    Yup. Have since they started disabling SMP on Athlon XPs and forcing you to buy their then MP, now Opteron line. Same damn processor.

    You showed the middle finger to Intel. That says more than just "they could have performed better", it says you wanted a feature but it's not there on your specific processor. It doesn't make sense to show the finger for the lack of a feature you don't need anyway.

    Next time you should articulate yourself better, then you won't need to be "sorry".

    We don't need most of instructions in current CPUs. Basically all software can be run using only i486/i586 instruction set. But you don't want that as this makes software slower.

    Intel uses the exact same silicon for both SKUs, one has some of the silicon just disabled/burned off. It's a concious decision to sell basically exact same hardware at different price points.

    Yeah. So why show the middle finger if you know that beforehand and can make purchasing decisions based on it? I would only resort to the finger if I thought I got screwed over in some way. There's no screwing over in this case.

    @willmore
    Gusar is right, you have bought that processor knowing its limits, why are you angry now? It would make sense if you bought a processor with that feature and it didn't work, but this isn't the case..

    p.s. if you notice almost every producer sells crippled versions of its products to differentiate price ranges.

    Yes, HD6950 vs HD6970.

    Previously Black series vs normal phenoms.
    There are two methods to produce segmentation:

    - produce one full featured design and cut the parts out. Top-down.
    pros:
    1) can mix damaged chips
    2) easier to support by means of drivers etc, due to same "housing"
    3) cheaper to make, because they are made en masse and cut down as needed
    4) many other needed parts match all crippled models
    5) as effect, longer support cycle because cheap to maintain
    cons:
    1) no one likes crippling
    2) more raw material waste
    3) more energy loss

    - produce many designs, designed for each specific case. Bottom-up.
    pros:
    1) can pack more chips on single waffle, less raw material waste
    2) more energy efficient
    cons:
    1) they actually have nothing to de-cripple. They are crippled from design
    2) harder to maintain, smaller support window. For example, compare G92 based nvidia 8800-gtx295 vs HD2xxx-4xxx.
    3) harder to test, more bugs
    4) development costs more, more wastes due to incorrect overproduction

    * do not perform any segmentation, only filter chips based on their readings and clocks.
    Thats what I prefer.

    But I don't think this should interest you.
    You just pick good price and all features you need and you are done. Let manufacturers decide how they implement it - crippled after or crippled on paper, in the end it plays little role.

    That was an excellent troll you posted

    Good luck finding a compiler that will output any AES-NI instruction if you don't use intrinsics or assembly language inline.

    You know, one of the funding principles of RISC was that compilers can't use too complex instructions.
