[simpits-tech] Monitor question

There is a premium - the AGP is faster - 2GB with AGP x8 as opposed to PCI
with 133MHz , and it has it's own bus - it's not on the PCI bus,
read this article for the exact difference
http://www.tomshardware.com/mainboard/20000214/index.html
But ( big one ) for the high end cards, the memory throughput is not even
close to what the GPU needs so you can only rely on the internal memory,
in the low end cards you will see an improvement.
read the conclusion here :

if you read the entire article do note that the 440 new version has a
higher clock not just AGP x8.

HI, Ido.

well, you've got me spinning. if there is next-to-no difference between AGP
and regular PCI, then why do motherboard manufacturers bother to make the
slot? why do graphics card manufacturers bother to implement it? is there
more than just the memory bandwith considerations with the connector to
make it useful? is it because the AGP standard is so poor that PCI is
outpacing it??
and why doesn't every graphics card manufacturer just skip supporting the
slot since there is only one (AGP slot per motherboad) to begin with?

if you are correct, it all seems like a big waste of time, and that
everything everyone has told me about AGP is false. there _has_ to be a
premium with use of the connector _somewhere_, or (again) it all seems like
a waste of time.

if someone else can help clarify this, the help would be greatly
appreciated.

      Actually if you look at this -
      http://www6.tomshardware.com/graphic/20020718/radeon9700-04.html you
      will
      see that there is no difference for 3D also in AGP Vs PCI - there
      memory
      throughput of the card is 19.4GB per second and what the AGP bus
      gives you
      is 2GB per second , so it will never improve the cards performance
      unless
      you use huge textures which doesn't happen in todays games and when
      it does
      we'll get the 256MB of the 9700 or the new nVidia card.

      The problem is that i didn't see any high end graphics cards for PCI
      yet -
      the best I've seen is the GeForce 2 MX, if there was a radeon 9700
      for PCI
      then there wouldn't be much difference from the AGP one.
