A sound card, HDMI compliant

R600 HAS A secret weapon, an internal sound card. This is the one thing
that Nvidia's G8x can't match, other than HDCP on dual-link HDMI.

The ATI sound implementation is not GPGPU code. It is dedicated silicon,
probably brought on by the Vista DRM infection and MS twisting arms to
force it on people.

In any case, R600 will be compliant with the Vista requirements and can
send sound directly over a HDCP/HDMI link. We are told this is a full HD
sound setup, not a cheesy 2.1 channel thing.

In contrast, NV G8x parts can't do this. They have to run an external
cable from the sound chip to the GPU. This may not sound like much but
it blows out several kinds of auto configuration and worse yet violates
Vista logo requirements
http://www.microsoft.com/whdc/winlog...uirements.mspx. One has to
wonder if this is why NV can't seem to make a functional Vista driver
six months in.

The problem with Vista is that the DRM infection mandates that you do
not share S/PDIF output over unencrypted links. R600 does this by
combining audio and video streams, then pumping them out over HDCP
infected links. This is user antagonistic DRM, but it complies with MS
logo requirements, and they don't care about user experiences any more
than the content mafiaa.

Add in that the R600 can do dual-link HDCP and you are going to be
swimming in bandwidth, more than enough to pipe sound down.

Nvidia's G8x on the other hand can't do dual link HDCP at all, so if you
have a 30-inch monitor, you will get a black screen. At that point,
sound is the least of your problems.

Basically it looks like the sound card in R600 is going to be the killer
app for home theatre type apps. G8x simply can not do what is needed
here, buggy drivers or not. While the DRM infection stinks, at least
R600 will be able to comply.
