you know pci Xpress cards are they backwards compatible with pci cards in otherwords do pci cards work in the pci Xpress slot

will you see a difference wether you get and agp card or a pci Xpress card?

pci-express are 16x twice as fast as an AGP 8x there is alot of difference

true but there is no noticeable benefit from the additional bandwidth unless you do a lot of video editing which can make good use of the full duplex bandwidth

those x are different im pretty sure, 16*x and 8*x are not the same x so you are not multiplying by the same thing

Im almost positive AGP 8x is faster i heard it somewhere

not a computer buff but just lil, info

but i could be wrong

Man you have gotta start reading and doing research before you make posts.

The interface supports speeds that are roughly twice that of AGP8X sure ... but two factors kick in:

1. As Cromwell said, there is no benifit for gaming

2. Even for video editing, since video editing is primarily (and almost exclusively CPU/RAM bound having that funky interface wont matter

3. Cards arent capable of chucking data quite that fast .. now when you consider benchmarks and calcautions that say such-and-such card can transfer data at such and such GB/s ... thats all assuming 0cycle calcuation time (i.e., you're measuring the infrastructure speed) ... when you factor in the processing time and such for all the TL and geometry stuff ... it drops real fast

In some instances yes but those are really really unfair comparisions and such

Praetor are agp cards going to be whipped out because pciXpress has taken over

Was this answer helpful ? Yes No

robina_80

it'll take a while for PCI-X to completly take over from AGP. At LEAST 6 months-a year.

& this topic has been (slightly) covered before
