Well look at what he just said:

its a 486 CPU that just has its internal clock quadrupled....

here is an example.. a 486dx2-66 is just a 486 33MHz CPU with its internal
clock DOUBLED, to make it 66MHz. The same idea as above.. the CPU above
is jsut a 486-33 class CPU with its internal clock QUADUPLED. 33 * 4 =
132. <they do a bit of funny math to work it up to 133 :>
