CAT5 is not recognized anymore. CAT5e is pretty much CAT5 with a higher bandwidth. I've seen 5e with specs ranging from 250-650MHz, while the bandwidth of 5 was 100MHz. CAT6 has a bandwidth of 250MHz, but its other specs are also higher than those of CAT5.

Category 3 - loosely twisted pair - tested to 16 MHz (commonly used for phone wiring, also used for 10 Mbps ethernet)
Category 5 - tightly twisted pair - tested to 100-125 MHz (commonly used for 100 Mbps ethernet)
Category 5 Enhanced - similar to CAT 5, with more stringent specifications for Near End Crosstalk (NEXT)
Most CAT 5 would meet CAT 5e specifications if tested...
Category 6 - wire is a larger gauge - longitudinal separator between pairs - overall cable is thicker than CAT 5 - tested to 250 MHz (commonly used for 1000 Mbps ethernet)
Category 6 Augmented - more substantial separator between pairs - jacket is thicker to add space between adjacent cables - thicker still than CAT 6 - tested to 500 Mhz
Category 7 - doesn't officially exist yet...
