PCI vs. AGP 8x? |
|
|
I want to buy a 256mb card, can anybody tell me if there is a
difference in performance between a PCI and AGP 8x card if they have
the same specs? |

Do you mean PCI or PCIe? PCI express is another generation beyond the
old PCI, with many times the performance. Each of these requires its
own dedicated motherboard, so it's not just a case of getting a card.
Assuming PCIe, it looks like the best are about as good as the best AGP
8x (we're talking ballpark here). Personally I went with PCIe because I
look upon it as the future, whereas AGP is the past.

If you meant PCI Express (PCIe), then no, not really. If you meant PCI,
then yes, there will be a difference, because there aren't any fast cards
available for the old PCI slot available. The old PCI bus has a much
smaller bandwidth than AGP.
PCIe is not the same as PCI, and I don't think there are any motherboards
that have both a PCIe x16 slot and an AGP one. So, you don't really have a
choice in what style of card to buy.

Asrock makes several of them. ECS had some for a while, but they seem to be
discontinued.

Isn't the current PCIe (x16) a bit faster than the fastest AGP (x8)?
But yeah, either way, it is the future, and if I were to buy a motherboard
today, I'd definitely buy one that has PCIe for video.

In theory AGP 8x can in theory transfer about 2 billion bytes/sec
unidirectionally. PCI Express x16 can transfer 4 billion unidirectionally,
but it's a full duplex bus so it can transfer a total of 8 billion with
symmetric traffic.
All irrelevant with video boards though--so far nobody has demonstrated that
AGP4x is a bottleneck.

If I was buying a new motherboard today I'd definitely go with PCIe.
However, the OP only asked about buying a videocard. :D

I have a BioStar NF4UL-A9 mainboard that has PCI-E, and an
"IGP" port that allows you to run an AGP video card instead of PCI-E.
Although not every AGP card will work. However, alot more do than what
Biostar list as being tested. |

One thing with these boards is that they usually connect the AGP port to
the PCI bus which makes any AGP card really slow. Nothing someone
really wants to have....

Asrock connects it to the PCI Express bus. While there's a performance
penalty in some cases, it's not down to PCI speed.

Don't know for this Asrock board (but I'd be really surprised if Asrock
does it different than others), but on PCIe boards with AGP the AGP is
just a PCI device which is connected to a single lane on the PCIe chipset.

Quite a trick connecting a PCI device to a single PCI Express lane. But
Asrock's Web site describes their product in some detail--why don't you
read about it and see what they say?
