[Solved] Just what is "Native" USB 3.0?

I've been reading up on Sandy Bridge vs Ivy Bridge forums and articles, and one term that keeps popping up is whether a chipset or CPU will have "Native USB 3.0 support". I've googled it but there isn't a clear-cut definition anywhere, just tons and tons of people reffering to it. Just what does it mean? I mean... if a motherboard has USB 3.0 ports, it's going to have to support it. Why does it matter if the CPU supports it or not? Do the different kinds of support give the USB3 different speeds?

current usb3 implementations use third party hardware on the mobo (which then may consume PCI-e lanes etc.), native means that its built in with no third party components. Should therefore be cheaper and may not require pci-e lanes etc.

No, you'll still have usb2 only ports.

Ivybridge chipsets for ex: z77 will have native pcie 3.0 support on it.

I'm not worried, I just want to understand what exactly it means. So current USB 3 data is passing through PCIe data lanes? Does that mean current USB3 are functioning at 50% of their theoretical max? Or 75%. Or 99.5%?

I would like more info then just "This will have USB 3 native support and this will not."

It's quite good enough, thank you.
