Super socket 7 is not a different socket afaik.
yeah, honestly socket 5-7 have really similar and overlapping small changes
Most notable:
-The addition of dual plane voltage. This started in socket 7 but not all of them got it. by ss7 all of them had it.
-The addition of the various BF pins. there are 4 BF pins BF0 BF1, BF2, and Intel BF2 each with their own pin. the Intel BF2 was kinda forgot to history. Some motherboards got it but the only cpu to ever use it was the tillamook. which didn't work in most motherboards. instead, History marched forward with the AMD/Cyrix BF2 pin and Cyrix even went so far as to use the intel BF2 pin for another function.
-And then of course there is the fsb difference the SS7 was designed to run up to 100mhz stock
-Between socket 5 and 7 the added a key pin
-at some point the processors started using a inner row of pins also I am trying to recall which cpus had it though, I know the last cyrix MII 2.2v chips had them but not the 2.9v
-One nice thing though, while forwards compatibility was rife with issues(hence the various tweakers, see my signature), backwards compatibility was very good. you can run about any socket 5 or 7 cpu you want in a ss7
btw, just to get the word out there I'll include this: cyrix media gx and amd geode use a socket that physically is socket 7 but is absolutely not socket 7 electrically and those chips should never be installed in a regular motherboard or vice versa.
