CHATSWORTH, CA – September 30, 2008 – Diamond Multimedia (, a leading manufacturer of PC graphics cards, sound cards and communications products, launched today the ATI Radeon HD 4670 graphics card. The 4600 series of cards boast up to 3 times the performance of the previous generation of GPUs.

The Radeon HD 4000 series of GPUs delivers their superlative visual performance with a powerful new TeraScale engine that delivers high resolutions and fast frame rates. Unified Video Decoder 2 frees up the CPU for other tasks, especially the most processing-intensive content, including VC-1, H.264 and now MPEG-2. Take full advantage of Blu-ray functionality with dual-stream, picture in picture (PIP) capabilities. The ATI Radeon HD 4600 Series GPUs can upscale video display to 2560×1600 on dual-link monitors, which is almost twice the display resolution of 1080p displays. As with their predecessors, the Radeon 4000 series provides graphics support for the latest Microsoft DirectX 10.1 games and realistic 3D graphics and shading effects.

All Diamond video cards carry the Diamond guarantee of quality assurance.

Diamond is legendary in the PC video card business for its less than 1 percent return rate versus an industry average of approximately 10 percent. Diamond cards use superior connectors, cables and components, as well as undergo more thorough testing for heat susceptibility and durability.
