I recently purchased an Intel i5-650 processor. On the Intel site, this the technical specifications show that the processor should only have two cores.
http://www.intel.com/products/processor/corei5/specifications.htm
However, when I check the Performance tab in 'Windows Task Manager', it shows 4 sections under 'CPU Usage history', indicating 4 cores. Can someone confirm if I have two or four cores.
I have seen this behavior with two of my friends Intel i3 processors as well.
Thanks
2although the speedup varies significantly depending on the workload, you may expect about 30% speedup in total processor throughput (i.e. it's like having 2.6 cores) – netvope – 2010-11-29T06:24:46.393
