Mainly there are three types of AA. namely, MSAA, FXAA, and SMAA. They all do the same thing but with some differences.

1)FXAA (Fast Approximate Anti Aliasing): Its the least demanding form of AA, and smooths out edges with a minimal performance hit but it also blurs out textures. Makes them look a little muddy ya know.

2)MSAA (Multi Sample Anti Aliasing): The most common form of AA around, it does the smoothing out job well enough, and gives a moderate hit in performance. It doesn't affect the textures.

3)SMAA (Sub Morphographic AA) : Most demanding AA around. Gives a big performance hit but does the smoothing out job much better than MSAA. In some games this doesn't give as big a performance hit as it does in others.

As for the x2, x4, x8 stuff. Thats the number of times the AA filter is applied. For example, x2 means that the AA filter is applied twice, x4 means 4 times and so on. The more filters, the smoother the overall look of the frame on screen.
