CPU Speed / Dual Core etc..

I dont follow computer / technology much these days but when I bought my last PC things seemed easier to understand.

I understand RAM / Hard drive etc so that doesnt matter but how do you work out the best processer speed these days?

Back when I bought my PC it was Pentium 3.5GHZ, an upgrade from my old Pentium 1.5GHZ, basically the higher the GHZ the better the PC performance was ( or so I used to think )

Now when choosing a PC I am confused when looking at Dual core Quad Q2660 and Dual core Duo E4600 & similar things, which part of this do I look at to work out what I am getting?

I am either getting old or the descriptions of new processors are getting harder to understand, I used to be a whizz at stuff like this about 6-7 years ago

    single core 1 cpu

    duel core 2 cpu's

    quad core has 4 cpu's

    I lost 3 stones = 42lbs Im well happy!

    so what is a "Dual core Quad Q2660" ?

    2 cores and 4 Q2660's ??

    I think you mean "Intel Core 2 Quad Q2660" which is a single CPU with 4 processing cores, effectively 4 CPUs in 1.

    "Core 2" is Intel's second generation multi core CPU architecture, and I don't think they could have chosen a worse name for it.

    I think the Intel chips are not true 'quad' cores but simply 2 dual cores banged together in the same CPU, thus a quad core of a sort.

    (I may be wrong though!)

    They are still very fast and the top end beat AMD,s genuine quad core but cost far far more coin.

    Search Google bro for CPU benchmark test and there are some good charts which give the full specs.

    I bought a single CPU 3.6ghz dell PC in august 2004, it still runs all the latest games without any slow down. I was thinking about buying a new one because they're so cheap and with the limited research I've done, dual CPUs are apparently better than Quads because vey few games or anything that will require alot of processor speed are generally not taking advantage of more than the dual CPU so I've come to the conclusion anything more is a waste of cash

    Yeah thats right, sorry my mistake I was copying from the PC world website. Just double checked it.

    So does the numbers have any relevance to the speed? - would a Q2600 have 4 processors all running at 2600GHZ or am i missing the point

    if so would that make it a 10400GHZ

    There is no Q2600, you must be on about the Q6600.

    Higher mhz is better but the latest generation are much more efficient so a Core 2 at 2.0Ghz will beat an old P4 at 3.0Ghz.

    Yes all the cores run at the same speed, for the Q6600 this is 2.4Ghz, but no it doesn't make it the equivalent of a single 8.6Ghz core, because not every application is able to use 4 (or even 2 cores).

    It's only 4 times as fast in certain applications, some encoding/rendering software, WinRAR, certainly not games or Windows.

    Unfortunately the numbers don't have an easy link with the clockspeed, but for Intel it goes like this

    E2xxx - budget dual core
    E4xxx - not-so-budget dual core
    E6xxx - expensive dual core
    Q6xxx - quad core

    TBH for a typical 'home user' you may as well get the cheap E2xxx series, you wouldn't notice having 4 cores apart from the 100 extra notes missing from your wallet lol.

    You're right mate.
