2 or 4ghz with dual core?

Question

if you had a processor running at say 2ghz that was "dual core" does that double the power so its running at 4ghz or dose it mean something different.

what about core 2 duo is that the same thing or what?

Answer 1

Still 2gHz but two processors would run the applications, threads or tasks.

It's just like having 2 cars that can both do 100mph. No matter what you do with them, you can never make them run at 200mph. But 2 cars can do a lot more at the same time rather than having to wait for Dad's car when you have a date.

Answer 2

Nope, just two cores -- each running at 2ghz each. The processor frequency do not add up, as it performs individually.

Edit: Core 2 Duo is the highend dual core processor made by Intel Corporation. AMD, is the leading competitor of Intel, the Athlon X2 processor is their counterpart to Intel's offering.
