Whats the difference between these chips? I'll outline what I already know:

The Phenom ii x6 chips have 6 cores instead of 4. (I know, I'm sharp ;)  )
The 1090T BE has the multiplier unlocked, where as the 1055T does not (however the FSB is still unlocked on the 1055T)
The hex core chips come with turbo core

Is that all? if so, why do I see people reporting higher OCs with the six core chips than the four cores? They have the same EVERYTHING except for two more cores, which would mean more heat so... I don't know. I'm lost on this, I know there must be something I'm missing.

The 955 is a Deneb core, as are all the phenom2 x4 cores afaik.
The X6's are a Thuban core, which is a pretty different architecture.

I thought Deneb and Thuban were just the "names". Aren't they both K10?

WEll FOR 50BUCKS MORE U CAN GET A 1090 INSTEAD OF A 955 SO ID SAY 1090 IS MUCH BETTER IN PERFORMANCE AND YOUR WALLET

Thuban is from the Istanbul (opteron) core, they are nearly identical as I understandit; while deneb is just a optimization of the original phenom core.

Phenom II X6 is technically on a different manufacturing process than Phenom II X4.
"AMD has included a Low-K Di-electric material in the design, which improves leakage while not significantly affecting transistor switching performance. This has allowed AMD to lower the TDP of this part as compared to what it could have been if the design had been left unchanged from Shanghai as well as using the older iteration of the 45 nm process"

My quote is from the first page, if you read it you'll find it.
