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!
Microsoft® DirectX® 11
World’s first DirectX 11 GPU with full Shader Model 4.0 support delivers unparalleled levels of graphics realims and film-quality effects.
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.
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.

PhysX Technology
NVIDIA® PhysX™ is the next big thing in gaming!Delivering physics in games is no easy task. It’s an extremely compute-intensive environment based on a unique set of physics algorithms that require tremendous amounts of simultaneous mathematical and logical calculations. The best way to get real-time physics, such as explosions that cause dust and debris, characters with life-like motion or cloth that drapes and tears naturally is with an NVIDIA®PhysX™-ready GeForce® processor. PhysX software is widely adopted by over 150 games, is used by more than 10,000 registered users and is supported on Sony Playstation 3, Microsoft Xbox 360, Nintendo Wii and PC. PhysX™ technology will take gaming to a whole new level.

Windows Vista®
Enjoy powerful graphics performance, improved stability, and an immersive HD gaming experience for Windows Vista. 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.
Shader Model 5.0
Shader Model 5.0 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 4.0® Optimizations
Ensure top-notch compatibility and performance for all OpenGL 4.0 application.

SLI™ Technology
Delivers up to 2X the performance of a single GPU configuration for unparalleled gaming experiences by allowing two graphics cards to run in parallel. The must-have feature for performance PCI Express graphics, SLI dramatically scales performance on 60 top PC games.
40nm Technology
Faster clocks, double the transistor density of earlier 40 nm technology. 40nm technology helped make GTX 460 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.
