Newbie Question - Dual CPU

Hi All,

I have a question and hope any person can tell me or guide me to an article.

Say for example, one requirement for a server is with a CPU with Xeon 2.4GHz. Then the vendor said they don't have and came back with 2 x Xeon 1.2GHz. So may I know is 2 x 1.2GHz = 1 x 2.4GHz or better?

Thanks.

  1. Dual CPU is not CPU A + CPU B.

    To get full advantage of dual operation applications must be compiled with "multi-thread" or "multi-processor" operation.

    For example, if you play WarCraft on a DUAL 1.2GHz, the game will run like if it's on single 1.2GHz processor. But, on the other hand, the OS, can use the other 1.2GHz to do other stuff (video compression, etc...).

    One of my friend made this mistake 2 year ago, he bought a Dual Duron system! He tought that the speed would add up. But this was not the case. He returned back the rig and bought a single processor system.

    Dual CPU is for specific software or condition. And by the way, AMD CPU scales better in Dual mode than Intel CPU.

    This is short, but, I wish this will help you!

  2. Depends really. If you are into multi-taking on the machine then the dual rig may be the choice but Im leaning toward the 2.4 rig option here.
