I'm well aware of Timmy's background and that he
doesnt need that level of comment aimed at a newbie.
So you thought the oneliner without any explanation was enough?
It is clear from his next reply that it wasn't.
But we'll probably never agree on that.
(Sometimes I really wonder if your aim is to help people, or if your
goal is to confuse them)
Pity you mangled the story considerably.
Pity you cannot point out where it is mangled, so we can have a normal
discussion about it.
There's more than just that. Plenty of systems dont have full
32bit PCI.
What do you consider "not full 32bit pci", if it is not connected to
the slow pci implementations like the one I mentioned from via?
Particularly the sort of older system that you're
likely to want to use one of those PCI cards in because the
motherboard bios doesnt have large drive support.
You're overstating that too, just like you did with the 133MB
PCI thruput claim. That isnt in fact that commonly seen at all.
I am not overstating anything. I have already made it perfectly clear
that it isn't commonly seen at all. I don't understand how you got the
impression that I would claim anything else.
I have just given an example of how to create one of those rare
situations.
I dont, particularly with the older systems where an
addon card is likely to be used because the motherboard
bios has a problem with large drives, and those where
the PCI is used for more than just high thruput to hard
drives, particularly with analog video capture etc.
How much pci bandwith do you guess is used during analog videocapture?
My experience is with DV which is only 6MB/s, but lets take a high
load for analog: 720*480 at 24bit color at 30 fps. That is 31MB/s
Let's be generous and add 1MB/s for sound.
Then we also need a modern IDE harddisk that can write that fast.
the harddisk is waiting for data from the capture card, so it's
limited to that and can't make use fo the burst speed to the cache.
so suppose we have 32MB/s going over the PCI bus for the capture card.
(actually I don't think that it will do that for capturing)
Then we have again 32MB/s for writing it to the harddisk.
So that makes 64MB/s Even counting the overhead and poor
implementation of the pci bus we are well clear of the maximum for
32/33Mhz pci.
Now we have sound, video and harddisk using pci. I can't think of much
else that will be used at the same time for videoediting that we can
add on top of this that will overload the pci bus.
But I'm open to suggestions.
