GIGABYTE RADEON HD 5770 REVIEW

"Gigabyte Radeon HD 5770 review also featuring the Gigabyte Radeon HD 4770. The Gigabyte Radeon HD 5770 uses the RV850 GPU running at 850Mhz with 1GB Gddr5 Memory at 4800Mhz with 800 Shader Processors with DX11. The Gigabyte Radeon HD 5770 has 12% faster Core Clock, 34% faster Memory Clock and 20% more Shader Processors compared to the Gigabyte Radeon HD 4770. The Gigabyte Radeon HD 5770 is also more advanced than the Gigabyte Radeon HD 4770 offering DirectX 11 Support while the Gigabyte Radeon HD 4770 has DirectX 10.1. The Gigabyte Radeon HD 5770 is more powerful but how much better is Gigabyte Radeon HD 5770 compared to Gigabyte Radeon HD 4770 which is 34% cheaper?"

GIGABYTE RADEON HD 5770 FEATURES

40nm Technology

"Faster clocks, double the transistor density of earlier 40 nm technology. 40nm technology helped make HD5770 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."

Microsoft Window7

"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."

Avivo HD

"Avivo HD could provide vibrant high fidelity, flawlessly smooth next-generation video playback. Avivo HD 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."

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 ability to hide latencies."

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."

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 2.0

"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."

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."

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."
