This Gigabyte GV-R489-1GH-B graphic card powered by Radeon HD 4890 GPU, 1GB GDDR5, supported for PCI Express 2.0, and featured Dual-link DVI-I, and HDCP; and supports for CrossFireX and Avivo HD technology. 55nm Technology Faster clocks, double the transistor density of earlier 65 nm technology. 55nm technology helped make HD4870 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. Avivo Avivo could provide vibrant high fidelity, flawlessly smooth next-generation video playback. Avivo technology easily allows your PCs to become digital home media center by its compelling video pipeline design that comprises the latest high definition video hardware acceleration, including H.264 and WMV9. 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. OpenGL 2.1 Optimizations and Support Ensure top-notch compatibility and performance for all OpenGL 2.1 application. Cross Fire Multiply and Conquer with Multi-GPU Performance: CrossFire’s “supertiling” GPU sharing speeds rendering by evenly dividing the graphics processing, intelligently alternating the rendering workload to each Radeon GPU for efficient load balancing, and optimized performance.CrossFire boosts image quality along with rendering speed, eliminating the need to crank down screen resolutions to get the high image quality you want.CrossFire supports a wide range of ATI-based graphics cards and motherboards, and offers compatibility with a broad array of third party components for a flexible and robust solution. 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.
