AMD has unveiled the ATI Radeon HD 5770 and ATI Radeon HD 5750 graphics cards, adding two more models to its suite of graphics cards to fully support Microsoft Direct X 11 technology and ATI Eyefinity multi-monitor support.

ATI Radeon HD 5700 graphics cards deliver more than 1 TeraFLOPS of compute power, ensuring performance in the latest DirectX 11 games, and in DirectX 9, DirectX 10, DirectX 10.1 and OpenGL titles.

The new cards feature a graphics core built on 40nm process technology and up to 800 stream processors. ATI Eyefinity technology enables up to three monitors to be used with a single ATI Radeon HD 5770 or ATI Radeon HD 5750 graphics card.

The company said that the new features and functionality of ATI Stream technology allow users to harness both AMD CPUs and the ATI Radeon HD 5700 series graphics cards to maximise their computing experience, helping to improve the performance of enabled media, entertainment and productivity applications.

ATI Stream technology and the HD 5700 series support both DirectX 11 Direct Compute and OpenCL industry standards. The new series also supports the latest HD audio technologies such as Dolby TrueHD, DTS-HD Master Audio and HDMI 3.1 and reportedly consumes 16 watts at idle.

Rick Bergman, senior vice president and general manager of AMD Products Group, said: “The ATI Radeon HD 5800 series reaffirmed AMD as the undisputed leader in visual computing technology. Now, the ATI Radeon HD 5700 series takes the same great features like ATI Eyefinity and ATI Stream technology as well as full hardware support for all DirectX 11 features, and bundles them into products priced well below $2002.”

The ATI Radeon HD 5700 series and ATI Radeon HD 5800 series of graphics cards are supported by add-in-board companies, including ASK, Asus, Diamond, Gigabyte, High Tech, MSI, Sapphire, Tul/Power Color, Visiontek and XFX.
