AMD Phenom II X4 T Series Detailed
In a few weeks' time, AMD will be releasing its brand new set of six-core Phenom II X6 processors. These processors are based on the "Thuban" core, which is a socket AM3 implementation of the Istanbul six-core architecture. Along with as many as four Phenom II X6 models including a high-end Black Edition part, AMD will be introducing new quad-core processors under the Phenom II X4 T series. Some of the first two models in this series includes the Phenom II X4 960T and Phenom II X4 940T.
The Phenom II X4 960T operates at 3.30 GHz, while the 940T runs at 3.00 GHz. What makes these chips different from existing chips based on the Deneb die is that it is in fact based on the Thuban die with two cores disabled. The resulting quad-core chip is codenamed Zosma. The other characteristic feature about not only Zosma, but also Thuban in general, is the introduction of a feature called "Turbo Core". The feature senses performance needs and steps up clock speeds of some cores, while powering down others. The stepping up of clock speed happens on the fly, and using a jump in BClk multiplier by a few units. The new chips also come with the unofficial incentive of being able to unlock the two disabled cores to turn it into a six-core chip. Unlocking may not work in all cases.

is there a new instruction set?
no 32nm AMD this year?
AMD should've done better than that to keep with Intel.
everytime Intel launches a new generation of cpu, it thrown a new instruction set, which in turns, makes processor execute apps faster.
btw, this is an info about thuban pricing:
Phenom II X6 Six Core
1090T Black Edition: 125(W), AM3 Socket, 9MB Cache, 3.2 GHz Freq @ 295 USD
1055T: 125(W), AM3 Socket, 9MB Cache, 2.8 GHz Freq @ 199 USD

and yes...no AM2+ support. it's dead already. no future support for 'em. but as always..you can put AM3 processors on an AM2+ mobo.not sure with thuban though
Eg: Hypertransport >>>> QPI
On die memory controller >>>>> Intel same
Intel's turbo >>>>>> AMD's turbo
True quad core arquitecture (amd) >>>>>> True quad core arquitecture (Intel i7 and later)
what will be in the next few years? Intel's fusion? :shadedshu
