GIGABYTE RADEON HD 4770

"Gigabyte Radeon HD 4770 review also featuring the Sapphire Radeon HD 4830. The Gigabyte Radeon HD 4770 has a 24% higher clock speed, 44% higher memory speed and the same 640 Pixel Shaders as the Sapphire Radeon HD 4830. The Gigabyte Radeon HD 4770 does have a disadvantage which is the 128Bit Memory Interface which is half that of the Sapphire Radeon HD 4830. Will the advantages outweigh the disadvantages?"

GIGABYTE RADEON HD 4770

"The Gigabyte Radeon HD 4770 graphics processing unit (GPU) offers an unbeatable combination of HD gaming performance and price. Featuring the industry’s cutting-edge 40nm process technology and the most advanced GDDR5 memory technology, this GPU delivers seamless frame rates with incredible speed and processing power. Proof that high performance gaming and price can co-exist without compromise."

GIGABYTE RADEON HD 4770 FEATURES

40NM TECHNOLOGY

"Faster clocks, double the transistor density of earlier 55 nm technology. 40nm technology helped make HD4770 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."

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."

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 of the shader may increase dramatically."

OPENGL3.0® OPTIMIZATIONS AND SUPPORT

"Ensure top-notch compatibility and performance for all OpenGL 3.0 application."

CROSSFIRE

"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."

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!"

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."

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."
