PCI-Express 3.0

[kukimuki1]

Hey guys new to the Forum !

My question would be about the "socket" where we put the card. I recently read in the news section that the new HD 7000 series GPU's will primarely be built to support and take advantage of PCI-E 3.0 but will still support the 2.0 umm "sockets" with little throttle when using the most High End ones . So...

Intel's Z79 or something chipset will support 3.0 but cant find any evidence that AMDs brand new FX9xx/x9xx chipsets support 3.0 .

I would like to know if this depends on the chipset or just the motherboard making company to implement it and wil there be an AMD motherboard supporting pci e 3.0 anytime soon ?

Why is this so important to me ? I am planning after 4 years to buy a new computer and waiting for the AMD Zambezi Processors because i hope they will be cheaper then Intel . But would also like to buy a next gen videocard next year from Nvidia . The Kepler yes. It will most probably come with 3.0 support even though no one wrote about it.. because why not ?

By the time Kepler is actually released, there will most likely be PCI-3.0 boards on the market. It's a bit too early to know as there is no information to confirm it.

Consumer cards barely saturate PCI-e 2.0 x16. There is no need for consumers to have PCI-e 3.0 x16 and indeed it will be backwards compatible.

I understand that but because of my old rig getting really outdated and cranky the only + thing is the GTS 250 that barely runs hardcore games :/ I just wanted to know if anyone knows if there will be AMD motherboards supporting it sometime this year Waited long enough to say thats it ill buy a computer when zambezi arrives but with a board that supports pci e 3.0 for the next year upgrade

Ooooo really ? Is there any tests or some profe . I mean i suggest that you know much better than me i am just interested

PCIe 16x 2.0 slots (we usually call them slots as opposed to sockets though the terms are mostly interchangeable) have 8GB/s of bandwidth which is really only even close to saturated by an HD 6990 (~$700) and you'll need a decent CPU to keep up. So unless your upgrade budget is best described as "astronomical" then it's probably not important.

Also I agree with erocker.

I am planning on a medium performance card sooo along the generation line like this GTX 460 - GTX 560 - aand would plan to buy aa umm GTX 660 So i guess it would pointless then to get a PCI e 3.0 board

 

[lilhasselhoffer]

Having the latest and greatest might be a bit of a foolish pursuit.

Consumer level graphics cards almost never saturate the current 2.0 level slots. This is evidenced by only slight performance drops when going from a x16 to x8 lane slot (check out tomshardware for the article).

If you think that you'll be crunching, and your budget is astronomical, then it might be worth is to wait for 3.0. If you're a human being with a reasonable budget, 3.0 is a joke without a punch-line.

If I were in you shoes, I'd wait for bulldozer and get the most reasonable setup (if you're bent on staying AMD). Waiting for 3.0 will take way too long, and be an expensive proposition, at the onset.

Ouuu i seee Hmm thankyou for the link and for the informations I'll just buy a normal AM3+ board when zambezi comes out

I would love to see a 6990 PCI Scaling test
