AMD 6800 Series Review

,    -   

Closer Look:

With the beginning of a new product generation comes new technologies that the generation supports. Many of the new features are based on older technologies supported from the prior generations with a fresh take aimed at improving the end user experience.













Eyefinity Demo:


With the new 6000-series graphics cards, each can support up to six monitors for an Eyefinity setup. Gamers are no longer stuck with using only a single monitor for game play as the games can now be spanned across multiple monitors and can also make use of the new 3D technologies explained further towards the bottom. Multiple displays can be powered by a single connector with Eyefinity and the ultra-high bandwidth DisplayPort 1.2 Multi-Stream output capabilities with high quality audio also being transmissible. Below is a demonstration of a triple-monitor Eyefinity setup with several different game examples to view either a classic single monitor setup or the new Eyefinity triple-monitor experience.



Morphological Anti-Aliasing:

Morphological anti-aliasing is a post-process filter that is accelerated with DirectCompute 11 and is able to filter the entire scene. MLAA is faster than super-sampling with similar performance to the older CFAA while being applicable to all edges of the scene. MLAA is compatible with applications using Microsoft DirectX versions 9, 10 and 11. Anisotropic Filtering has also been updated with a new algorithm for smoother transitions between filter levels and to address visible discontinuities in textures. MLAA processing takes highly contrasting edges and blends them for a more seamless render.



Accelerated Parallel Processing

AMD is making a shift by changing the naming scheme away from ATI to unify the company with its CPUs and GPUs. The name Accelerated Parallel Processing (APP) technology will replace the ATI Stream nomenclature in an effort to convey what it means more clearly. The core has been redesigned to improve efficiency and add new features and more power. OpenCL and DirectCompute 11 are both supported and help boost performance as well in certain applications that make use of these frameworks and allows the GPU to do parallel processing and non-GPU related tasks such as Physics calculations. Tessellation performance was focused on with the new design using an updated tessellation unit that can perform up to two times the 5000-series generation performance with adaptive capabilities to balance image quality and performance. Media playback and processing were also updated with a dedicated UVD 3.0 accelerator which provides decoding for Blu-ray 3D and DivX. AMD calls the combination of APP, UVD, OpenCL, and DirectCompute 11 "AMD EyeSpeed" technology.


HD3D technology

The 3D arena has been further expanded upon by AMD to support 3D Blu-ray playback with Stereoscopic 3D display/glasses and 3D Stereoscopic gaming and middleware support. Their goal is to increase flexibility and choices for 3D media, games, conversion and display technologies. Now users have several options available for a riveting 3D experience in games, movies and images.


With some of the new technologies debriefed, here it is time to take a look at the specifications and features of the graphics cards themselves.
