* Ken Maltby:
You seem incapable of reading my posts, and comprehending
what is being said. It might help if you read complete sentences
and paragraphs. Placing your own interpretation on my posts may
make you feel good, but is no help in the process of communication.
Again, a manufacture's use of a design that includes a RAMDAC
400Mhz or over shows that, the card was built to a high quality, in
the areas that relate to video editing. The RAMDAC's contribution
to that quality is more than you appear to allow, but it is only one
part of the design. My point, again, was that if a card has this area
of the design addressed, it need not include the more expensive 3D
acceleration features that are added to GPU and Video Card
designs (for gaming), to be an excellent card for Video Editing.
This makes it a good screening factor during the process of
selecting a video card for video editing, The subject of this
thread.
And all this is still utterly BS.
First, the RAMDAC bandwidth only limits the available resolutions and
refresh rates for the VGA port and the analoge part of the DVI-I port.
It says exactly *zero* about the signal quality. The parts that mainly
influence signal quality (which affects image quality) are the output
filters and that's it. The signal quality of a 300MHz RAMDAC is as good
as the signal quality of a 450MHz RAMDAC, period.
Second, as RAMDACs are integrated into the GPU for almost a decade now,
the bandwidth of the RAMDAC tells you *nothing* about "how well a card
was designer [for video editing]", period. A manufacturer orders a
certain type of GPU, there is no choice for RAMDAC bandwith. Low end
GPUs often come with 300MHz RAMDACs while midrange and highend GPUs come
with 400+MHz RAMDACs.
Third, as the majority of card makers use reference designs by ATI/AMD
and Nvidia the difference between gfx cards of different board makers
are usually limited to GPU/memory clock rate, cooling (different heat
sinks/fans), different analog otput filters, different memory modules,
different PCB colours, the goodies (i.e. games, adapters, software) that
come with the card and finally the price.
An inexpensive card can be lacking 3D gaming accelerations
but still be very good for Video Editing, if it is designed to the
quality that would include a 400Mhz or better RAMDAC.
And this also is just plain BS. Maybe you first should learn what a
RAMDAC does:

As to the subject (video editing): the RAMDACs have absolutely *nothing*
to do with video editing. RAMDACs are a part of the GPU to drive
analogue monitors and nothing more. All other functions (like overlay
planes which is used also by video applications) are part of the GPU
itself and have also *nothing* to do with the RAMDACs. Even worse, when
video editing is done with two digital monitors (which is usually the
case today) the RAMDACs do exactly *nothing*.
You appear not to have any interest in the subject of this thread,
and I have no plans to hijack the thread to get into a technical
debate to correct your misunderstandings of the issues involved.
I'm indeed very interested in the subject. And the reason for me
answering to this thread is not to attack you (I don't give a shit who
you are) but simply because you try to sell your bullshit here. This
group is here for helping each other, and spreading your nonsense
doesn't help the original poster one bit. The BS is of the same quality
as what DaveW usually spreads around, the only difference is that your
posts are longer.
Now hack away at my sentences and paragraphs, I'm done with
you.
Yeah, whatever. Please get at least some basic knowledge before
answering any questions. Telling stories when you don't know shit
doesn't help anyone.
