Performance gain from pcie 1.0 to 2.0

[ExtremeAlien]

If I took a pcie 2.0 card and stuck it in a 1.0 slot how much performance is lost? And how much is gain going to 2.0.

 

[Joe2005]

Exactly 21.4789% increase in performance from going to 2.0.

 

[ExtremeAlien]

So its very noticeable? Would it still be worth to buy a 2.0 for a 1.0? I just got this motherboard for Christmas.

 

[Joe2005]

I was joking.

Let's look at it this way, I have a 3850 which uses PCIe 2.0 technology. The 8800ultra uses PCIe 1.1 technology, will my card beat the 8800ultra?

It all depends on the card, and as of now no card uses up all the bandwith PCIe 1.1 has to offer so there really isn't that much of a performance gain, go ahead and get your graphics card.

not necessary for now.but if possible get yourself a board with pci-e2.0 port for future card.

PCIe 2.0 is suppose to give more performance, but all graphics cards on the market today will see little benefit from it

I'm planning to get the 9800gx2, Isn't it supposed to be pcie 2.0 and use all of it up?

 

[evil-xxx]

It's hard to say coz there are no tests even.

 

[Joe2005]

Wait 6 months till after that card comes out and buy yourself a whole damn computer, you'll be happier trust me.

The 3870x2, Two GPU's in one, doesn't even benefit from the increased bandwidth of 2.0. I'm going to be bold here and say the 9800gx2 will see no benefit as well.

 

[oscaryu1]

PCI-E 2.0 isn't even fully used yet. It's made for the future. Most likely the GeForce 9's won't be able to fully benefit from it.

And to think they're already starting on 64-lane PCI-e 3.0..
