What significance does duo core and quad core CPU mean?
Posted on 2007-10-15
When I source hardware for my server upgrade, I am confused by the duo core and quad core CPUs. Originally my CPU is duo core Intel Xeon 3.0GHz. Later the supplier quote me on quad core Intel Xeon 2.0GHz with lower price.
Q#1. What advantages does a duo/quad core CPU have over single core CPU?
Q#2. Is dual CPU better than single CPU with duo core given same brand and speed?
Q#3. Under what situations does a duo core/quad core CPU have performance advantage over single core CPU?
Q#4. How do I estimate the over performance with my two CPU configuration - duo core 3.0GHz vs quad core 2.0GHz?
Q#5. Any adivce on how to choose from these single/duo/quad core CPU?
Thanks a lot.
