Latest technology in games


The Club 3D Radeon™ HD 7850 royalKnights graphic cards are intended for gamers who never settle. Equipped with AMD Graphics Core Next Architecture and the latest power management technology, the Club 3D Radeon™ HD 7850 royalKnights is primed to enable astonishing performance and breathtaking image quality, making it the only solution for gamers who demand the best.


Windows 8The Club 3D Radeon HD 7850 royalKnights takes full advantage of the features that Windows 8 has to offer with the Radeon HD 7000 series GCN architecture. Video and picture editing software and games are already reaping the benefits of Windows 8 and GCN architecture family of graphic cards. Game and application developers are including GCN optimizations in their software, take Adobe Photoshop and Corel WinZip for example, these applications receive a performance increase of by up to 25% on the Windows 8 operating system** using GCN optimization.


Windows 8 is also great for multi-monitor solutions with its new easy to use taskbar. A new feature of Windows 8 is that the taskbar is now available on each screen, which can boost productivity by up to 35%.

(**) Performance increase on Windows 8 when compared versus Windows 7


Starting with the Radeon HD 7000 Series, Radeon graphic 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). Together, these technologies enable a range of new features for Windows 8 and supporting software.


TIR is a new rendering path that enables superior anti-aliasing performance in Direct2D-driven applications. These include the Windows® 8 UI, as well as the market’s variety of graphics-accelerated browsers: Google Chrome, Internet Explorer and Mozilla Firefox. DirectX 11.1 enables this by allowing the GPU to stand in for the processor during the anti-aliasing stage, and the result is a sharper and clearer dynamic interface that better retains ideal performance.


AMD HD3D technologyNow with more than 600 supported titles*, AMD HD3D technology has provided gamers with an immersive gaming experience through stereoscopic 3D depth. Starting with Windows 8, stereoscopic 3D support will be implemented directly in the operating system with a standardized path for support in future games.

Provided a user has a fully 3D-enabled display chain (GPU, driver and display), users will see evidence of this native functionality in the control panel settings.

(*) Native supported AAA game titles:


AMD App Acceleration technologyToday, 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.

This unification also provides hardware-accelerated video that’s on par with DirectX Video Acceleration (DXVA), the software library that AMD’s App Acceleration technology already uses to deliver the world’s best video playback quality to AMD Radeon™ customers.

One practical implication of these improvements could be the inclusion of more and higher quality video cutscenes in tomorrow’s games. Another implication might be improved video transcode performance, which AMD also offers across its full line of available Radeon™ Graphics products.

In tests conducted by AMD as of 20 July, 2012, the Radeon™ HD 7000 Series obtained the highest HQV 2.0 score* of any tested system. HQV 2.0 is an industry benchmark used to evaluate video playback quality.

(*) Tested on: Radeon™ HD 7970 (200/210), GeForce GTX 680 (192/210), GeForce GTX 580 Series (182/210), Intel Core i7-3770k (197/210) and Intel Core i7-2600k (182/210). HQV 2.0 provides visual feedback for scoring by the reviewer. Scores may vary based on the skill and opinion of the reviewer.  All machines were tested using a 40" Sony Bravia HDTV connected via HDMI, at 1920x1080p resolution via Cyberlink PowerDVD 10. System configuration: AMD Athlon™ II X2 260u (1.8GHz) and AMD 890G for NVIDIA and AMD Radeon™-based system(s). Intel Z68 chipset utilized for Intel systems. Drivers: 8.981.2 (AMD), (i7-2600k), (i7-3770k) and 304.42 (NVIDIA).

Eyefinity 2.0EYEFINITY 2.0

Eyefinity™ 2.0 Technology features all-new support for Stereo 3D, universal bezel compensation and brand new display configurations which allows the user to configure custom resolutions and the ability to relocate the Windows task bar to an arbitrary screen.




The next step in audio output from a graphics card. Traditionally video cards has been able to output audio through the HDMI port and audio has been restricted to to a single device, be it a monitor, HDTV or a receiver.

With DDMA now you can send audio to multiple devices via the DisplayPort combined with the HDMI.

Imagine a video conferencing where each attendee is mapped to a monitor and with DDMA set on each monitor speaker set.



A revolutionary new architecture. Jump right into GPGPU applications today with Microsoft C++ AMP™ and OpenCL™ for spectacular performance with the GCN architecture. From video editors to Internet browsers, AMD App Acceleration™ is a supercharger for everyday applications. The Club 3D Radeon™ HD 7850 royalKnights was engineered for the GPU revolution in compute.




AMD is introducing with the Southern Islands chipset their long idle power saving technology. Now the graphics card can turn off most of its functional units of the GPU, when they are unused, leaving only the PCI Express bus and other components active. This as a result, reduce the power consumption from 15W at idle to under 3W in long idle, a power level low enough that ZeroCore Power shuts off the fan as there is no heat generated further saving energy.

ZeroCore Power will put CrossFire™ grapics cards in ZCP when not in use.


AMD HD3D™ is a technology designed to enable stereoscopic 3D support in games, movies and/or photos. Additional hardware (e.g., 3D-enabled panels, 3D-enabled glasses/emitter, Blu-ray 3D drive) and/or software (e.g., Blu-ray 3D discs, 3D middleware, games) are required for the enablement of stereoscopic 3D. Not all features may be supported on all components or systems—check with your component or system manufacturer for specific model capabilities and supported technologies. AMD HD3D™ technology is enabled on AMD Radeon™ HD 7000 Series GPUs and above using Catalyst 12 or later.




AMD PowerTune technology is a very significant leap forward to better ensure that performance is optimized for TDP constrained GPUs. AMD PowerTune technology helps deliver higher performance that is optimized to the thermal limits of the GPU by dynamically adjusting the clock during runtime based on an internally calculated GPU power assessment. AMD PowerTune technology also improves the mechanism to deal with applications that would otherwise exceed the GPU‟s TDP. By dynamically managing the engine clock speeds based on calculations which determine the proximity of the GPU to its TDP limit, AMD PowerTune allows for the GPU to run at higher nominal clock speeds in the high state than otherwise possible. AMD PowerTune technology is very different from existing methods; rather than setting highest state GPU clock speeds based on a worst case TDP approach that can compromise performance in a majority of applications, AMD PowerTune technology can dynamically adjust the performance profile in real time to fit within the TDP envelope.


AMD Radeon™ GPUs with AMD App Acceleration let you run multiple applications at the same time with remarkable speed and reliability. AMD App Acceleration can help reduce slowdowns and stuttering in intensive, media-rich applications. Powered by a set of innovative hardware and software technologies working in concert behind the scenes, AMD App Acceleration gives you enhanced speed and performance beyond traditional graphics and video processing. You can multitask more efficiently, and more confidently.


4 years after the introduction of PCI-E 2.0, the all new PCI-E 3.0 specification is now introduced. Providing 1GB/sec per lane bidirectional, which for a X16 device means 16 GB/sec, doubling 8 GB/sec on the previous generation.

HDMIFAST HDMI technology

With the introduction of the HD 6000 Series, HDMI 1.4a implementation allows the graphics card to enable Stereo 3D on HDTVs or monitor displays, this same feature is also found on the new HD 7850. Now with the introduction of HDMI support for 4K x 2K displays, the HD 7850 is now able to run 4K x 2K displays (max resolution 4096x3112) over HDMI along with being able to support 1080p Stereo 3D at 120fps (60Hz/eye), with the current standard set at 48fps (24Hz/eye).

Multi-Monitor, 21.6 Gbps bandwidth
