    I think it is quite amazing! My computer shows as having 2 processors, which it only has 1! It is a Intel Core 2 Duo T6600, @2.20GHZ, and now i know i can set VMWare to use 2 processors, and 1 core each for better speeds! Anyone here have a story like mine, or just wanna talk about how hyperthreading is wonderful?!?!

    dude, its called CORE 2 DUO for a reason. It has TWO CORES!

    It says CORE 2, not processor 2 ???
    Anyone care to explain how 2 cores shows up as 2 processors then?...

    Dual core means two processors.

    To be sure, why don't you go to Device manager on your pc?

    Right click MY Computer, Choose Properties, Click hardware tab and then Device Manager.
    Then you have a list just Click Processors, count how many and tell us.

    Hyperthreading is not the same as multicore. You have a multicore processor.

    I guess i could have jumped to that conclusion since it seemed to fit what i just read about hyperthreading with the processor in me new computer =/

    hyperthreading is a virtualised processor that allows an additional thread to be executed in parallel to the thread being executed on the physical core. It takes resources (clock cycles and L1 cache) from the physical core in order to accomplish this, so the physical core takes a slight performance hit. Most software will not benefit from hyperthreading, and some is actually hindered by it.

    An additional physical core/processor allows execution of threads in parallel to those being executed on other physical cores/processors. It has its own resources (clock cycles and L1 cache) therefore there is no performance hit to other physical cores/processors. Most software will not benefit from extra cores (aside from the benefits provided to multitasking as a whole), but no software is hindered; the extra cores are just unused.

    So you mean to tell me that the new quad cores are useless...?

    for most people, there is a minor improvement in multitasking ability over a dual core (which has a significant improvement in multitasking ability over a single core), but other than that, yes. Six core, eight core and 12 core processors are only of benefit to people who run applications that need lots of processors (video rendering, 3d modelling, 3d animation and scientific fields)

    Also for people who likes to brag without a real use for multi cores. Like I have a the new AMD six core and you still have the quad core.

    Just like this shit guy who brags about the number or ram his computer has. Been bragging his 64-bit cause it can handle more than 4 GB of Ram cause i have only 32-bit and 2 GB or ram.... like why the hell would i have more when i only use my comp for simple task and old school gaming?

    I have a 32bit version of windows that can handle 128GB. My big computer only has 16GB currently, though. it uses expensive ram and modules 4GB and up are exceptionally expensive.

    Its amazing how the prossessors have doubled capacity over such a short period of time. Considering how slow computers were three decades ago. But yeah I only use both a single core CELERON at 2.3 Ghz and another AMD Athlon duo-core at 2.4 Ghz. Nothing really bothers me when I use the computers its just used for simple day to day tasks. I was a hardcore gamer, but PC became too expensive and I decided to lay low and wait for future hardware to go cheaper.

    Whenever hardware is excelled to a new capacity, it becomes the main thing.

    I also use something similar to that and I am quite content with what I have.

    yeah I'm going to upgrade my big computer to dual six core processors. For some reason its now cheaper to buy two faster six core processors than it is to buy one quad core identical to the one I have (they have to be matched).

    Sorry my earlier quote was out of reason , I was hypothetically speaking about its capabilities. I do not have a quad core, that thing will eat up my electricity bills for crying out loud.

    my 3.1Ghz dual core uses about half as much as my 2.2Ghz dual core (65W vs 110W), and the difference is only about 5 years. I bought the 2.2Ghz back when dual cores first came out, and then the 3.1Ghz in march this year.

    I know its surprising how energy efficient the faster ones are, under the same category. By the way do you use INTel or AMD. Some differences in the voltage may be the case.
