What is the difference between multi processor and multi core system ?

Question

As we heard of terms like multi processor and multi core system

Both are same or some difference exist between them ??

Answer 1

Multi-processor means mother board has multiple physical slot for each processor. In case of multi-core architecture, multiple cores has been introduced within the same chip. Since multiple core sits within the same chip, it performs better than multiple processor architecture.

Answer 2

Short Answer

Multicore - multiple cores in just one die.
Multiprocessors - More then one processor and each one in separate die.

Detail Description

A multiprocessor system contains more than one such CPU, allowing them to work in parallel i.e Simultaneous Multiprocessing.

A multicore CPU has multiple execution cores one one CPU which means that a certain subset of the CPU's components is duplicated, so that multiple "cores" can work in parallel on separate operations. This is called CMP, Chip-level Multiprocessing.
