Dual CPU ?
Is there any benefits to run Windows XP professional in Dual CPU PC ?
Will XP makes use of both CPU for faster processing ? |

Dual CPU ?
Not for most games.
And most other software may need to have been written so as to use the second CPU. "Alvin Brown" wrote in message ... Hi Yes Al johnn wrote: Is there any benefits to run Windows XP professional in Dual CPU PC ? Will XP makes use of both CPU for faster processing ? |

Dual CPU ?
If you paid for two CPUs and the motherboard, you must use
XP Pro for them to both be used at all, Windows XP Home will only see one processor. Windows XP Pro will see both CPUs and if the application or game is written to make use of two CPUs, then you will get an improvement in performance. The simple answer is that dual CPU REQUIRES XP Pro, otherwise you will only have one CPU support. -- The people think the Constitution protects their rights; But government sees it as an obstacle to be overcome.

Dual CPU ?
OK most of what's written so far is great: in summary then:-
To use Dual CPU with Windows XP one must install XP Pro. Two CPUs will ensure that for most applications and system functions, your throughput will be better than a single CPU: on the premise that you had one CPU in the first instance and then added an identical CPU in the second slot. If one were to compare 2 x 1.5Ghz CPUs verses 1 x 3.0Ghz CPU then the single CPU system will outperform a dual configuration. This is because of the 'overhead' on the system management functions when there is a multi CPU environment. A case of 1+1 is not equal to 2 but more like 1+1 = 2 - 12%. In order that an application can benefit from 2 CPs it must be written in such a manner as to allow for dual processor mode. Otherwise the Operating System has to manage that application using one a single CPU, so some games will behave as if you were running on a 1.5Ghz System, if we use the example above.

Hyperthreading is a different issue from dual processors.
