     X6 1090T release moved forward, 1075T delayed

    After the Core i7 980X, then the GTX480, the next big hardware announcement we’re all waiting for is the Phenom II X6 Thuban. With clocks revised upwards on the early rumours and pricing expected (though not confirmed) to be attractive, this range of processors is much anticipated.

    With respect to the models available at launch, rumour has it that the 1035T and 1055T and more recently the 1090T will be the first models out. While the 1090T is reported to have been moved forward at the last minute, the release date of the 1075T seems to have been pushed back to the third quarter of 2010.


    The 1090T is the first model in the range with a clock of over 3 GHz without the turbo core, the 1055T having a base clock of 2.8 GHz. To access the symbolic limit of 3 GHz then, we’ll have to go top end of the range at first.

    Given that the 1090T has the same TDP as the 1075T, its Vcore is unlikely to be any higher. It remains to be seen if this is why the 1075T is running late… are there too few Thuban’s available above the 3 GHz barrier, in which case AMD is making do with the 1090T release at 3.2 GHz in low volumes for the time being… or has AMD chosen to sell more 1090Ts, for which it can make a larger margin?

    Lastly, one line in the slide above is rather interesting. It says that the Turbo Core on the Phenom II X6s is active when half or less of the cores are active. If the load is shared across 1, 2 or 3 cores then, the Turbo Core will be active, while the CPU will run at its nominal clock if 4, 5 or 6 cores are in use. It is regrettable that any clock increase won’t take place when more cores are in use, as is the case with Intel. The Intel turbo feature is however limited to just 133 MHz beyond 1 core (2 on the i7-980X), the TurboCore being faster with 2 and 3 active cores.



     AMD officially launches the Opteron 6000s

    While AMD’s consumer division is actively preparing the Phenom II X6s, the pro side is launching its Opteron 6000s, better known under the codename Magny-Cours.

    With 8 or 12 cores, they have the same architecture as the Opteron Istanbuls, but with their lot of innovations. Significant improvements have been made on the Magny-Cours, especially in terms of energy management, the memory controller and communication between different cores and processors.

    This last point is important in terms of AMD’s latest offering and they laboured the point at their press conference at CeBIT. Up until now, there was quite a price difference between the processors capable of functioning in pairs (2P platform) and those able to function in groups of 4 (4P platform). It’s a real coup for AMD to be able to announce that the 4P configurations will be sold at the same price as the 2Ps! This is important in the server world.

    The Opteron 6000s have a great price/performance ratio, the chips ranging from $266 to $1386. It remains to be seen how Intel will react, with its Nehalem-Exs to be announced tomorrow.
