16x have 16 times the bandwidth from 1x...
it's the amount of "lanes",

keep in mind that PCIE Express V1.0 have basically half the bandwidth per lane compared to V2.0, 3.0 also offers a big jump from 2.0 per lane.

For once I think the wiki actually has a pretty good article that explains how it works.

16x is not available on anything but GPU's and cache accelerator cards for like 80% of all the people.

even dedicated IO controllers are on 8x
