The Club 3D MALTA: Radeon™ HD 7990 is an uncompromising masterpiece of breathtaking performance. As the world’s fastest and most advanced graphics card, it descends from generations of AMD Radeon graphics cards that wore the same crown. And with a heritage like that, you know what you’re getting: an unparalleled experience wherein gaming is everything... but not the only thing. All hail the new king.

Top PickMust HaveRecommendedGoedPerformanceApprovedPower

You deserve to play the world's most demanding games at the highest resolutions and maximun detail settings, never settle for less.

Engineered as the world's most advanced graphics, is the industries first 28nm GPU design. It features 6GB GDDR5 of RAM, and two of the world's fastest GPU's in a single graphic card, providing 4096 stream processors of raw power.

Equiped with the latest technologies, such as PCI-E 3.0 support, AMD Eyefinity Technology for gaming on three or more displays and the incredible efficient AMD ZeroCore Power technology. Gamers should never settle for anything less.

The Club 3D Radeon™ HD 7990 with the dual slot, three variable speed 80mm low noise fan blade design combined with high performance heatpipes promotes cooler running temperatures under load, which leads to quieter operation, and increases overclocking and performance potential. 

The metal backplate significantly improves the pcb strenght and reduces electrical noise.
Designed to push not only the boundaries of DirectX® 11 gaming, the GCN Architecture is also AMD's first design specifically engineered for general computing. Equipped with 64 compute units (4096 stream processors), each containing a scalar coprocessor, AMD's 28nm GPUs are more than capable of handling workloads-and programming languages-traditionally exclusive to the processor. Coupled with the dramatic rise of GPU-aware programming languages like C++ AMP and OpenCL™, the GCN Architecture is truly the right architecture for the right time.
Step beyond the confines of a single monitor and embrace the true potential of PC gaming with the ultra-high resolutions of AMD Eyefinity multi-display technology on the Club 3D Radeon™ HD 7990.

Supporting multiple independent display outputs simultaneously, AMD Eyefinity technology delivers innovative graphics display capabilities enabling massive desktop workspaces and ultra-immersive visual environments for the ultimate panoramic computing experience. 

AMD Radeon™ graphics hardware is built to support two key technologies: the DirectX® 11.1 API and a new way of designing GPU drivers called “Windows Display Driver Model 1.2” (WDDM 1.2).1 Together, these technologies enable a range of new features for Windows® 8 and supporting software.
1.Target-Independent Rasterization (DirectX 11.1 required)
TIR is a new rendering path that enables superior anti-aliasing performance in Direct2d-driven applications.

2. Native Stereoscopic 3D (DirectX 11.1 required)
Starting with Windows 8, stereoscopic 3D support will be implemented directly in the operating system with a standardized path for support in future games.

 3. D3D11 Video Playback Improvements
Today, a game’s video content and its interactive content operate on different DirectX levels. Whereas gameplay might be rendered via DirectX 10 or DirectX 11, videos are frequently rendered with DirectX 9. This mixture of API levels makes it difficult for game developers to efficiently implement both types of content, an issue that will be streamlined by the API unification that DirectX 11.1 provides.

4. Screen Rotation
Tablet users are no stranger to rotating their devices between portrait and landscape mode. Compatible AMD Radeon™ graphics solutions and the AMD Catalyst™ graphics driver will utilize WDDM 1.2 to ensure that behaviors like rotating tablets are delivered with optimal consistency.
5. Flicker-free Display Handoff
During the course of operating a GPU, users may have noticed their screen flickering when performing such tasks as: installing a new GPU driver, switching from integrated to discrete graphics, or exiting sleep/hibernate to resume the desktop experience.

Thanks to WDDM 1.2, the AMD Catalyst™ graphics driver may now be smoothly transitioned from one component of the OS to another, which will reduce or eliminate monitor blanking in these scenarios.

6. Optimized Power Consumption
A new mechanism called “DirectFlip” is designed to optimize power consumption for video playback and other full-screen scenarios. It accomplishes this by guaranteeing that alt+tab actions, or overlaid notifications, do not force the computer to perform an inefficient change of rendering modes.

Furthermore, DirectFlip provides optimized memory bandwidth requirements; intelligent management of idle and active power; and smooth transitions from full-screen applications to the desktop.

Support for this feature has been enabled in AMD Catalyst™, and will be available on AMD Radeon™ graphics products that support WDDM 1.2.

Multi Stream Transport (MST) Hub*

The Club 3D MST hub is a hub device that receives a DisplayPort™ 1.2 MST signal from the source device and splits up and routes the video streams independently to each display device. Using this type of configuration also allows the use of non DisplayPortTM 1.2 monitors. Non DisplayPort™ outputs, such as VGA, DVI or HDMI®, the Club 3D MST hub is DP++ and can actively convert the DisplayPort™ signal to the other types of display interface signals.

The MST hub compliments well the Radeon HD 7990, allowing to support of more monitors from the native 5 display support.
