Overview
55nm Technology Faster clocks, double the transistor density of earlier 65 nm technology. 55nm technology helped make HD 4550 series products the most advanced GPUs ever highest clocks speeds, incredible feature integration, full performance and precision all the time, and ability to take advantage of future, higher-speed memories.
ATI Avivo HD ATI Avivo HD continues to provide brilliant colors, sharp images, smooth playback of Blu-ray™ and HD DVD content, and now adds enhanced connectivity through DisplayPort™, HDMI with built-in multi-channel digital audio, and on some GPUs, Unified Video Decoding (UVD). UVD is designed to enable a cool and quiet media PC with low GPU and CPU power requirements and playback of full HD 1080p content.
Catalyst™ Control Center ATI’s all-new Catalyst Control Center goes far beyond traditional driver configuration software—it’s a feature-rich and stable 3D acceleration control application that puts you in complete command of your ATI visual processing unit (VPU). Catalyst Control Center offers exceptional graphics performance and visual quality for the ultimate in performance, stability, and innovation. Safe GPU overclocking, custom profiles, and assignable hotkeys are just a few of the many new features. You’ll also enjoy frequent updates, reliable customer service, and an interactive user feedback program, all backed by ATI’s technical confidence, industry-leading capability, and uncompromising commitment to creating your ultimate visual experience.

Microsoft DirectX 10.1 The power of DirectX® 10.1 with awesome performance, stunning visual effects, and more dynamic interactivity than ever before.Ensures the best performance and application compatibility for all DirectX® 10.1 applications. Microsoft® DirectX® 10.1 games, with stunning 3D graphics and shading effects.
Shader Model 4.1 Shader Model 4.1 adds support for indexed temporaries which can be quite useful for certain tasks.Regular direct temporary access is preferable is most cases. One reason is that indexed temporaries are hard to optimize. The shader optimizer may not be able to identify optimizations across indexed accesses that could otherwise have been detected. Furthermore, indexed temporaries tend to increase register pressure a lot. An ordinary shader that contains for instance a few dozen variables will seldom consume a few dozen temporaries in the end but is likely to be optimized down to a handful depending on what the shader does. This is because the shader optimizer can easily track all variables and reuse registers. This is typically not possible for indexed temporaries, thus the register pressure of the shader may increase dramatically. This could be detrimental to performance as it reduces the hardware’s ability to hide latencies.

PCI-E 2.0 PCI Express® 2.0 –Now you are ready for the most demanding graphics applications thanks to PCI Express® 2.0 support, which allows up to twice the throughput of current PCI Express® cards. Doubles the bus standard's bandwidth from 2.5 Gbit/s (PCIe 1.1) to 5 Gbit/sec.
RoHS Compliant As a citizen of the global village, GIGABYTE exert ourselves to be a pioneer in environment care. Give the whole of Earth a promis that our products do not contain any of the restricted substances in concentrations and applications banned by the RoHS Directive, and are capable of being worked on at the higher temperatures required for lead free solder. One Earth and GIGABYTE Cares!
HDCP Support High-Bandwidth Digital Content Protection (HDCP) is a form of copy protection technology designed to prevent transmission of non-encrypted high-definition content as it travels across DVI or HDMI digital connections.
HDMI Ready High Definition Multimedia Interface (HDMI) is a new interface standard for consumer electronics devices that combines HDCP-protected digital video and audio into a single, consumer-friendly connector.
Windows Vista™ Enjoy powerful graphics performance, improved stability, and an immersive HD gaming experience for Windows Vista. ATI Catalyst™ software is designed for quick setup of graphics, video, and multiple displays, and automatically configures optimal system settings for lifelike DirectX 10 gaming and the visually stunning Windows Aero™ user interface.
Screen-Cooling The extended heatsink makes the low profile PCB to standard ATX size. This stylish heatsink with special screen design uses the natural air flow in the case to cool down. Therefore, GIGABYTE Screen-Cooling technology provides customers the same high performance in the ultra silent environment. Furthermore, the extended metal cover is able to protect the VGA cable and provides a useful handling. This new “Screen-Cooling” technology creates both cooling ability and outlook. It also creates a new trend for cooling thinking.
