AMD Radeon HD 6870 GPU Features

The AMD Radeon HD 6870 GPU contained in the MSI R6870 card has all of the major technologies that the Radeon 5xxx cards have had since last September. AMD has added several new features, however. The most important ones are: the new Morphological Anti-aliasing, the two DisplayPort 1.2 connections that support four monitors between them, 3rd generation UVD video acceleration, and AMD HD3D technology. In case you are just starting your research for a new graphics card, here is the complete list of GPU features, as supplied by AMD:

Additional hardware (e.g. Blu-ray drive, HD or 10-bit monitor, TV tuner) and/or software (e.g. multimedia applications) are required for the full enablement of some features. 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.

  1. AMD Eyefinity technology works with games that support non-standard aspect ratios, which is required for panning across multiple displays. To enable more than two displays, additional panels with native DisplayPortTM connectors, and/or DisplayPortTM compliant active adapters to convert your monitor's native input to your cards DisplayPortTM or Mini-DisplayPortTM connector(s), are required. SLS ("Single Large Surface") functionality requires an identical display resolution on all configured displays.
  2. AMD EyeSpeed is a set of technologies designed to improve video quality and enhance application performance. Full enablement of some features requires support for AMD Accelerated Parallel Processing (APP) technology and/or AMD's Universal Video Decoder (UVD).
  3. AMD PowerPlayTM and AMD Accelerated Parallel Processing (APP) are technology platforms that include a broad set of capabilities offered by certain AMD RadeonTM HD GPUs. Not all products have all features and full enablement of some capabilities and may require complementary products.
  4. Requires application support for AMD Accelerated Parallel Processing (APP) technology. AMD Accelerated Parallel Processing technology works with applications designed to take advantage of its GPU acceleration capabilities.
  5. AMD HD3D is a technology designed to enable stereoscopic 3D support in games, movies and/or photos. Requires 3D stereo drivers, glasses, and display.
  6. AMD CrossFireXTM technology requires an AMD CrossFireX Ready motherboard, an AMD CrossFireXTM Bridge Interconnect (for each additional graphics card) and may require a specialized power supply.

Good review. My time for buying parts and building my next system is fast approaching and it will probably have to do me, for a long time. Reviews are what help us to make smarter decisions when we spend our money. While the cost of two GTX460's is not resoundingly expensive for most, it represents a lot for me. (I'm on a disabled Pension) I didn't want to buy the 1GB GTX460 pair of cards without knowing more about the latest ATI offerings. With your help I feel that I can make a final decision now and not blow it. I appreciate it too.

Great Review! Thanks so much. I'v been doing some research for my next big build and I really needed to find a graphics card that fit my needs and this is wonderful especially considering the price. Although I do wish it had more for the voltage controls.
Now I just have to decide whether to go with this or wait until the Caymans come out. They just got pushed back again tho... from end of November to mid December. =/

Once again, Great review!!! Really in depth and exactly what I was looking for.
