktops) the need to keep a small portion of the chip alive (aka BACO: Bus Active Chip Off) was removed. OEMs could also ship with custom profiles for applications, so for example Dell might want all of their extra utilities to default to running on the iGPU.

Fudo reports on the new Powercolor Devil 13 Radeon HD 7990.  

As expected, the new Powercolor Devil 13 HD 7990 uses two Tahiti XT GPUs placed next to each other on a single PCB and pushed to work at 925MHz for the GPU and 1375MHz (5.5GHz effective) for a total of 6GB of GDDR5 memory (3GB per GPU). The new Devil 13 HD 7990 also features a dual BIOS switch button that pushes the GPUs up to 1GHz.
