what is the difference between AMD K62 and K6III and the "+" Cpus ?? From what I can see the K6III+ is a 100Mhz bus. I would Imagine that an Overclocked k6@ would outperform the K6-3 ??

/EDIT
Everything I needed to know.

Basically the K6-IIIs just had another level of cache. I think they all ran at 100Mhz bus. None of them overclocked well. I'm not sure what the +s did, but I think it was something to do with the mobile chips and voltages.

I don't remeber all, but I guess they are like:

K6-2: 3Dnow!, 100 MHz FSB, off-die L2 cache, 0.25 um.
K6-3: 3Dnow!, 100 MHz FSB, ON-die 256 KB L2 cache, 0.25 um.
K6-2+: 3Dnow!, 100 MHz FSB, ON-die 128 KB L2 cache, 0.18 um (reduced voltage)
K6-3+: 3Dnow!, 100 MHz FSB, ON-die 256 KB L2 cache, 0.18 um (reduced voltage)

A K6-III,or 2+, or III+ will generally smoke a K6-2 that is 100 MHz faster. The extra cache makes a HUGE difference. The K6-2+ and III+ overclock much better than the 2's and III's did. Most people who had 2+ 450's were able to get them to around 600MHz.
