HD High-definition video and display technology for ultimate home theater enjoyment. Advance HD image processing, delivering cool and quiet full-spec HD disc playback with hardware-based Unified Video Decoding (UVD) capability, built-in HDMI with multi-channel HD surround audio, and support for high-quality connectivity with multiple HDTVs and displays.

ATI HyperMemory
HyperMemory™ is ATI’s innovative technology that enables a reduction in the amount of on-board memory on a graphics card without compromising its overall performance. Its advanced memory management technology makes more efficient use of all the available memory in computers with PCI Express® technology. Graphics applications can share system memory and use fast on-board memory for real-time processing between the graphics card and the computer’s memory. This ultimately increases the affordability of Radeon graphics technology.

ATI PowerPlay
Technology that improves the energy efficiency of Radeon™ graphic cards. Designed to enable power saving profiles that help reduce power consumption when the graphics card is idle or in minimal use. This dynamic power management enables the graphics card to automatically adjust power between low, medium and high states for a tremendous power efficiency advantage. For example, when receiving and composing emails little demand is on the graphics card so it runs in a low state, whereas when gaming, there is high demand on the graphics engine and the graphics card runs in a high state.
