PCIe 2.0 Ratified

Yesterday the PCI Express Special Interest Group, also known as PCI-SIG, announced that it finalized the PCI Express 2.0 specifications. The specifications initially entered the release candidate stage a little over three months ago.

The new PCI Express 2.0 Bus Specification doubles the interconnect bit rate from 2.5 GBps to 5 GBps. PCI-SIG describes this bandwidth hike as “by far the most important feature of the PCI Express 2.0 specifications.” Doubling the interconnect bit rate increases the aggregate bandwidth of a single PCI Express x16 slot to 16 GBps.

Looks like this is a good excuse for me to hold out longer on Conroe :p:

The 16x of PCI-E isnt even used yet (bandwidth) so there really isnt any point to have this yet.

I was thinking that!

AGP was around for ages I swear.. But yet PCI_Epress has been out 2-3 years and they want to upgrade..

Stuff that is what I say! :(
 
If you read the article you'd realize it doesn't only enhance bandwidth, but it also helps with latency issues, brings more lanes to chipsets for better SLi/Crossfire speed, etc.
 
Yea more bandwidth you dont really need yet. Its almost pointless to upgrade already when AGP wasnt even fully utilized.

So you're against innovation in the technology field?

AGP's bandwidth limit has easily been exceeded now
 
I believe AGP was exceeded when the Geforce 7s came out.. ;)

I don't like the idea of wasteing PCI-Epress so soon! AGP was out for more than 2-3 years.. :(
 
Yea at least it has that. I didnt see much of a difference between AGP and PCI-E and i had a Geforce7 series card on AGP (7800GS). And i do like the newer technology and everything but i dont see the need for it yet when the cards dont utilize it yet.
 
well you can't run 8800GTS/GTX in SLI with 8x 8x slots as there's not enough bandwidth for the data to run through, so some more may well be needed by Q3/4

I thought they already had boards running 16/16? At least thats what that Asus baord is led to believe.

Yes they do indeed, but you can't run 8800 SLI on 8x8x, I was just saying you actually need 16x16x

It's backwards compatible too, so it's far from the transformation like AGP -> PCI-E.

Thats better.. Will the PCI-Epress chips use all the bandwidth on PCI-Epress 2?

Because that would rule.. ;)
 
perhaps 8800's could run 8x 8x with the new 2.0 pci-e slots. will be nice to find out when motherboard manufacturers are gonna phase these in, as i'm guessing its gonna be a bit on the expensive side to manufacture atm, cuz of loyalties etc
