    What operating system do you use?

    Does Windows Vista support Dual Core Processor or Dual Processor ? And is Windows XP working on update patch so Dual Core Processor or Dual Processor work with Windows XP :eek:

    And do you still have to slave the other Processor for some of work or how will it work?:confused:

    First, half of this is in the wrong place. Please post questions about Windows XP in the Windows XP section, and this is not the right place to post that poll (and I don't think anyone is using DOS or Windows 3.0 :rolleyes:).

    Anyway, Vista should "support" a dual-core, and so does XP so that question doesn't really make any sense to me...

    For your 3rd question, I'm pretty sure you just install Vista and it just works, like a regular proccessor.

    I'm not an expert in this field, so correct me if I'm wrong, but I'm sure that you just install it and that's all..

    I use XP -

    Yes

    It already does

    You don't "slave" a secondary processor. A second processor allows you to set certain processes "affinity" in the task manager. E.G. you run 12 tasks and 1 task is CPU hungry. You set all 11 tasks to run on CPU 0 and the CPU hungry 12th task you set the affinity to the CPU 1.

    VERY few home brewed/or developed applications take a second processor and use both processors in unison this is something called a multithreaded application. If its multithreaded it will do what your inquring about.

    So If I'm runing a virus scan and doing video editing I can set CPU 1 to do the video editing and CPU 2 to do the virus scan ?


    What about Dual Core Processor how will it work?


    Are you saying the applications do not support Dual Core Processor or Dual Processor :eek:


    What is Hyper-Threading :eek:

    My suggestion is you could have considered making it multiple choice, seeing many of us use multiple OS's! ;)

    You're right. I have W2KPro on 2 machines, XP on 1, 98SE on 1 and ME on 1, plus I use a few different Linux Live distros.

    Hyper-threading:

    All programs will "support" a dual-core (i.e. your computer isn't going to crash or anything), but some rare applications have the ability to use both processors, like some of Adobe's high-end products. But even if you run 10 programs that don't use multi-threading, a dual-core will still help you, because you can assign 5 applications to once processor and the other 5 to the other.

    Yes but with virus scans you get ALOT of HDD activity as well so you may still see other performance degridation. I usually would say something like converting an MPEG to an AVI at the same time as Web surfing. you set the converion affinity to CPU 1 and I.E. to CPU 0 and you will be golden.

    Dual Core is just that 1 processor that has 2 physical cores E.G.

    No I am saying most applications won't use both cores at the SAME TIME. This is the main reason gamers still like 1 fast single core CPU and application intesive people like 2 cores. Just like in the example on the first one your Video editing program may not be able to use BOTH cores to function it may only be able to use 1, your virus cscan can definitely only use 1 core. Only the multithreaded applications can use both cores at the same time.

    Basically I dumb it down as a VIRTUAL dual core. you still have a single core chip but the floating points are configured in such a way you can "split" the single core to use in a dual core type of way. This VIRTUAL setup however is not as efficient as a true dual core system.

    In all I say this -

    Hypertherading - 1 core "virtualized" into 2 CPU's with some performance hits due to floating point manipulation.
    Dual Core - 2 physical core CPU - Not as good for gaming as no current games can use both cores.
    Single core - Standard CPU setup that has been in place for years before dual core and hyperthreading. Still most popular for gamers.

    Nice sound like paradise and will would I get such a system? And you right doing a search for file on how hard-drive or doing virus scans/scan disk or defrag you should not be running other programs too much activity on the hard-drive!!


    So when will the games and Video editing program catch up with this technology? And will Office 2007 and Corel 12 support it?

    http://en.wikipedia.org/wiki/Office_2007

    What about multimedia?


    So it is only one core but it acts like dual core but not good has dual core :eek:

    Okay does Office 2007 and Corel 12 support Hypertherading ? What about games or Video editing program ?

    So this Hypertherading is special technology for processor that appear as dual core processor to the operating system and multi-threaded application but it really is one it fools the operating system and multi-threaded application and kinda works like dual core but not really :eek:

    Now this is the part that gets techy Each logical processor can execute a thread of a multi-threaded program

    Don't you what say Each logical processor can execute the data from each program?:eek:


    -execute -run, to perform an action, as in executing a program or a command.
    -multi-threaded program-=A program that supports multi-threaded technology


    Well I run about 5 programs so I could assign some work load to other CPU but can you assign with Windows 95 or Windows 98?

    And Windows Vista will not crash because it is running too many command for each CPU??

    I doubt that Windows 95 or 98 support dual-core CPUs.

    Vista shouldn't crash unless you are completely overloading both processors, at which point you would probably get a Blue Screen of Death. Don't worry about it, you'll be fine.

    Lets say that a "thread" is a stream of data. Multi-threaded applications have two threads - one for each processor.

    So basically, to simplify that sentence:
    Each processor can run half of the application.

    This is a huge advantage when working with intensive applications. It allows the application to run faster and puts less stress on the processors.

    Basically...

    Apps that do NOT support multi-threading:
    Dual-core will speed up the whole PC.

    Apps that DO support multi-threading:
    Dual-core will speed up the whole PC AND the multi-threaded application.

    Essentially, yes. The same apps that are multi-threading apps will use both virtual cores with hyper-threading.
    I'm not sure about any other multi-threading apps.

    Yes, that is a great way to visualize it.

    A single processor can only run one thread at a time. That thread takes up all of the processors power.
    A processor with hyper-threading can run two threads at a time, but the threads both use half of the processing power.

    In a dual-core CPU, two threads can run at the same time, but each thread uses up one core, not half of a core.
    In a dual-core CPU with hyper-threading, four threads can run at the same time, each using up a half of each core.

    Does that make sense?

    Basically, hyper-threading is a nice technology if you multi-task alot, but if you run just one intensive application at a time (i.e. games), a processor without hyper-threading would benefit you better.

    Anyone want to add anything? (And please correct me if I'm wrong!)
