    Which version of Windows Vista support dual core cpu? Is there any
    which support quad core cpu?

  2. All versions of Vista support a dual core processor. Same for quad core.
    Home Basic and Home Premium only support a single processor socket, but that
    can be a single multi-core processor in that socket. Business, Enterprise
    and Ultimate support two processor sockets, again that could be a multi-core
    processor in each socket.

    My 2 cents,

    In summary, cores in CPUs is designed to be independent to OS, and it's just
    how much the applications (including OS) can take advantages of its
    processing power.

    Sorry, I replied to wrong person.

  5. Another interpretation is that the each cpu is a physical processor and each
    core is a logical processor. You can see the logical processors on the
    Performance Tab in Task Manager. There will be a CPU Usage History graph
    for each logical processor.

    Home editions can be installed on boards with one physical processor.
    Business editions can be installed on boards with one or two physical
    processors. Boards with more physical processors require one of the Server
    editions.

    Hyperthreading doubles the number of logical processors so an Intel P4 with
    hyperthreading enabled appears exactly the same as an Intel Core Duo, Core 2
    Duo, or AMD64 x2 on the Performance Tab.

    All editions of XP, Vista, and Server work the same in this regard.

    Hi,

    Thanks and exactly as you mentioned, but here is one thing that I don't
    know:
    Is above bound to license or is by design of the software?

    I don't know much about the architectures of Vista, XP, or even Win3.1 for
    that matter :)

    Its the design of the software.

    By the way, I shall rephrase the question so it may be more clear:

    By design means, it can't be installed and used on a board with two physical
    CPUs, whilst, it can be installed and used except it violates the license.

  9. It is limited by both software AND the license.
    So even if the product was not limited you would still be in breach of
    the license.

    So will it not install? Or install and just not use the extra processors?

  11. No it can be installed on a board with many (Physical CPU packages)
    processors but only one will be used.
    The software will remain operational.

  12. It will install and only use one on board processor package
    (irrespective of number of Cores).

    OK. Thanks for the clarification.

  14. Won't run.

    What Mike said.

    It's an "artificial" software restriction to support a licence condition.
    Effectively a bit of code somewhere says "If operating system edition = home
    edition of some kind, only support one CPU socket".

    Thanks for your reply.
    Let me ask a follow-up question:
    My present PC uses a mobo with two single core proccessors and with one
    set of RAM. Is it true that I can get same level of performance as that
    with the above by one dual-core proccessor with one set of RAM? My logic
    is that the OS does not care whether the two CPUs are on the same die or
    not.

  20. In the broadest possible sense , you will nerve get as good
    performance with a CPU with 2 cores as you would with 2 single core
    CPUs due to many physical constraints on the throughput and the
    underlying architecture of multi core chips. But this is a sweeping
    generalisation.
    The issue is not about the OS but about the data paths and mother
    board performance and many other hardware factors that can influence
    performance.
    But at a basic/simplistic level 2 real CPUs will perform better then 2
    CPUs on the same die sharing components and having to "cooperate" to a
    certain degree

    (and now we open a huge can of worms and comment :) )
