Re: Which version support dual core or quad core?
Another interpretation is that the each cpu is a physical processor and each
core is a logical processor. You can see the logical processors on the
Performance Tab in Task Manager. There will be a CPU Usage History graph
for each logical processor.
Home editions can be installed on boards with one physical processor.
Business editions can be installed on boards with one or two physical
processors. Boards with more physical processors require one of the Server
editions.
Hyperthreading doubles the number of logical processors so an Intel P4 with
hyperthreading enabled appears exactly the same as an Intel Core Duo, Core 2
Duo, or AMD64 x2 on the Performance Tab.
All editions of XP, Vista, and Server work the same in this regard.
