AMD EyeSpeed

The Northern Islands family of GPUs has a whole stable of video playback features, and in order to keep them all under banner AMD created the Eyespeed brand. Eyespeed will be the all-encompassing term given to all of the multimedia enhancing technologies such as pre / post processing, transcoding and HD playback within a unified ecosystem.

Eyespeed is split within two main spheres of influence: leveraging parallel processing for improved performance and video decoding through AMD’s UVD3.

UVD3; UVD2 on Steroids

As many of you probably already know, AMD’s Universal Video Decoder has been around for years and is known as one of the most capable video processing platforms currently available. UVD is now taking the next logical step forward with an expanded list of accelerated codecs in addition to the ones which were already compatible with past iterations.

One of the main features which have been added to the newly minted UVD3 is the ability to decode videos which use MVC encoding. As part of the H264 / MPEG-4 AVC codec, MVC is responsible for creating the dual video bitstreams which are essential for stereoscopic 3D output. Supporting this standard brings AMD’s GPUs the ability to process Blu Ray 3D movies through a HDMI 1.4a connector.

MPEG-4 Part 2 hardware acceleration for DivX and Xvid codecs has also been added but there is no mention made about the Nero Digital codec. For the time being, we’ll assume that Nero Digital acceleration will be added at a later date.

AMD’s main focus for these new graphics cards and for future products is to go beyond simply decoding HD content and instead add high end image quality improvements prior to the signal reaching the display. Through the use of the compute resources within a given system, additional pre and post-processing can be done before outputting an HD video stream.

AMD claims the additional processing their products can accomplish will significantly boost overall image quality whether it is for a simple upscale standard definition image or a true high definition video stream. The HQV benchmark is a highly, highly, highly subjective metric in which to determine image quality but supposedly the HD 6000 series will simply destroy the competition once all of its video processing features are enabled.
