Friendz,

I have started a new topic Difference between PCI Express x16 and PCI Express 2.0

Add on your views about the same.

It's not really related ...
A port PCI-E x16 is wired (or powered, if we want to popularize a bit) in x16, meaning it will provide maximum bandwidth that the standard can offer. The standard PCI-E 2.0 provides just two times more bandwidth than the standard 1.0

is a change in standard
but the PCi Express 16 is either 1 or 2
16 PCI Express 2.0 bandwidth a bit faster

You just put a graphics card PCI E 16 2.0 on a motherboard pcie 16 1.0 without problem

you to find a PCI Express graphics 16x in 2.0
PCI Express graphics 16x in 1.0
and frankly its not much has changed me you ais SLI configuration and even ....
you can connected a pci-e x16 on a port in football 16x in 2.0 and 1.0

bandwidth is not "quick" as you say: p bandwidth is wide.

PCI Express architecture is based on "lines".
it affects about 1, 2, 4, 8 or 16 lines in general, a port PCI Express, and it is called PCI Express 1X, etc..
dans la norme initianle, le pci express 1.X, on a 250 Mo/s de débit par ligne PCI Express 1.X, on a 250 Mb / s throughput per line affected.
PCI Express 2.0, on a 500 Mb / s throughput per line.
there you find the speed of each port

yes and to keep it simple for the person who does not know too the port 16X PCI 2.0 allows a flow of information more quickly

The main difference between a pci-e 1.1 and pci-e 2.0 is the bandwidth. Pci-e 2.0 is completely backwards compatible with earlier cards.

It depends on the card, but i think every pci-e 2.0 card out right now is backwards compatible. No video cards even use all the bandwidth of an x16 slot, pci-e 2.0 isn't necessary.
