Folling an announcement from ASRock a couple weeks back which unveiled the world's first PCI-E 3.0 equipped motherboard in the form of the Fatal1ty Z68 Professional, ASRock has now provided us with some details of their entire new "Gen3" lineup sporting next-gen PCI-E 3.0 architecture.
As you can see, PCI-E 3.0 provides up to double the amount of bandwidth possible from the current 2.0/.1 standard, with a raw bit rate of 8.0GT/s.
As you can see above, ASRock is kicking out five Gen3 Series boards and below is a chart with a detailed rundown of the feature sets on offer between the boards :-
It should be mentioned that once these boards are readily available, the PCI-E 3.0 slots will only operate at PCI-E 2.0 speeds when using current Sandy Bridge CPUs. One of Intel's upcoming Ivy Bridge CPUs which have PCI-E 3.0 support is needed for the slots to run in their native PCI-E 3.0 mode.
