Multi-core processors

A multi-core CPU (or chip-level multiprocessor, CMP) combines two or more independent cores into a single package.

A dual-core device contains two independent microprocessors and a quad-core device contains four microprocessors.

Signals between multicore CPUs travel shorter distances which allows more data to be sent in a given time period.

Software benefits from multicore architectures where code can be executed in parallel. Running virtual machines benefits from the adoption of multiple core architectures since each virtual machine runs independently of others and can be executed in parallel.

The largest boost in performance is in improved response time while running CPU-intensive processes, like anti-virus scanning, disk defragmenting, media ripping/burning, file conversion, and file search.
