difference between AGP 2x, and AGP 1x

[ThePsmear]

What is the difference between AGP 2x and AGP 1x, will an AGP 2x video card fit into a standard AGP slot. are there two kinds of AGP slots?? or just one main one.

agpx1 runs at 66mhz agpx2 runs at 133mhz cards are compatable with both i:e you can use an agpx1 in a x2 and vice versa but it wont make a agpx1 card run at x2 you can also change the amount of sys mem used for textures in some bios's
