Product information: ATI Radeon HD 3870 X2 1024MB GDDR3 TV-Out/Dual DVI/HDMI (PCI-Express) - RetailAdvance to ultimate HD gaming with incredible performance, life-like graphics and support for Microsoft® DirectX® 10.1. With dual ATI Radeon™ HD 3870 GPUs working in exquisite precision, you’re ready to dominate the battlefield from over one teraFLOPS of GPU compute power. And thanks to plug-and-play ATI CrossFireX™ upgradeability, you can scale your performance to even greater heights. ATI PowerPlay™ technology first used in ATI Mobility Radeon™ notebook GPUs has been built into the ATI Radeon™ 3800 Series GPU. This exciting break-through technology delivers further on AMD’s commitment to reducing the energy consumption in computing technologies. The technology is designed to enable power saving profiles that help reduce power consumption when the GPU is idle or in minimal use in comparison to previous products. This dynamic power management enables the GPU to automatically adjust power between low, medium and high states. It can alter the engine and memory clocks, as well as the voltages based on the software application’s activity level. Connect your PC to your home theater and start watching HD content from your computer using new ATI Radeon™ HD 3800 series graphics cards. The ATI Radeon™ HD 3800 Series is designed to decode and playback Blu-ray™ and HD DVD formats using dedicated hardware within the GPU. This technology, known as UVD or Unified Video Decoding, is part of ATI Avivo™ HD, the new collection of technologies that are designed to improve the visual and connectivity capabilities of ATI Radeon™ HD 3800 Series GPUs. UVD offloads the intensive process of HD video decoding and playback from the CPU while improving the visual quality. This means you can get smooth, high quality HD video playback from entry level PCs or free up the CPU for other tasks while you enjoy the movie. And with HDCP built into the GPU, the new cards easily enable playback of protected content. The ATI Radeon™ HD 3800 Series GPU further enhances the HD entertainment experience by making it easy to make the connection to a big- screen or home theater system. With built-in 5.1 surround audio (AC3) pass-through capabilities, the new GPUs and graphics cards support a single HDMI connection direct to a compatible TV or receiver. This single cable carries both the HD video and 5.1 surround audio for a clean, high definition connection. Some graphics cards will have an HDMI connector built in, while others will use a special ATI Radeon DVI-I to HDMI adapter. These options mean greater choice and flexibility for consumers when connecting to PC monitors or home theaters for maximum enjoyment of full HD 1080p content. New ATI CrossFireX™ multi-GPU technology takes your gaming experience to the next level with more scalability, performance and compatibility. The technology combines the awe-inspiring capabilities of multiple ATI Radeon™ graphics cards and an ATI CrossFireX ready motherboard to meet the hard-core demands of your alternate reality. New ATI Radeon™ HD graphics cards are designed with an internal ATI CrossFireX™ Bridge Interconnect system to simplify installation. Experience stunning visual realism in today’s demanding 3D games with uncompromising image quality, especially on HD displays. ATI CrossFireX: Multiply and Conquer!
