In the latest INTEL processor configuration says 4 core and 8 threads.By the statement i understood it is quad core processor but i am not sure about 8 threads.Any one explain what is meant by 8 threads and how it is different from OS threads.
its called hyperthreading!

HT cores are logical processors with own gp registers, apic and access to XMMn/YMMn SIMD unit.Those cores are seen by OS as a processing units which are availabe for OS thread scheduling.
OS threads are like a containers which encapsulate streams of basic units of execution(machine code and data).Such a threads are represented by its own context two stacks(user and kernel mode) and various internal data structures.
