Microsoft DirectX 11

"The power of DirectX 11 with awesome performance, stunning visual effects, and more dynamic interactivity than ever before.Ensures the best performance and application compatibility for all DirectX 11 applications. Microsoft DirectX 11 games, with stunning 3D graphics and shading effects."

Shader Model 5.0

"Shader Model 5.0 adds support for indexed temporaries which can be useful for 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 3.1 Optimizations

"Ensure top-notch compatibility and performance for all OpenGL 3.1 application."

CrossFireX

"Upgrade to even greater 3D performance quickly and easily thanks to plug-and-play ATI CrossFireX multi-GPU technology."

PCI-E 2.1

"PCI Express 2.1 Now you are ready for the most demanding graphics applications thanks to PCI Express 2.1 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 promise 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 designed to prevent transmission of non-encrypted high-definition content as it travels across DVI or HDMI."

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."

Microsoft Window 7

"Microsoft Windows 7 is the next generation operating system that will mark a dramatic improvement in the way the OS takes advantage of the graphics processing unit (GPU) to provide a more compelling user experience. By taking advangate of the GPU for both graphics and computing, Windows 7 will not only make todays's PCs more visual and more interactive but also ensure that they have the speed and responsiveness customers want."
