Could someone explain to me if a new PCI Express card can physically fit in to a AGP 3.0 slot? Because when I read the Intel paper, they said AGP 3.0 has max. out, and thus they choose a new tech., namely PCI express x 16, to move forward.

Now looking at this link

http://mirror.ati.com/products/fireglvseries/FireGL_family_r5B.pdf

the slot don't even look the same. But if they are not the same thing, then how can card like Ultra 6800 claim it supports AGP 3.0 and PCI Express?
 
It's probably some performance comparison thing or a misprint.

I thought the same thing when I was reading the specs on the cards on newegg.
 
first of the 6800 model does support agp or pcie, although you willl be buying one version or another. no pcie cards cant fit in agp slot nad on purpose if for no other reason then to keep people from puttign them in there. they very different protocals. most info on any new products is somewhat incorrect, just imagine your grandma copy and pasting the 6800 info from nvida webpage onto the newegg page she wont notice any discrepencies among cutting edge tech terms!

however ive got a smalll rant about the whole pcie thing:

the agp-pcie is turning out to be much like the ide-sata upgrade

of course no desktop hard drives were even close to maxing the "bandwith" neither were desktop graphics cards close to maxing 8x agp.

run some games at agp8x then switch it down to 4x and 2x in your bios and real quick youll see 1-3% performance decrease in almost all situations.

sata and pcie both have seriel techs, so they can send info both directions at the same time, and just as the sata are much cleaner involve much more flexible and thinner paths.

but youll see as much boost from a pcie as you will see from a sata hard drive.. that is not much any time soon. however mobo design flexiblity and getting rid of those fatass ide cables are nice perks, but their real magic in performance is sometime away.

my speculation: hopefully the seriel trace routes (meaning flexible trace lengths) wil be where in the case the graphics card moves too. cards will be large and heavy soon . revamp the upside down design with everything where its near impossible to get airflow, is quickly becoming a heavy inconvenience and limit to graphics progression

you know how anandtech has said that new nvidia cards are suppossed to run faster on nvidia mobos. i figure they probably did one of the following

-o/c the agp bus (we al know nvidia cards can handle fsb changes but ati cards are picky)
- tweak the latency on the agp bus
- enable a few extra trace paths
- or add something like a new level of dma for agp
 
PCI-X is NOT PCI-Express.
PCI-X are 64 bit PCI express slots made for servers
PCI Express is known as PCIe

and PCIe cards cannot fit into AGP slots, and the 6800 PCIe cards have a small bridge chip to make them work with PCIe.
ATI cards are native PCIe.
 
yea i know what pcix for servers is,, sorry if you were confused by my meaning for leaving out the hyphen.

Okay, I'm not picking on your nose, since we are talking about the correct terminalogy here, let me correct a minor thing:

PCI-X are 64 bit PCI "Extended" slots made for servers, which is really what that X stands for, Extension of the original 32 bit PCI.
 
The biggest advantage i see of PCIe right now is the chipsets that will allow 2x16X slots, for SLI, this will be my next setup along with 2 xeons and 2 of whatever is the best grapfix SLI card out.
 
Could someone translate the following to me:
Instead of being connected on the motherboard, each SLI card will be connected via a dedicated connector, which will connect to special slots on the card's PCB. Add-on card vendors described the card as a free-floating piece of logic connected by two connectors, one to each card.

So far, Nvidia has not informed its partners how the SLI connector will be sold, or its specifications. A concept demonstration of the technology on Nvidia's web site indicated that the graphics data would be fed out of a single vide connector, implying that the cards will have to talk amongst themselves via the connector. According to add-on card vendors, the second card is limited to an effective PCI Express rate of 8X, not the 16X bandwidth available to the primary card, meaning load balancing will have to be done. Load-balancing capability will be built into Nvidia's Detonator driver model, Nvidia said.

What are they saying?

But what if I don't know it? I only need 1 PCIe card connected to my future computer. Do I still have to buy the SLI bridge card?

As we all know, in the old days, we snap the video card on the motherboard and we are done. In short, it would be nice if there is a picture showing how the SLI works.

Scalable link interface is the generic name, MIO, HyperTransport, 3GIO, Infinity-band, and PCI-Express are TradeMark type names. "Scalable link" because they are scalable for even more connections and further increased bandwidth, for example Multi-Opterons can use one single HyperTransport link or more than just one. PCI-E have multiple channels for multiple usage assignments.

Here you go.
 
Well, I only buy brand name like Compaq, so I don't think they have a dual slot PCIe motherboard. As well, if the video card already come with 2 DVI port, I can already connect to 2 LCD. That's more than good enough for me. I am really using 1 LCD only.

if only that were true, sure it may be the future but agp 3.0 has not been maxed out yet

Nobody can max AGP 3.0 out if half the damn super-duper graphic hardware don't f*cking worked.

My R9700 PRO only works at AGP_4X and nothing else worked, and then you even get stupid fools pretending to be experts claiming "PCIe buffers" made ATI hardware "native".

They are too f*cking ignorant and stupid to know nVIDIA's bridge also used "PCIe buffers".
