AMD plans to really rub DirectX11 support into NVidia’s face at CES by launching a whopping 12 new DirectX11 GPU’s, six for desktops and six for mobile platforms.

The Radeon HD 5600/5500 (codenamed Redwood) series is expected to replace HD4600 series. The leaked information indicated that Radeon HD 5670 features 400 stream processors, GDDR5 memory, 128-bit of memory interface, DisplayPort/DVI/VGA ports, and support for Eyefinity technology.

Additionally, the Radeon HD 5400/5300 is reportedly designed to take the place of HD4550/4350. The above mentioned cards are expected to sell around or below US$90.

With NVidia waiting on Fermi for DirectX11 compliant and the recently announced delays, this could finally give ATI a chance to jump NVidia in marketshare.
