Enhanced UVD 2.0 | ATI Stream | Eyefinity

Universal Video Decoder 2.0

Always worth a mention is UVD, short for Universal Video Decoder. With proper 3rd party software like WinDVD or PowerDVD you can enable support for UVD 2.0 which provides hardware acceleration of H.264 and VC-1 high definition video formats used by Blu-ray and HD DVD. The video processor allows the GPU to apply hardware acceleration and video processing functions while keeping power consumption & CPU utilization low.

You will have sheer decoding precision on the Radeon 5000 series. Low CPU utilization whilst scoring maximum image quality. One improvement has been made as well; you can now for example upscale your 1920x1080 streams fine to a 2560x1600 sized monitor (no more black borders).

New in the GPU architecture of the series 5000 is an updated video engine. It's really not massively different opposed to the old UVD engine, yet has two new additions for post-processing, decoding and enhancing video streams. Dual stream decoding is one of the new features. For example, if you playback a Blu-ray movie and simultaneously want to see a director's commentary (guided by video) you can now look at both the movie and in a smaller screen see the additional content (like picture-in-picture). Obviously this is Blu-ray 2.0 compatibility here, and the additional content is an actual feature of the movie. But definitely fun to see.

New in Enhanced UVD 2.0

  • Hardware acceleration decode of two 1080P HD streams
  • Compatible with Windows Aero mode - playback of HD videos while Aero remains enabled
  • Video gamma - independent gamma control from Windows desktop.
  • Brighter whites - Blue Stretch processing increases the blue value of white colors for bright videos
  • Dynamic Video Range - Controls levels of black and white during playback

A recently added feature also is Dynamic Contrast Enhancement. It does pretty much what the name says; Dynamic Contrast Enhancement technology will improve the contrast ratios in videos in real-time on the fly. It's a bit of a trivial thing to do, as there are certain situations where you do not want your contrast increased.

Another feature is Dynamic Color Enhancement. It's pretty much a color tone enhancement feature and will slightly enforce a color correction where it's needed. We'll show you that in a bit as I quite like this feature; it makes certain aspects of a movie a little more vivid.

Directly tied to the UVD engine is obviously also sound. AMD's Radeon series 3000, 4000 and 5000 cards can pass lossless sound directly through the HDMI connector. This has been upgraded as it's now possible to have 7.1 channel lossless sound 192kHz / 24-bit. The HDMI audio output follows HDMI standard 1.3a and now also supports Dolby True HD and DTS-HD audio. Obviously there is also support for standard PCM, AC-3 and DTS.

To be able to playback high-def content you'll still need software like WinDVD or PowerDVD, a HD source (Blu-ray player) and a HDCP monitor or television.

For those interested in MKV / x.264 GPU based content acceleration, playback and image quality enhancements, please read this guide we have written. We spotted this lovely little free application to manage this.

ATI Stream

In the current day and age there is more to graphics cards than just playing games. More and more non-gaming related features can and are being offloaded to the GPU. Roughly a year ago ATI introduced ATI Stream. This is a software layer that allows software developers to 'speak' with the GPU and have it process data using your graphics card. This really is the most simple & basic description I can give it. I have no idea where ATI Stream will be heading now that DirectCompute is available.

In this article we'll show you a test where we utilize ATI Stream and NVIDIA CUDA to transcode videos over the GPU.

Now I'd like to point you towards one function you should all do with your GPU when it's doing nothing.

Folding@home using the ATI Radeon series 5000 GPU
Folding at home is a project where you can have your GPU or CPU (when the PC is not used) help out solving diseases, folding proteins. Over the past 12 months a lot of progress has been made between the two parties involved. And right now there is a GPU folding client available that works with Radeon 5000 series graphics processors. It is ATI Stream based, meaning that all Stream ready GPUs can start folding.

Guru3D team is ranking in the Folding@Home top 90, yes... I'm very proud of our guys crunching these numbers, especially since there are tens of thousands of other teams. The client is out, if possible please join team Guru3D and let's fold away some nasty stuff. The good thing is, you won't even notice that it's running.

Our Folding@home info can be found here:

Our Guru3D team number is 69411 and if you decide to purchase a 5000 series product, guys, promise me you'll use it to fold for us. By making this move my dear friends, there are now 70 million GPUs available to compute the biggest mysteries in diseases and illnesses. Again, let's make Team Guru3D the biggest one available guys, join our team.

ATI Eyefinity

A new and exciting feature for ATI Radeon series 5000 graphics cards is ATI's Eyefinity. ATI introduces Eyefinity technology on their Radeon HD 5000 series graphics cards. This literally boils down to multi-monitor desktop and gaming nirvana! You will have no problem connecting say, three 30" monitors at 2560x1600. The graphics card can take that resolution and in fact combine the screen resolution and play in it, though with a 5700 you will lack the horsepower needed to drive modern games in such resolutions. Three times 1280x1024 however would do pretty well.

We can explain this technology really simply though; you guys remember our Matrox Triplehead2Go reviews right? Well, ATI's Series 5000 graphics cards will be able to drive one to six monitors per graphics card. We've seen and tested this live in action, and it works really nicely. You can combine monitors and get your groove on up-to 7680x3200 pixels separated over several monitors -- multiple monitors to be used as a single display. I think the limit is even 8000x8000 pixels, but don't hold me to that.

So some examples of what you can do here:

  • Single monitor setup at 2560x1600
  • Dual monitor setup at 2560x1600 per monitor
  • Three monitors setup at 2560x1600 per monitor
  • Six monitors setup at 1920x1080 per monitor

Eyefinity is looking really nice, and sure we also understand that 99% of you guys will never use more than two monitors. That other 1% definitely matches the Guru3d audience. Personally I like to game on three screens. It's really immersive.

Mind you that for six monitor support, a special edition (Eyefinity6) card will be launched with six display ports. Your average Radeon HD 5700/5800 series card will have three or four monitor outputs. In fact the reference cards have two DVI, one HDMI and one display port connector all on one card. If you are bold enough to go for a multi-monitor setup, it really is ideal to get three screens for flight sims, racing games, role paying games, real-time strategy, first-person shooters and sure, even multimedia apps.

Eyefinity is modular and thus allows users to rearrange the number of discrete images created in addition to their shape according to your liking. Guru3D users and gamers will no doubt find this setup to their liking. It will be interesting to learn just what kind of living room you have if you were to employ such a configuration. Please post your setups in our forums.

We expect this to be a great feature for all kinds of simulations, the flight-sim community must be going wild for sure alright!

HAWX probably is the best title to show off. Mind you that if you watch the videos, make sure that the HD button is enabled. Please read our full article on ATI Eyefinity right here.
