AMD Shows off Three new Sockets at Spring IDF 2006
 

The Turion 64 X2 will be using AMD’s new Socket-S1, the mobile version of Socket-AM2. The 754-pin mobile Socket-S1 has a dual channel DDR2 interface like the 940-pin desktop AM2 socket. You may be wondering how AMD was able to cram more than twice the data pins in a 754-pin package as they did with the original Socket-754 Athlon 64s, the answer is that the first generation of AMD’s Athlon 64 was a bit over-designed for its needs. We’ve heard that around 10% of the pins on the original Athlon 64s were unnecessary, so with some tweaking it’s not too far fetched to see a dual channel memory controller implemented in the same number of pins.

aha! explains why some CPU with broken pins just kept working perfectly

That is good to hear something that Intel could not get even close in its 90nm processor in thermal management.

I'm not realy happy with this.
I used to not like Intel because they changed their socket so often while AMD just kept it's socketA.

Now they are doing the same, S745, S939, S940, AM2, S1 and what's next ?

It's a complete difference, now it's intel who keeps using the same socket (tough, I now blame them for their chipset, new cpu means new chipset means new mobo, so you have the same 'problem').

Hope this isn't going to become a tradition :gay:

They both try to get into your wallet. The question is which one does it better in such a way that you will even say "thank you for taking my money, please come back soon".:)

multiple sockets are stupid :/

That depends on which side of the cash register you stand.

Indeed, it's all about the money, our money. And both have to keep mainboard manifacturers alive, don't they? They would all go down the drain, if we could keep a mainboard for 3 generations of cpu's.

Athlon Thunderbird - Athlon XP - Athlon Thoroughbred

Sempron S462.. close to 4 generations ;)

Not to forget all the Duron's and of course the Barton :D
