HDMI and Audio Feature Support
The ATI Radeon HD3800 series has a built in HDMI with HD audio support for one-plug HDTV connectivity. This unique feature is enabled with an intelligent DVI to HDMI adapter. The benefit of this approach is to preserve the traditional dual-DVI-I connectivity (with VGA support) that gamers demand while offering a seamless connection for big-screen HD gaming, No internal SPDIF or other audio cabling is required.
ATI CrossFireX Technology
New ATI CrossFireX multi-GPU technology combines the awe-inspiring capabilities of multiple ATI Radeon graphics cards and an ATI CrossFireX ready motherboard, to give you the next generation gaming experience.
- Internal ATI CrossFireX Bridge Interconnect system
- Overclockability on Multi-GPU
- ATI CrossFireX multi-GPU support for highly scalable performance, can allow quad ATI CrossFireX configuration with four ATI Radeon HD 3800 cards
- Native CrossFireX support is a new feature in the ATI Radeon HD3800 series, making the ASIC multi-GPU technology ready.
- Built-in Crossfire compositor and control for synchronizing parallel graphic processors in one system, as well as a new bi-directional Digital Video I/O Port (DVP) to provide interconnection.
Windows Vista with comprehensive DirectX 10.1 support
DirectX 10 is the first totally new DirectX technology, and brings important graphics innovations. It is a major inflection point for graphics. Now, the latest Microsoft DirectX 10.1 is compatible with DirectX 10 cards, and will replace DirectX 10 in Vista SP1. DirectX 10.1 supports the entire structure and programming model of DirectX 10, but also povides numerous enhancements. DirectX 10.1 advances the gaming to the next generation with incredible 3D performance and life-like graphics. It contains Shader Model 4.1 support, and it can make benchmark comparisons more significant with multi-sampling and anti-aliasing patterns features.
The ATI Radeon HD3800 series are the first GPUs which are especially designed for DirectX 10.1.
