from the article (1st post): Question: How do laptops with AMD or Intel chips that include integrated support for USB 3.0 differ from laptop's today that already have USB 3.0 ports (usually only one or two) that presumably are not integrally supported by their processor chips or only offer non-integrated chip set support for them? For example, here's a laptop with Intel Core i7 that has 2 USB 3.0 ports (first example I found after a quick search on newegg).
They use an USB 3.0 card with a NEC chip. Similar cards can also be installed in desktops, using a PCIe port. In this computer I have installed an EVGA $20 card.
