Newbie CPU question.

[MartinJK]

Hello there tech heads.
My question is regarding the Intel based CPU.
Does the Intel Pentium CORE 2 DUO E6420 2.13GHz 4MB run only at 2.13 Ghz or does the core 2 duo double the speed the this CPU?

 

[Exonimus]

it had two cores running at 2.13ghz. But you can't say it'd run at 4.26ghz. But the CPU itself runs on 2.13ghz, it just has two cores doing so.

It has TWO CPUs on ONE die each running at 2.13 at fully capacity. Bear in mind CPUs with cooling technology clock down the speed automatically to conserve energy and prevent heat when not needed.
Also NOT all programs can take advantage of multi-core CPUs.
