The GPU techies designed chips with both HDMI and DisplayPort standards in mind. and everything is embedded inside the GPU, instead of using external cables. The R600 architecture will use the PCI Express x16 connection to the fullest, as the chip will not work only with video data, it will also be able to receive digital audio for embedding the video and audio signal in one.
Why? You might ask, and the answer is simple: to deliver both video and audio content using HDMI.
R600 boards will be shipped with at least one DVI-to-HDMI dongle, with DVI serving as the bandwidth provider for video and audio. Best of all, we learned that the R600 chip has the bandwidth to drive not one, but two HDMI ports at the same time. This should not come as surprise, since resolution-wise, you're talking about either driving two displays in 1920x1080 (1080p) or 2560x1440 (1440p) - and the R600 has enough bandwidth to drive both video and sound - at least, the most powerful versions will have enough juice.
Whther we are talking about single or dual-HDMI design, the R600 or Radeon X2800 and its mainstream (RV630 aka X2600) and low-cost variants (RV610 aka X2300) will be known to the world as first consumer GPU chips that are able to blend video and audio together and output it using single cable and having DVI as a transition port. µ
This is a smart move. µ
