Hey

 

A chap at work told me that it doesn't matter how many cores a processor

have, windowsXP wil use only 1 core

 

Is this true? And how are Vista on this subject?

No.

A quick search at Groups.Google.com raised this:

"In point of fact, XP Pro and XP Pro x64 support dual processors,

dual-core or quad-core. XP Home only supports one processor,

but that can be multi-core also. For workstations with four or more

processors you would have to install an appropriate edition of

Windows Server. Windows 2000 Professional always supported

dual procs. That was one of the reasons there was no upgrade path

from Windows 2000 to XP Home, it had to be W2k to XP Pro.

Try that question in a Vista NG.

No. It's completely false.

 

He may be thinking of two separate processors, but even there he's not

correct. Windows XP Home will only use one, even if you have two.

However XP Professional will use both.

Exactly the same.

XP does handle the dual core cpu quite nicely

No, it is not true. XP Home supports only one physical processor, but the

processor can have multiple cores. XP Pro supports two physical

processors. For more, you require a Server OS.

No.

 

XP Home can support a single processor with multiple cores. XP Pro can

supports two processor chips and multiple cores on each.

Vista is the same: for the home versions - only one processor with

multiple core support. Business versions support two processors and

multiple cores on each.
