Are there any Hardware expert can explain to us that is 4-way/8-way CPU mean it has 4/8 CPUs on motherboard? In addition, what is SMP?

Thanks in advance!

neo i am not sure if it explains 4-way/8-way CPU but you can read this....


Short for Symmetric Multiprocessing, a computer architecture that provides fast performance by making multiple CPUs available to complete individual processes simultaneously (multiprocessing). Unlike asymmetrical processing, any idle processor can be assigned any task, and additional CPUs can be added to improve performance and handle increased loads. A variety of specialized operating systems and hardware arrangements are available to support SMP. Specific applications can benefit from SMP if the code allows multithreading.

SMP uses a single operating system and shares common memory and disk input/output resources. Both UNIX and Windows NT support SMP.


A 4-way server provides fast performance and scalability by supporting multiple CPUs. In this case it would support four processors. The multiple CPUs available to complete individual processes simultaneously. The computer architecture used in 4-way servers is called SMP (Symmetric Multiprocessing).

An 8-way server (v880) does not necessarily have 8
processors.  So someone might say, the v880 is an
8-way even though it may only have 4 or 6 actual
processors installed.



for symmetric multiprocessing (SMP) see here:
http://en.wikipedia.org/wiki/Symmetric_multiprocessing

hope this helps.
